三七皂甙是三七的主要化学成价,系由Rb组和Rg组皂甙组成。本文对三七皂甙组分的镇痛作用进行了实验观察。实验材料三七总皂甙、三七皂甙Rb组和Rg组均由昆明植物研究所提供。Rb组主要含人参皂甙Rb_1及少量Rb_2,Rc和Rd;Rg组主要含人参皂甙Rg_1及少量Rg_2、Rf和两种三七新皂甙。实验时以生理盐水将三七总皂甙和Rb组配成所需浓度,Rg组以2％吐温-80生理盐水配制。 Notoginseng saponin is the main chemical cost of Panax notoginseng and consists of Rb and Rg saponins. In this paper, the analgesic effect of Panax Notoginseng saponins was experimentally observed. Experimental materials Panax Notoginseng, Panax Notoginseng Rb group and Rg group were provided by Kunming Institute of Botany. Rb group mainly contains ginsenoside Rb_1 and a small amount of Rb_2, Rc and Rd; Rg group mainly contains ginsenoside Rg_1 and a small amount of Rg_2, Rf and two kinds of panaxanovins. At the time of experiment, the total concentration of panax notoginseng saponin and Rb group was made into physiological saline, and Rg group was prepared with 2% Tween-80 physiological saline.
