Organogel as a system was to estimate its capacity to delay and slow the drug release in the duodenum. The gelators, 12HSA (12-hydroxystearic acid), span 60. span 40 were used; the castor oil (CO) and anise oil (AO) also represented the liquid phase. To achieve the goal of this work was by using diclofenac sodium (DS). Organogels specifications were by estimating thermal attitude using tabletop rheology and differential scanning calorimetry (DSC). The organogel strength study was by applying oscillatory rheology tests the amplitude sweep and the frequency sweep. Realizing the morphology of the organogel was done utilizing an optical microscope. CO and AO binding capacity was also manifested. The transition temperatures for all organogels were reversible. Imaging demonstrated spherulites aggregates for organogels of 12HSA and span 40 in CO and AO while span 60 organogels in both oils existed as fibers aggregates. Furthermore, organogels exhibited viscoelastic characteristics as 20 wt% 12HSA in both oils were frequency-independent. The results revealed that the HPMC capsule containing the organogel resisted the dissolution in the acidic media for two hours. Moreover, organogels slowed the release of DS for 24 hours in an alkaline medium. Finally, all the selected organogel in CO exhibited a high oil binding capacity.
将有机凝胶作为一种系统来评估其延缓和减缓药物在十二指肠释放的能力。凝胶,12HSA(12-羟基硬脂酸),跨度60。跨度40个;蓖麻油(CO)和茴香油(AO)也代表液相。采用双氯芬酸钠(DS)来达到本研究的目的。通过桌面流变学和差示扫描量热法(DSC)估计热态来确定有机凝胶的规格。通过振荡流变试验、振幅扫描和频率扫描对有机凝胶的强度进行了研究。利用光学显微镜实现了有机凝胶的形态。CO和AO的结合力也得到了体现。所有有机凝胶的转变温度都是可逆的。成像显示,在CO和AO中,12HSA和span 40的有机凝胶呈球粒聚集体,而在两种油中,span 60的有机凝胶以纤维聚集体的形式存在。此外,有机凝胶表现出粘弹性特性,两种油中20 wt%的12HSA与频率无关。结果表明,含有机凝胶的HPMC胶囊在酸性介质中抗溶出2小时。此外,在碱性培养基中,有机凝胶延缓了DS的释放24小时。最后,所有选择的有机凝胶在CO中都表现出较高的油结合能力。

Treatment of Helicobacter Pylori Infections Using Moxifloxacin-Triple Therapy Compared to Standard Triple and Quadruple Therapies 莫西沙星三联疗法治疗幽门螺杆菌感染与标准三联和四联疗法的比较
M. Mohammed
Helicobacter pylori (H. Pylori) is one of the most common infectious human pathogens. H. pylori could induce inflammation, that causes illnesses and disorders of upper gastrointestinal which including peptic ulcer diseases, dyspepsia, gastroesophageal reflux disease and gastric mucosa-associated lymphoid tissue (MALT) lymphoma. It is important to use a better tolerated and greatly effective eradication regimen. In this study, 75 newly diagnosed adult patients with H. pylori infection were included and completed the study, they were allocated into three groups with three different treatment regimens for H. pylori eradications; Group A (25 patients) received oral standard clarithromycin-based triple therapy for 14 days. Group B (25 patients) received oral bismuth based-quadruple therapy for 10 days. Group C (25 patients) received oral moxifloxacin-based triple therapy for 14 days. The results reported in this study indicated a significant higher eradication rate of Group B and Group C (84% and 80%, respectively) of patients with H. pylori infections compared to that of Group A (52%). The incidence of adverse effects were appeared as 72%, 64% and 24% of patients in group A, B and C respectively. The use of moxifloxacin triple regimen for H. pylori eradication, present with eradication efficacy parallel to that of quadruple regimen which were significantly higher compared to that of clarithromycin triple regimen. Also moxifloxacin triple therapy is more tolerable and does not increase the incidence of overall adverse effects compared to other regimens used in this study.
