麝香草Thymus vulgaris L.在南欧、西亚和北非均有栽培,其甲醇提取物有多种生物活性,但主要作为食用的热水提取物的生物活性未见报道。作者发现该植物叶热水提取物具抗补体活性,并对其进行了精制和鉴定。该植物用甲醇于室温提取5次,过滤后残余物再用热水提取。热水提取物(TV-O)分别用30％、75％和95％乙醇沉淀。75％乙醇

Thymus vulgaris L. is cultivated in southern Europe, Western Asia and North Africa. Its methanol extract has many biological activities, but its biological activity as a hot water extract has not been reported. The authors found that the plant leaf hot water extract had anti-complement activity and was refined and identified. The plant was extracted 5 times with methanol at room temperature and the residue was extracted with hot water after filtration. The hot water extract (TV-O) was precipitated with 30%, 75% and 95% ethanol, respectively. 75% ethanol
