Hypercholesterolemia is a condition characterized by increased levels of total cholesterol in the blood. Pheophytin is the result of degradation of chlorophyll which is the dominant pigment in green tea, and has been shown to have the same antioxidant properties as - carotene. This study aims to determine the antihypercholesterolemia effect and effective dose of pheophytin isolates and acute toxicity tests to determine the safety level of pheophytin isolates. Antihipocolesterolemia test uses induction of high-fat feed that is a mixture of standard food, pork oil and quail egg yolk (16: 3: 1). While the acute toxicity test is carried out based on OECD 423, Clinical symptoms that arise for 3 hours are observed intensively. Histopathological examination data of liver and kidney organs were performed on day 14. Data obtained in the form of LD 50 and clinical symptoms that arise as well as histopathological results were analyzed qualitatively. Statistical test results of percent reduction in total cholesterol levels showed a significant difference between the negative control group and the pheophytin isolates of the three doses. This proves that pheophytin isolates can have antihypercholesterolemic effect with an effective dose of 10 mg/kgBW. Histopathological examination results of aorta and liver of rats showed that the higher the dose of pheophytin isolates, the lighter the degree of fatty acid. While the toxicity test results showed that the LD50 value of pheophytin isolates was more than 2000 mg / kgBW (non-toxic category). However, pheophytin isolate with LD50 is more than 2000 mg/kgBW which has shown the presence of pancreatic degeneration and hydropic degeneration, but necrosis has not occurred yet.
高胆固醇血症是一种以血液中总胆固醇水平升高为特征的疾病。叶绿素是绿茶中主要色素叶绿素降解的结果,已被证明具有与- 胡萝卜素。本研究旨在确定脱镁叶绿素分离株的抗高胆固醇血症作用和有效剂量,并通过急性毒性试验来确定脱镁卟啉分离株的安全性水平。抗脂肪胆固醇血症试验使用高脂肪饲料的诱导,高脂肪饲料是标准食品、猪肉油和鹌鹑蛋黄(16:3:1)的混合物。虽然急性毒性试验是根据OECD 423进行的,但对出现3小时的临床症状进行了集中观察。在第14天进行肝和肾器官的组织病理学检查数据。对以LD 50形式获得的数据、出现的临床症状以及组织病理学结果进行定性分析。总胆固醇水平下降百分比的统计测试结果显示,阴性对照组和三个剂量的脱镁叶绿素分离株之间存在显著差异。这证明脱镁素分离物在10mg/kgBW的有效剂量下可以具有抗高胆固醇血症的作用。大鼠主动脉和肝脏的组织病理学检查结果显示,脱镁叶绿素分离物的剂量越高,脂肪酸的程度越轻。毒性试验结果表明,脱镁叶绿素分离物的LD50值大于2000mg/kgBW(无毒类)。然而,具有LD50的脱镁叶绿素分离物超过2000mg/kgBW,这表明存在胰腺变性和积水变性,但尚未发生坏死。

Every plant available in the universe is not produced to be the part of biodiversity, but is also produced to obtain medicinal purposes. The medicinal value of the plant is due to the availability of various chemical compounds [1]. Since prehistoric time, the crude extract of plant is used to cure various diseases, although the biologically active components of the plant were unidentified [2]. In the present study the antibacterial activity is performed for various extracts of cerastium glomeratum. The plant cerastium glomeratum was collected from near kalpani river Mardan, Pakistan and was identified by lecturer Israr department of botany GPGC Mardan, Pakistan. The plant was dried under shade and grinded into powder form. The extraction process was done by using soxhlet apparatus, reflux condenser and maceration process using ethanol as a solvent. The extract was divided into different fractions of n-hexane, DCM, ethyl acetate and water. These four extracts were tested against gram positive (staphylococcus aureus) and gram negative (E.coli) bacteria using well diffusion technique. The water extract show a wide range inhibition zone against both gram positive and gram negative bacteria while n-hexane, DCM and ethyl acetate fractions show no zone of inhibition against bacteria. In effort to find new antibacterial compounds cerastium glomeratum seems to be a good plant for additional phytochemical studies.
宇宙中的每一种植物都不是为了生物多样性而生产的,而是为了获得药用目的而生产的。这种植物的药用价值是由于它含有多种化合物。自史前以来,植物的粗提取物就被用来治疗各种疾病,尽管植物的生物活性成分尚未确定。本研究对不同提取物的抑菌活性进行了研究。该植物来自巴基斯坦马尔丹kalpani河附近,由巴基斯坦马尔丹GPGC植物学系讲师Israr鉴定。这种植物在阴凉处晒干,然后磨成粉末。采用索氏装置、回流冷凝器和以乙醇为溶剂的浸渍法进行提取。将提取液分成正己烷、DCM、乙酸乙酯和水的不同组分。采用孔扩散法对四种提取物进行革兰氏阳性(金黄色葡萄球菌)和革兰氏阴性(大肠杆菌)的抑菌试验。水提物对革兰氏阳性菌和革兰氏阴性菌均有较宽的抑制区,而正己烷、DCM和乙酸乙酯部分对细菌无抑制区。在寻找新的抗菌化合物的努力中,肾小球铜是一种很好的植物化学研究对象。

