Summary Introduction: Murraya koenigii L. and Ficus carica L. have been traditionally used in folk medicine for treating several diseases. Objective: The present study was proposed to investigate the phytochemical constituents and antioxidant potential of hydro-alcoholic and aqueous extracts of leaves of M. koenigii and dried fruits of F. carica. Methods: Phytochemical screening was performed using different methods and antioxidant activity was evaluated by measuring total phenolic content, total antioxidant capacity (TAOC), hydrogen peroxide (H2O2) scavenging activity, DPPH radical-scavenging activity, reducing power assay, nitric oxide radical scavenging activity, and superoxide radical-scavenging activity. Results: The results showed that the hydro-alcoholic and aqueous extracts of leaves of M. koenigii and dried fruits of F. carica possess a significant quantity of flavonoids, saponins, terpenoids (9.0%, 0.9%, 0.6% and 7.3%, 8.7%, 0.44%, respectively) and also possess a significant antioxidant activity as evaluated by employing different antioxidant assays. Conclusion: It may be concluded that the hydro-alcoholic and aqueous extracts of leaves of M. koenigii and dried fruits of F. carica exhibit significant antioxidant activity.

Summary Objective: Chamomile plants (Chamomilla recutita L. Rausch) are often attacked by pests, which usually cause the decrease of raw material yield and its quality. The objects of field trial were two chamomile cultivars: Złoty Łan (4n) and Promyk (2n) cultivated under organic regime. The aim of this study was to evaluate of impact of the spinosad treatment and its time of application on two chamomile cultivars: cv. Promyk – 2n and cv. Złoty Łan – 4n exposed to insect pests. Methods: The first treatment with spinosad as a preventative control (P) was performed in the early phase of plant development (seven leaves). Intervention (I) treatment was made in green bud phase. In both terms of observation insect pests were observed and collected. In each spraying application of 0.06 g of spinosad per 1 liter of water was used. Results: Spinosad was able to limit the number of pest population and finally increased yielding of the treated cultivars as compared to the untreated plants. Time of spinosad application for cv. Złoty Łan plants was not statistically siginificant, although was more effective for the preventative treatment of cv. Promyk in the increasing of the plant biomass (283.8 g · m−2) and seed (32 g · m−2) yields than intervention. Conclusion: Protection treatment with spinosad might be recommended in chamomile cultivation and it is more effective than intervention in diploid cultivar which begin blooming earlier than tetraploid. Essential oil content was not related with protection treatment for diploid cultivar, although intervention in tetraploid cultivar caused higher content of oil.
摘要目的:洋甘菊(Chamomilla recitita L.Rausch)经常受到害虫的攻击,通常会导致原料产量和质量下降。田间试验的对象是两个洋甘菊品种:ZłotyŁan(4n)和Promyk(2n),在有机条件下栽培。本研究的目的是评估多刺酸处理及其施用时间对暴露于害虫的两个洋甘菊品种:Promyk–2n和ZłotyŁan–4n的影响。方法:在植物发育的早期阶段(七片叶子),首次用多杀菌素作为预防性对照(P)。干预(I)治疗在绿芽期进行。在这两项观察中,都对害虫进行了观察和收集。在每次喷洒中,每1升水使用0.06克多杀菌素。结果:与未处理的植物相比,多杀菌素能够限制害虫种群数量,并最终提高处理品种的产量。ZłotyŁan植物施用多杀菌素的时间在统计学上并不显著,尽管与干预相比,预防性处理Promyk在提高植物生物量(283.8 g·m−2)和种子产量(32 g·m–2)方面更有效。结论:在洋甘菊栽培中,多刺酸的保护性处理可能是推荐的,并且对比四倍体早开花的二倍体品种的保护性治疗比干预更有效。对二倍体品种的保护处理与精油含量无关,但对四倍体品种的干预使精油含量升高。