幽门螺杆菌(Helicobacter pylori, H. pylori)是人类最常见的感染性病原体之一。幽门螺杆菌可引起炎症,引起上消化道疾病和紊乱,包括消化性溃疡疾病、消化不良、胃食管反流病和胃黏膜相关淋巴组织淋巴瘤。重要的是采用一种耐受性更好和非常有效的根除方案。本研究纳入75例新诊断的成人幽门螺杆菌感染患者并完成研究,他们被分为三组,采用三种不同的治疗方案根除幽门螺杆菌;A组(25例)接受口服标准克拉霉素三联疗法,疗程14天。B组(25例)口服以铋为主的四联疗法,疗程10天。C组(25例)采用口服莫西沙星三联疗法,疗程14天。本研究报告的结果表明,B组和C组幽门螺杆菌感染患者的根除率(分别为84%和80%)显著高于a组(52%)。A、B、C组不良反应发生率分别为72%、64%、24%。莫西沙星三联方案根除幽门螺杆菌的效果与四联方案相当,且明显高于克拉霉素三联方案。此外,莫西沙星三联疗法的耐受性更强,与本研究中使用的其他方案相比,不会增加总体不良反应的发生率。

Fluoxetine (FX) is an antidepressant drug administered only orally in humans. Despite the wide use of FX, until now, there is only limited literature concerning the pharmacokinetics (PK) of FX and the effect of food on its PK. Thus, the objective of this investigation was to study the PK of FX in Arabic healthy male adult volunteers under fasting and fed conditions. In the fasting study, FX 20 mg capsules (Prozac®, Eli Lilly, Canada) were administered to 41 volunteers after overnight fasting of 12 hours, followed by blood sampling from each volunteer immediately before dosing (zero time) and then at 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 24, 36, 48, 60, 72, 96, 120, and eventually at 144 hours after FX dosing. The fed study was conducted after 90 days wash-out period following the completion of the fasting study. The same subjects who received FX in the fasting study were administered the drug directly after a fatty breakfast (fed study), followed by blood sampling intervals similar to the schedule mentioned above for the fasting study. The current investigation demonstrated no statistical differences in the FX pharmacokinetic parameters Cmax, AUC0–t, AUC0–∞, Kel, T1/2, MRT, Cl/F, and Vd/F after fasting compared to the fed conditions, whereas there was statistically significant elongation in the Tmax values after food intake. Therefore, this study concludes the absence of food effect on the PK of FX (except Tmax) in the Arabic population and confirms the method of administration mentioned in the product information but also concludes high interindividual variation in FX exposure (AUC), which suggest that therapeutic drug monitoring (TDM) might be advisable when feasible.
氟西汀(FX)是一种只能口服的抗抑郁药物。尽管FX被广泛使用,但迄今为止,关于FX的药代动力学(PK)以及食物对其PK的影响的文献很少。因此,本研究的目的是研究阿拉伯健康成年男性志愿者在禁食和喂食条件下的FX的PK。在禁食研究中,41名志愿者在禁食12小时后给予FX 20mg胶囊(百zac®,Eli Lilly,加拿大),然后在给药前(零时间)立即对每位志愿者进行血液采样,然后在FX给药后1、2、3、4、5、6、7、8、9、10、12、24、36、48、60、72、96、120,最终在给药后144小时进行血液采样。禁食研究结束后,在90天的洗脱期后进行喂养研究。在禁食研究中接受FX的同一受试者在高脂肪早餐(喂养研究)后直接给药,然后进行与上述禁食研究相似的血液采样间隔。本研究显示,空腹后FX药代动力学参数Cmax、AUC0 - t、AUC0 -∞、Kel、T1/2、MRT、Cl/F和Vd/F与进食条件相比无统计学差异,而进食后Tmax值有统计学显著延长。因此,本研究得出结论,在阿拉伯人群中,食物对FX的PK没有影响(Tmax除外),并证实了产品信息中提到的给药方法,但也得出结论,FX暴露(AUC)的个体间差异很大,这表明在可行的情况下,治疗药物监测(TDM)可能是可取的。

High percentage of the Iraqi population profoundly rely on folk medicine to meet their health needs which makes their safety questionable. This study aims to evaluate Iraqi herbalists' knowledge and practice to ensure the public's safety.This study was conducted in a cross-sectional design between October 2021 and March 2022, using a pretested questionnaire administered to Iraqi herbalists practicing in Middle Euphrates Area. Through face-to-face meetings, participants completed a multicomponent questionnaire comprising 15 items in four sections. The data obtained were analyzed using a statistical package for social sciences; Chi-square was used to correlate some variables, and P-values of <0.05 were considered significant. A total of 54 male herbalists from five Iraqi provinces joined this survey, the majority practicing in Kabala. Most herbalists had 10- 20 years of experience, and more than 50% had a university degree. Data showed that 72.2% of herbalists identify their herbal items using their own experience, and 35.2% use this experience as their sole source of knowledge. Only 35.1% use herbal books in conjugation with their experiences, and a few (1.9%( use multiple sources of information. Herbalists with more years of experience (79.6%( evaluate patient conditions properly, follow up (40.7%(, and refer patients to their physicians when needed (42.6%(. Although fifty percent of herbalists educate their patients regarding the storage condition of remedies, most of them refrain from writing the complete ingredients on their final product regardless of their experience. Results also showed that most herbalists do not have a record tracking adverse reaction.Most Iraqi herbalists lack the proper system for prescribing and dispensing their remedies and adequately identifying the sold herbs. The study showed a variation in practice among herbalists using approaches based mainly on their experience.
