Method for preparing hydroxyl carthamus tinctorius yellow color A

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

A kind of preparation method of hydroxysafflor yellow A Technical field: The invention relates to a method for extracting effective ingredients from medicinal plants, in particular to a method for preparing hydroxysafflor yellow A. Background technique: Safflower (Catthamustinctotins L.) is an annual herbaceous plant in the Compositae family. It has been cultivated and used for more than 2100 years in my country. The dried tubular flower is a commonly used traditional Chinese medicine, which has the effects of promoting blood circulation, clearing collaterals, removing 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. Hydroxysafflor yellow A is one of the effective ingredients of safflower currently recognized. Pharmacological experiments show that hydroxysafflor yellow A can significantly improve hypoxia tolerance, expand coronary artery, inc...
