Abstract

The invention relates to a method for purifying panax notoginseng total saponins and a preparation of the panax notoginseng total saponins, and aims to provide a purifying method capable of preparing panax notoginseng total saponins with higher efficiency and higher purity and overcoming the defects of the prior art. The purifying method breaks through the conventional method for purifying the panax notoginseng total saponins; impurity removal, decolorization and enrichment of the total saponins can be effectively implemented by fully combining different purifying effects of macroporous resin, polyamide and active carbon; and the polyamide is filtered by one step of washing operation, so the process is simple, an organic solvent is saved and industrialized production is easily realized. The invention also comprises the medicinal preparation of the panax notoginseng total saponins, and the preparation can be prepared into power injection, injection, tablets or capsules.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine chemistry, and in particular relates to a purification method of Panax notoginseng saponins and a preparation thereof. Background technique [0002] Panax notoginseng is the dry root and rhizome of Panax notoginseng (Burk.) F.H.Chen. It is warm in nature, sweet in taste, slightly bitter, and enters the stomach meridian. Function cures mainly for removing blood stasis and stopping bleeding, reducing swelling and relieving pain. For hemoptysis, hematemesis, hematochezia, uterine bleeding, traumatic bleeding, chest and abdomen tingling pain, tumbling and swelling pain. Mainly produced in Yunnan Wenshan, Yanshan, Guangnan, Maguan and Guangxi Jingxi, Mubian, Baise and other places. [0003] Panax notoginseng contains a variety of ingredients, among which total saponins of notoginseng are the main active ingredients of notoginseng, which are mainly distributed in the roots and rhizomes of ...