很大比例的伊拉克人严重依赖民间医药来满足他们的健康需要,这使他们的安全受到质疑。本研究旨在评估伊拉克中医的知识和实践,以确保公众的安全。本研究在2021年10月至2022年3月期间采用横断面设计进行,使用预先测试的问卷调查在幼发拉底河中部地区执业的伊拉克草药医生。通过面对面的会议,参与者完成了一份由四个部分组成的问卷,其中包括15个项目。获得的数据使用社会科学统计软件包进行分析;采用卡方法对部分变量进行相关性分析,p值<0.05为显著性。来自伊拉克5个省的54名男性草药医生参加了这项调查,其中大多数在卡巴拉执业。大多数中药师有10- 20年的工作经验,超过50%的中药师有大学学历。数据显示,72.2%的中药师使用自己的经验来确定他们的草药项目,35.2%的人将这种经验作为他们唯一的知识来源。只有35.1%的人将草药书与他们的经验结合起来使用,少数人(1.9%)使用多种信息来源。具有多年经验的中药师(79.6%)正确评估患者病情,随访(40.7%),并在需要时将患者转介给医生(42.6%)。尽管50%的草药医生会教育他们的病人关于药物的储存条件,但他们中的大多数人都不会在他们的最终产品上写下完整的成分,不管他们有什么经验。结果还显示,大多数中药师没有不良反应记录。大多数伊拉克草药医生缺乏适当的系统来开处方和分发他们的药物,并充分识别出售的草药。该研究表明,在实践中,草药医生主要根据自己的经验使用不同的方法。

There were several goals in this study, the most important of which was to create an oral liquid preparation (Ion sensitive floating oral in situ gel system for sustained delivery of Montelukast Sodium for pediatric patients) that would make administration easier, provide the correct therapeutic dose, and allow the drug to be released more slowly into the digestive tract (GIT) for better control. Montelukast Sodium in situ gels at different concentration (w/v) of natural polysaccharides (Gellan gum and sodium alginate) and natural polymer (Pectin) were prepared and characterized in the terms of preparation, viscosity and In vitro release. As the concentrations of ion-sensitive gel-forming components (Gellan gum, sodium alginate, and pectin) and gas-generating ingredients increased, the viscosity of formulations in solution (CaCO3). In vitro release study showed that the release of Montelukast Sodium from these gels was characterized by an initial phase of high release (burst effect), followed by a more gradual release in the second phase. The oral distribution of Montelukast Sodium using the in situ gel system manufactured by Montelukast Sodium can be seen as a viable strategy for the improvement of therapeutic effects. 