Summary Introduction: Plants are a rich source of healing substances. Cancer is a leading cause of death worldwide while breast cancer is the most common cancer among women. Circulating tumour cells (CTCs) are potential founder cells for metastasis. Therefore, their assessment may be used for monitoring of treatment as well as detecting cancer metastatis. Hence, it is suggested that the number of CTCs may be a valuable tumour biomarker during therapy. Objective: The purpose of this study was to detect CTCs in breast cancer and to validate the method of assessment of CTC count using CytoTrack CT11 technology. Methods: MCF-7 cells were sorted by a FACSARIA flow cytometer from blood samples derived from patients who have not been diagnosed with cancer. Identification and quantitative assessment of MCF-7 cells in blood samples were determined by flow sorting. Then, blood samples containing MCF-7 cells or without MCF-7 were scanned with the use of an automated fluorescence scanning microscope. Results: In in vitro model analysing the glass CytoDisc™ with stained MCF-7 cells, we noted the correlation between the amount of observed tumour cells and expected number of tumour cells. Moreover, coefficient of variation in case of the recovery rate of the assumed number of MCF-7 cells was 30%, 17%, 18% and 15%, respectively. Conclusion: Our study suggest that CTCs could be predictive factor in patients with metastatic cancer especially in breast cancer.
简介:植物是一种丰富的治疗物质来源。癌症是全球死亡的主要原因,而癌症是女性中最常见的癌症。循环肿瘤细胞(CTC)是潜在的转移奠基细胞。因此,他们的评估可以用于监测治疗以及检测癌症转移。因此,有人认为CTC的数量可能是治疗过程中有价值的肿瘤生物标志物。目的:本研究旨在检测癌症中的CTC,并验证CytoTrack CT11技术评估CTC计数的方法。方法:用FACSARIA流式细胞仪从未被诊断为癌症的患者的血液样本中分离MCF-7细胞。通过流式分选测定血液样品中MCF-7细胞的鉴定和定量评估。然后,使用自动荧光扫描显微镜扫描含有MCF-7细胞或不含MCF-7的血液样品。结果:玻璃细胞盘体外模型分析™ 对于染色的MCF-7细胞,我们注意到观察到的肿瘤细胞的数量与预期的肿瘤细胞数量之间的相关性。此外,假设MCF-7细胞数量的回收率的情况下的变异系数分别为30%、17%、18%和15%。结论:CTCs可能是转移性癌症特别是癌症的预测因素。

Summary Introduction: Coreopsis tinctoria Nutt. is an annual plant with small flowers in yellow and claret. In dyeing process, a whole range of colours can be obtained using various methods. Objective: The aim of the study was to present a wide range of colors of the little-known plant C. tinctoria. and its health promoting properties. Methods: In our research, we selected 3 types of wool: Polish Merino, Żelaźnieńska, and Polish Lowland Sheep and compared the colours obtained on these wools using 6 dyeing methods. Results: The results indicate that the basic colour of wool influences the intensity of colour after dyeing as well as the type of the used mordant, which determines the obtained colour. A whole range of very intense colours was obtained from very small flowers of C. tinctoria. Conclusions: Flowers are a very good and efficient raw material that gives intense colors on wool. An additional advantage is the plant's health-promoting properties. The plant is still little explored in this respect.

Summary Introduction: Combretum species has been utilised for decades in African indigenous medical practices for the treatment of several parasitic infections. Objectives: This study aims at investigating the antileishmanial, antiplasmodial and antitrypanosomal properties of Combretum racemosum, Combretum platypterum and Combretum zenkeri. Methods: The leaf extracts of the plants were screened against two strains of Plasmodium falciparum using Plasmodium lactate dehydrogenase (pLDH) assay; promastigote and amastigote forms of Leishmania donovani; and Trypanosoma brucei brucei using Alamar Blue assay. Cytotoxicity screening were also carried out on African green monkey kidney cell line (Vero) and human monocytic leukemia (THP-1) cell lines. Results: C. racemosum was active against chloroquine-sensitive (D6) and chloroquine-resistant (W2) strains of P. falciparum (IC50 of 25.6 and 26.7 µg/ml, respectively) and exerted significant antiprotozoal activities against T. brucei brucei (IC50 = 18.44 µg/ml). The extract of C. platypterum displayed a slightly lower antiplasmodial activity when compared to C. racemosum, while C. zenkeri was inactive against the parasites. In addition, the extracts failed to display significant inhibitory activity on the proliferation of L. donovani. Conclusions: This study supports the ethnomedicinal use of C. racemosum. Further research needs to be carried out to identify the antiprotozoal compounds in C. racemosum, as this could be explored for possible antiprotozoal drug development.
简介:几十年来,Combretum物种在非洲本土医疗实践中被用于治疗几种寄生虫感染。目的:本研究旨在研究外消旋Combretum、桔梗Combretum platypterum和泽克里Combretum zenkeri的抗利什曼原虫、抗疟原虫和抗锥虫体特性。方法:采用乳酸疟原虫脱氢酶(pLDH)法对两株恶性疟原虫进行叶提取物的筛选;杜氏利什曼原虫的前鞭毛虫和无鞭毛虫形式;和使用Alamar Blue测定的布鲁氏锥虫。还对非洲绿猴肾细胞系(Vero)和人单核细胞白血病(THP-1)细胞系进行了细胞毒性筛选。结果:外消旋藻对氯喹敏感株(D6)和氯喹抗性株(W2)具有活性(IC50分别为25.6和26.7µg/ml),对布鲁氏菌具有显著的抗原生动物活性(IC50=18.44µg/ml)。与外消旋伞相比,桔梗提取物的抗疟原虫活性略低,而岑克里伞对寄生虫无活性。此外,提取物对donovani乳杆菌的增殖没有显示出显著的抑制活性。结论:本研究支持外消旋藻的民族医药用途。需要进行进一步的研究来鉴定外消旋藻中的抗原生动物化合物,因为这可以为可能的抗原生动物药物开发进行探索。

