Abstract

A process for preparing hydroxyl carthamus tinctorius yellow color A comprises using dry carthanus tinctorius as raw material, using deionized water and water alcohol as extracting solution, passing through preliminary separating column and refining column, using deionized water and water alcohol as eluent, and then obtaining hydroxyl carthamus tinctorius yellow color A after frozen and dried, and the content can reach 85%-99%. The invention uses cheap material, no toxic and safe solution, and has simple technology, high carthamus tinctorius usage and low cost, which is suitable to the industrialized industry, and the extracting rate is 0.8%-1.5% according to different purify requests of hydroxyl carthamus tinctorius yellow color A for various applications.

Description

Technical field: [0001] The invention relates to a method for extracting active ingredients from medicinal plants, in particular to a preparation method for hydroxysafflower yellow A. Background technique: [0002] Safflower (Catthamus tinctotins L.) is an annual herb of Compositae, which has been cultivated and used for medicine for more than 2100 years in my country. Its dried tubular flowers are commonly used in traditional Chinese medicine, and have the effects of promoting blood circulation, removing blood stasis and relieving pain. It is often used clinically to treat uterine congestion, cardiovascular, thrombosis and other diseases, and also as an analgesic and anti-inflammatory agent. Hydroxysafflower yellow A is one of the currently recognized active ingredients of safflower. Pharmacological experiments have proved that hydroxysafflower yellow A can significantly improve hypoxia tolerance, dilate coronary arteries, increase coronary flow, and significantly inhibit ...