本研究有几个目标,其中最重要的是创造一种口服液制剂(用于儿科患者持续递送孟鲁司特钠的离子敏感漂浮口服原位凝胶系统),使给药更容易,提供正确的治疗剂量,并使药物更缓慢地释放到消化道(GIT),以更好地控制。制备了天然多糖(结冷胶和海藻酸钠)和天然聚合物(果胶)不同浓度(w/v)的孟鲁司特钠原位凝胶,并对孟鲁司特钠的制备、粘度和体外释放度进行了表征。随着离子敏感型成胶成分(结冷胶、海藻酸钠和果胶)和产气成分浓度的增加,溶液中配方的粘度(CaCO3)也随之增加。体外释放研究表明,孟鲁司特钠从这些凝胶中释放的特征是初始阶段高释放(爆裂效应),随后在第二阶段释放更为缓慢。使用孟鲁司特钠制造的原位凝胶系统口服孟鲁司特钠可以被视为一种改善治疗效果的可行策略。

Knowledge, Perception, and Reporting Practices of Healthcare Providers about Adverse Events Following the COVID-19 Vaccination in Iraq(Conference Paper )# 伊拉克医疗保健提供者关于COVID-19疫苗接种后不良事件的知识、感知和报告实践(会议论文)#
Pub Date : 2023-02-18 DOI: 10.31351/vol31issSuppl.pp168-177
B. Al-Metwali, Farah Hatem Nsaif
 Routine vaccination activities, such as detection, reporting, and management of adverse events following immunization (AEFIs), are generally handled by healthcare providers (HCPs). Safe vaccines against severe acute respiratory syndrome coronavirus (SARS-CoV-2) were introduced to control the Coronavirus Disease-19 (COVID-19) pandemic. The study aimed to assess the knowledge, perceptions, and practice of HCPs in Iraq about reporting adverse events following COVID-19 vaccination, and their association with sociodemographic variables. The study was a cross-sectional study that was carried out between August and September 2021 at the COVID-19 vaccination centers in Iraq. This study used an online and paper-based questionnaire, which was distributed among HCPs (physicians and pharmacists) in COVID-19 vaccination centers. A total of 117 pharmacists and physicians responded to the survey. Two-thirds of respondents were pharmacists. The majority of the respondents (49.6%) had fair knowledge levels on AEFIs. The perception of 43% of the participants was very good, whereas the perception of 28%, 23%, and 6% of the participants was fair, good, and poor, respectively. The reporting practice of HCPs was inadequate in 53% of respondents. The number of pharmacists who had good knowledge of AEFIs was significantly higher than that of the physicians. The age group (30-39) years of HCPs was significantly associated with more positive perception towards AEFIs. The number of pharmacists that had good perception was significantly higher than that of the physicians. Furthermore, HCPs aged 30 to 39 years had significantly higher reporting practices than other age groups. The study highlighted that the HCPs working at the COVID-19 vaccination centers have low knowledge of AEFIs. On the other hand, HCPs had more positive perception towards reporting AEFIs. Education programs and reference materials are needed to increase their awareness about AEFIs.
常规疫苗接种活动,如免疫接种后不良事件的检测、报告和管理(AEFIs),通常由卫生保健提供者(HCPs)处理。为控制2019冠状病毒病(COVID-19)大流行,引入了针对严重急性呼吸综合征冠状病毒(SARS-CoV-2)的安全疫苗。该研究旨在评估伊拉克医务人员在报告COVID-19疫苗接种后不良事件方面的知识、观念和做法,以及它们与社会人口变量的关系。该研究是2021年8月至9月在伊拉克COVID-19疫苗接种中心进行的一项横断面研究。本研究使用在线和纸质问卷,在COVID-19疫苗接种中心的HCPs(医生和药剂师)中分发。共有117名药剂师和医生参与了调查。三分之二的受访者是药剂师。大多数受访者(49.6%)对aefi有一定的了解。43%的参与者认为“非常好”,而28%、23%和6%的参与者认为“一般”、“好”和“差”。53%的应答者对卫生专业人员的报告不充分。药师对AEFIs有较好认识的人数明显高于医师。HCPs的年龄组(30-39岁)与对aefi的积极看法显著相关。药师感觉良好的人数明显高于医师。此外,30至39岁的卫生保健专业人员的报告实践明显高于其他年龄组。该研究强调,在COVID-19疫苗接种中心工作的医护人员对aefi的了解程度较低。另一方面,医护人员对报告aefi有更积极的看法。需要教育计划和参考资料来提高他们对aefi的认识。

Nefopam (N.F.) HCl is a non-narcotic centrally-acting, non-opioid benzoxazocine analgesic to relieve acute and chronic pain. It exhibits low bioavailability (about 36%) due to its first-pass degradation in the liver. Intranasal administration has been used as a new route for targeting active brain sites and enhancing the bioavailability of N.F. HCl bypassing hepatic metabolism. In situ gel of N.F. HCl was prepared by the cold method using different concentrations of Poloxamer 407, Poloxamer 188, HPMC K4M, Carbapol 934, and Hyaluronic acid polymers. The results show that identification tests are superimposed with references, solubility study shows that N.F. HCl is suitable to be administered intranasally; Compatibility studies reveal incompatibility of Nefopam HCl with HPMC K4M and Carbapol 934; meanwhile, no interaction with Methylcellulose and Hyaluronic acid. In conclusion, the obtained results revealed the incredible ability of the produced N.F. HCl intranasal in situ gel is intended to enhance drug bioavailability bypassing the metabolizing effect of the liver that N.F. HCl is facing when given orally.