Summary Introduction: Potato (Solanum tuberosum L.) is an important vegetable crop in Syria. Potato tuber moth Cussonia barteri is a small tree that grows in the sub-Saharan part of Africa. Various parts of the plant are used for the treatment of a variety of ailments in ethno-medicine. Objective: To evaluate the anti-inflammatory and analgesic effect of the methanol leaf extract of Cussonia barteri. Material and methods: The leaves were air-dried, powdered and repeatedly extracted with methanol using a Soxhlet apparatus. The resulting methanol extract (100, 200 and 400 mg/kg) was evaluated for anti-inflammatory activity using carrageenan-induced paw oedema, xylene-induced ear oedema and formalin-induced arthritis tests. Analgesic effect was evaluated using acetic acid-induced mouse writhing, hot plate and tail flick tests. Results: All doses of the extract significantly (p<0.05) reduced carrageenan-induced paw oedema, however the 400 mg/kg dose gave a sustained effect. The extract significantly inhibited xylene induced ear oedema at all doses. There were no significant (p>0.05) reductions in paw swellings due to formalin. In the acetic acid induced writhing test, the extract significantly (p<0.05) decreased writhing at 400 mg/kg only. Reaction times were not significantly different from the control in the hot plate and tail flick tests. Conclusion: This study has shown that the methanol extract possesses acute anti-inflammatory and peripherally mediated analgesic effects.

Summary Introduction: Hop (Humulus lupulus L.) is a common plant in Europe, with many beneficial health effects. In addition to the use in brewing, hops are a valuable source of active substances used in conventional and folk medicine, such as humulones and lupulones, as well as antioxidants, including phenolic compounds. Objective: The aim of the study was to evaluate and compare the antioxidant activity of alcoholic extracts of fresh hop leaves collected in 2017 and 2018. Material and methods: The raw material consisting of fresh hop leaves was extracted using ultrasound-assisted extraction. Methyl, ethyl and isopropyl alcohol at three concentrations were used as extractants. The antioxidant activity of extracts was determined using DPPH and FRAP methods. Total phenolic content was evaluated using the Folin-Ciocalteu technique. Results: All the extracts showed antioxidant potential as well as the phenolic content. Regardless of the harvesting year and methods of evaluation, the highest antioxidant activity and the total polyphenol content were observed for extracts prepared in undiluted methanol, obtained during one hour lasting extraction. Conclusion: The results of the studies have suggested that hop leaves can be a potential source of health-promoting antioxidants.

Summary Fireweed (Epilobium angustifolium L., Onagraceae) is one of important medicinal plants used especially in the treatment of urogenital disorders, including benign prostatic hyperplasia (BPH) and prostatitis. The therapeutic effects of E. angustifolium extracts comprise antiproliferative, anti-inflammatory, immunomodulatory, antioxidant, and also antimicrobial activities. The aim of the present review was to provide the information on the botany, phytochemistry and traditional uses of E. angustifolium. This plant is a widespread circumboreal species of North America and Eurasia, tolerant in terms of habitat conditions, and often occupying man-made open habitats. Phytochemical studies on E. angustifolium resulted in the identification of about 250 different metabolites, including about 170 substances found for the first time in this plant in the last six years (2014–2019). Fireweed has an abundance of polyphenolic compounds, particularly ellagitannins. Oenothein B and quercetin-3-O-glucuronide are proposed as markers for the identification and standardization of the plant raw material. E. angustifolium exhibits significant phytochemical variability in relation to the geographical origin, plant part and time of harvest/vegetation phase. Survey of the ethnobotanical literature showed that the above-mentioned species has been widely used not only as a medicinal, but also as an edible, honey and decorative plant.
火麻(Epilobium angustifolium L.,Onagraceae)是一种重要的药用植物,尤其用于治疗泌尿生殖系统疾病,包括良性前列腺增生(BPH)和前列腺炎。番荔枝提取物的治疗作用包括抗增殖、抗炎、免疫调节、抗氧化和抗微生物活性。本综述的目的是提供有关狭叶藻的植物学、植物化学和传统用途的信息。这种植物是北美洲和欧亚大陆广泛分布的环北方物种,在栖息地条件方面具有耐受性,经常占据人造的开放栖息地。对狭叶番荔枝的植物化学研究鉴定了约250种不同的代谢产物,其中包括过去六年(2014-2019)首次在该植物中发现的约170种物质。火苗中含有丰富的多酚类化合物,尤其是鞣花素。本研究提出了以催芽素B和槲皮素-3-O-葡萄糖醛酸苷作为植物原料鉴定和标准化的标志物。E.angustifolium在地理起源、植物部位和收获/植被阶段的时间方面表现出显著的植物化学变异性。对民族植物学文献的调查表明,上述物种不仅被广泛用作药用植物,还被广泛用作食用、蜂蜜和装饰植物。