Rumex nervosus belongs to the family of Polygonaceae,which is traditionally used in Ethiopia to treat various diseases. This prompted us to isolate bioactive compounds from the root of this plant. Ground root parts of Rumex nervosus were subjected to exhaustive extraction successively with petroleum ether and methanol.The solvent from each extract was evaporated under reduced pressure using rotavapour to obtain petroleum ether and methanol extract. Chromatographic purification of the methanol extracts by Column chromatography followed by Preparative Thin layer Chromatography using Chloroform: methanol (9.5:0.5) ratio gave a compound coded as RN-6. The structure of this compound 4-ethylheptyl benzoate was characterized as by means of 1H NMR, 13C NMR, UV and IR spectral data.
神经性Rumex nervous属于何首乌科,在埃塞俄比亚传统上用于治疗各种疾病。这促使我们从这种植物的根部分离出具有生物活性的化合物。分别用石油醚和甲醇对神经酸模的生根部位进行了详尽的提取。使用旋转蒸汽在减压下蒸发来自每种提取物的溶剂以获得石油醚和甲醇提取物。通过柱色谱法对甲醇提取物进行色谱纯化,然后使用氯仿:甲醇(9.5∶0.5)的比例进行制备薄层色谱法,得到编码为RN-6的化合物。通过1H NMR、13C NMR、UV和IR光谱数据对该化合物4-乙基庚基苯甲酸酯的结构进行了表征。

Caffeine (1, 3, 5-trimethylxanthine) is an active ingredient that is often added to analgesics drugs to teat headaches or reduce pain. This study aims to quantitatively analyze caffeine levels in tablet dosage forms by spectrophotometric methods and iodometric back titration. In the spectrophotometric method the measurement of caffeine levels was carried out using a maximum wavelength of 272 nm.The results of caffeine levels were found for bodrex drugs (50.87 ± 0.195 mg/tab), extra panadol (64.92 ± 0.579 mg/tab), saridon (51.38 ± 0.273 mg/tab) and paramex (46.78 ± 0.072 mg/tab). The purity percentage of caffeine was found in the range between 93.57-102.76%. While the iodometric back titration method was obtained for bodrex (48.04 ± 0.889 mg/tab), extra panadol (64.45 ± 0.697 mg/tab), saridon (43.38 ± 0.756 mg/tab) and paramex (42.36 ± 0.889 mg/tab) with a purity range of 84.73-99.15%.

Phytoestrogen is a group of compounds that can replace the estrogen function in the body. One of its roles was as anti-neuroinflammatory by inhibiting the microglia M1 polarity activation. Marsilea crenata Presl. is a plant that suspected to contain phytoestrogens. The aim of this research was to determine the metabolite profile of 96% ethanol extract of M. crenata using UPLC-QToF-MS/MS, and prediction the anti-neuroinflammatory activity of compounds with molecular docking. The 100 ppm of 96% ethanol extract in DCM and methanol were injected 5 µl each into the UPLC-QToF-MS/MS, and then analyzed by Masslynx 4.1 software to determine the compounds. The result of metabolite profiling shows a total 59 compounds in both DCM and methanol. Molecular docking was done with Autodock 4.2.6. After being analyzed, there are 3 compounds that are predicted to have activities similar to 17β-estradiol, they are prochlorperazine, 12-Aminododecanoic acid, and 1-methyl-2-[(4-methylpiperazin-1-yl)methyl]benzimidaol-5-amine hydrochloride. The results showed that the three compounds were predicted to be phytoestrogen compounds from M. crenata leaves, which have potential as anti-neuroinflammatory.

The study investigated the molluscicidal activities of chloroform/methanol (1:1) extract of Tetrapleura tetraptera and isolated Aridanin. It also developed useable particulate formulation of chloroform methanol extract and Aridanin and evaluated their molluscicidal activities. This is with a view to providing information on development of useable particulate formulations for the control of snail intermediate hosts of schistosomiasis. The plant material was extracted successively in n-hexane (100%), chloroform (100%), chloroform/methanol (1:1) and methanol (100%) respectively by maceration. Bioactivity-guided fractionation of chloroform methanol extract was performed using column chromatography to isolate the active compound, Aridanin. Particulate formulations of chloroform methanol extract and Aridanin were prepared by emulsion solvent evaporation method. Molluscicidal screening on adult and newly hatched Biomphalaria glabrata snails was evaluated according to WHO protocols. The blank polymer formulation, dechlorinated water and Niclosamide served as controls. The result showed that Aridanin demonstrated the highest molluscicidal activity on adult B. glabrata snails with 24 h- LC50 of 1.61 ppm. The chloroform methanol extract had an LC50 value of 23.00 ppm, while particulate formulation of Aridanin and chloroform methanol extract had LC50 of 13.40 and 170.60 ppm respectively. This study showed that newly hatched B. glabrata snails are less susceptible to molluscicides compared to adult snails (P