Nefopam (N.F.)盐酸是一种非麻醉性中枢作用非阿片类苯并恶唑镇痛药,用于缓解急性和慢性疼痛。由于其在肝脏中的首次降解,其生物利用度较低(约36%)。鼻内给药已被作为一种新的途径,用于靶向脑活动部位,并通过肝脏代谢提高盐酸n.f.h cl的生物利用度。采用不同浓度的poloxam407、poloxam188、HPMC K4M、Carbapol 934和透明质酸聚合物,采用冷法制备N.F. HCl原位凝胶。结果表明,鉴定试验与参考文献重叠,溶解度研究表明,nf.hcl适合鼻内给药;配伍研究发现盐酸奈福泮与HPMC K4M和卡波波尔934不配伍;同时,与甲基纤维素和透明质酸无相互作用。总之,所获得的结果显示,所生产的盐酸N.F.鼻内原位凝胶具有令人难以置信的能力,旨在提高药物的生物利用度,绕过口服盐酸N.F.所面临的肝脏代谢作用。

The use of antibiotics without prescription (self-medication) is growing globally and is associated with increased bacterial resistance, ineffective treatment and adverse reactions. This study aimed at assessing the practice of antibiotic self-medication in the Iraqi population. A cross-sectional study design was adopted in this work. The sample was comprised of 303 staff members from the non-medical colleges in Iraq. An online questionnaire was distributed between the 29th of June to the 14th of September 2021 to collect data including socio-demographic characteristics and questions about antibiotic self-medication. Most of the participants had a university degree and a moderate monthly income. The majority (88%) have practiced self-medication at least once before. A “simple” condition and convenience were the main motivators behind self-medication, which was mainly used for sore throat, fever and cough. Own experience was the most reported determining factor for selecting an antibiotic, and community pharmacies were the main source for obtaining the antibiotics. About 40% of the participants admitted to switching the antibiotic or changing its dose during the treatment course. Self-medication with antibiotics is a major issue in our community and measures have to be taken to reduce its impact on public health through the development of bacterial resistance.
在全球范围内,无处方使用抗生素(自我用药)的情况正在增加,这与细菌耐药性增加、治疗无效和不良反应有关。本研究旨在评估伊拉克人口中抗生素自我用药的做法。本研究采用横断面研究设计。样本包括来自伊拉克非医学院的303名工作人员。在2021年6月29日至9月14日期间分发了一份在线问卷,以收集包括社会人口统计学特征和抗生素自我用药问题在内的数据。大多数参与者都有大学学历和中等月收入。大多数人(88%)之前至少进行过一次自我药疗。“简单”的条件和方便是自我药疗背后的主要动机,主要用于喉咙痛、发烧和咳嗽。个人经验是选择抗生素的最主要决定因素,社区药房是获得抗生素的主要来源。大约40%的参与者承认在治疗过程中更换了抗生素或改变了剂量。使用抗生素自行用药是我们社区的一个主要问题,必须采取措施,通过细菌耐药性的发展来减少对公众健康的影响。

Combination of FDM 3D Printing and Compressed Tablet for Preparation of Baclofen as Gastro-Floating Drug Delivery System (Conference Paper )# FDM 3D打印与压缩片剂联合制备巴氯芬胃漂浮给药系统(会议论文)#
Pub Date : 2023-02-16 DOI: 10.31351/vol31isssuppl.pp18-24
Nuha Mohammed Abdulkhaleq, M. M. Ghareeb
This study aimed to develop an oral drug delivery system for gastro-retentive sustained drug release of baclofen by using a 3D printed capsular device since baclofen has a short half-life of 2.5 to 4 hours and has a narrow absorption window. Firstly sustained-release tablets of baclofen were formulated through the hot-melt extrusion of various thermoplastic polymers and direct compression of the extrudate, then a capsular device was designed and 3D printed to contain two air pockets to enable floating of the device and has four windows for drug release. 3D printing of the capsular device was done by an FDM printer using biodegradable PLA filament, and the sustained release tablets were inserted into the device to allow the medicine to be released into the stomach over a longer period. An in vitro buoyance test and an in vitro dissolution test were used to examine the buoyancy and sustained-release features of the formulated gastro-floating system. Five sustained release formulas were developed using different thermoplastic polymers in hot-melt extrusion. Produced tablets were assayed for drug content, hardness, and friability while a DSC study was done on the selected formula. F 5 which contains 20% baclofen, 55% Eudragit RS-100, 20% ethylcellulose, and 5% PEG 4000 showed sustained release where the complete dissolution of the drug occurred in 12 hours, and the gastro-floating device remained floating all the time. This method has a great potential for developing various floating drug delivery systems with the required release profile.
