作者用生物活性检测方法作指导,从三七(Panaxpseudo-ginseng Wall.var.notoginseng(Burkill)Hoo & Tseng)中分离出止血活性成分,命名为Den-cichine,化学名称为β-N一草酰-L-α,β-二氨基丙酸(Ⅰ)。止血活性成分的生物检定法: 取体重15～20g雄性小白鼠腹腔给予0.5ml乐氏液。10分钟后,在固定器中固定,割开鼠尾中部左尾静 The authors used bioassay as a guide to isolate the hemostatic active ingredient from Panax pseudo- ginseng Wall.var.notoginseng (Burkill) Hoo & Tseng, named as Den-cichine with the chemical name β-N-oxalyl -L-α, β-diaminopropionic acid (Ⅰ). Bioassay for hemostatic active ingredients: Male mice weighing 15-20 g were given intraperitoneally 0.5 ml of Lecithin solution. 10 minutes later, fixed in the holder, cut off the middle tail tail left mouse tail
