Abstract

The invention relates to an automatic control method for separation and purification of ginsenoside Rd. The method adopts a reversed-phase high performance chromatographic column to separate and purify ginsenoside extract. An elution solvent is formed by mixing of ethanol and water, and the elution mode is constant flow velocity or variable flow velocity stable pressure elution, also the content of ginsenoside in the eluent is detected and an adsorption model is combined to adjust the elution parameters to complete elution separation, thus obtaining high purity ginsenoside Rg1, Rb1 and Rd, especially high purity ginsenoside Rd. The automatic control method for separation and purification of ginsenoside Rd provided by the invention has the characteristics of high ginsenoside separation purity, high separation efficiency, solvent saving, energy saving and consumption reduction, safety and environmental protection, improves the economic value of the product, and is conducive to large-scale production.

Description

technical field [0001] The invention relates to the field of reverse-phase column chromatography separation and purification process control of natural product intermediates, in particular to a reverse-phase high-efficiency column chromatography automatic control separation and purification method for ginsenoside Rd. Background technique [0002] Ginseng is a traditional precious Chinese medicinal material in my country. Ginsenoside is the main active ingredient of ginseng. It has the main physiological activity of ginseng. There are more than 50 kinds of ginsenoside monomers that are clearly known; the content in ginseng accounts for about 4%. , has the effects of promoting substance metabolism, improving human immunity, anti-tumor, anti-fatigue, and anti-aging. [0003] Ginsenoside Rd, as an important saponin in ginseng extract, has the function of specifically blocking receptor-dependent calcium ion channels, and has other monomeric saponins in renal function protection, i...