由于巴氯芬的半衰期较短,仅为2.5 ~ 4小时,吸收窗口较窄,本研究旨在利用3D打印胶囊装置开发一种用于巴氯芬胃保留性持续释放的口服给药系统。首先通过热熔挤压各种热塑性聚合物,直接压缩挤出物,配制巴氯芬缓释片,然后设计并3D打印胶囊装置,该装置包含两个气囊,使装置能够漂浮,并具有四个药物释放窗口。胶囊装置的3D打印由FDM打印机完成,使用可生物降解的PLA长丝,并将缓释片插入装置中,使药物在较长时间内释放到胃中。采用体外浮力试验和体外溶出试验考察了所配制胃浮系统的浮力和缓释特性。采用不同的热塑性聚合物进行热熔挤压,研制了5种缓释配方。对所制片剂进行药物含量、硬度、脆性测定,并对所选配方进行DSC分析。含20%巴氯芬、55%乌龙油RS-100、20%乙基纤维素、5% PEG 4000的f5表现为缓释,药物在12小时内完全溶解,胃漂浮装置一直保持漂浮状态。该方法具有开发各种具有所需释放谱的漂浮药物递送系统的巨大潜力。

This research concentrate on cultivated Iraqi Agave attenuata dried leaves and roots, because of little studies on this plant especially on the root that lead to the eager of study and comparison of phytochemical constituents between leaves and root. Extraction of bioactive constituents was carried out using several solvents with increasing polarity (n-hexane, ethyl acetate and methanol) by soxhlet apparatus. Steroidal saponins in Agave genus is well documented in many species, lightening the minds in this research on extraction method which is specific for steroidal saponins. Phytochemical screening was done by GC/MS for n-hexane fraction, qualitative and quantitative estimation of several bioactive constituents (caffeic acid, p-coumaric acid, and quercetin) for ethyl acetate and methanol fractions while for steroidal saponins (sarsasapogenin, hecogenin and tigogenin) in both leaves and root by using reverse phase-high performance liquid chromatography (RP-HPLC). Among those identified phytochemical constituents, several constituents have not been detected in Agave attenuata leaves and roots before. This study is the first to describe the results in which the highest concentration of caffeic acid was found in leaves ethyl acetate fraction, p-coumaric acid and quercetin in root ethyl acetate fractions. While for steroidal saponins, the hecogenin, tigogenin and sarsasapogenin highest concentrations were found in leaves.    
由于对伊拉克龙舌兰的研究较少,特别是对其根的研究较少,因此迫切需要对其叶和根的化学成分进行研究和比较。采用索氏装置,采用极性递增的溶剂(正己烷、乙酸乙酯和甲醇)提取活性成分。龙舌兰属甾体皂苷在许多物种中都有丰富的文献记载,这为研究甾体皂苷的提取方法提供了新的思路。采用GC/MS对正己烷部分进行了植物化学筛选,乙酸乙酯和甲醇部分对咖啡酸、对香豆酸和槲皮素等生物活性成分进行了定性和定量分析,对叶和根中的甾体皂苷类成分进行了反相高效液相色谱(RP-HPLC)分析。在这些鉴定的植物化学成分中,有一些成分是以前未在龙舌兰叶和根中检测到的。本研究首次报道了咖啡酸在叶片乙酸乙酯部位含量最高,对香豆酸和槲皮素在根乙酸乙酯部位含量最高的结果。而甾体皂苷中,黄豆素、虎皮素和菝葜皂苷在叶片中含量最高。
