Latest research project of Trifolium extract

At present, the latest research projects of Trifolium repens mainly involve the research direction of chemical composition, toxicology, medicinal effect and so on Chemical constituents of Trifolium repens by Li Yingqi, Lu Wenchao, Yu Zhiguo unit: Shenyang Medical University It has been found that 4 compounds have been isolated from the petroleum ether extract of the aboveground part of Ilex Trifolium: Dandelion terpene ketone, dandelion terpene alcohol, β - sitosterol and ergosterol; 3 compounds have been isolated from the chloroform extract of Ilex Trifolium: 6 "-O- benzoylcarotene, carotene and β - sitosterol; 7 compounds have been isolated from the ethyl acetate extract of Ilex Trifolium Four compounds were identified, including β - sitosterol, kaempferol, quercetin and kaempferol-3-o-neohesperidin Long term toxicological study of Trifolium repens by Jiang Yuexian and Xu Aiwen unit: Zhejiang Academy of Medical Sciences According to the "food safety toxicology evaluation test" in the "technical code for inspection and evaluation of health food" (2003 Edition), the researchers found that in the 30 day feeding test of rats with Trifolium cyanum, no toxic symptoms were found in the experimental animals, and no abnormal pathological changes were observed in the gross anatomy and histology The rats' body weight, food intake, food utilization rate, hemogram and blood biochemistry were all observed No significant effect In this experiment, it is concluded that Trifolium repens is safe and nontoxic (excerpted from Chinese Health Journal) experimental study on the medicinal effect of Trifolium repens extract Author: Huang Zhen, Mao Qingqiu, Wei Jiaping unit: Zhejiang University of traditional Chinese medicine, Zhejiang hospital of traditional Chinese Medicine The anti-inflammatory effect was observed by the methods of mice peritoneal capillary permeability, mouse ear swelling and rat foot swelling; the analgesic effect was observed by the methods of mice writhing and hot plate; the antipyretic effect was observed by the methods of dry yeast and 2,4 dinitrophenol The results showed that the extract had good anti-inflammatory, analgesic and antipyretic effects, which were consistent with the clinical efficacy and indications of TCM.
