Abstract

The invention relates to a method for enriching and purifying mangiferin from gentiana rhodantha and a detection method thereof. Orthogonal test design and a macroporous resin adsorption purificationtechnology are adopted. Dynamic adsorption and desorption purification process parameters of mangiferin are optimized. An HPLC method is used as a detection means; according to the present invention,the influence of the D101 type macroporous adsorption resin on the mangiferin purification effect is discussed, and the method has characteristics of stability, feasibility and simple operation, is suitable for the enrichment and the purification of the mangiferin in the gentiana rhodantha, can provide the reference for the future biological activity research and the product development and utilization, and is suitable for the future industrial production of the gentiana rhodantha mangiferin.

Description

technical field [0001] The invention relates to the field of separation, purification and detection of active components of traditional Chinese medicines, in particular to a method for enriching and purifying mangiferin from Gentiana safflower and a detection method thereof. Background technique [0002] Safflower gentian (Gentiana rhodantha Franch.), also known as small herring gall grass, is a perennial herb of the family Gentianaceae Gentiana. It is a species recorded in the 2015 edition of "Chinese Pharmacopoeia" and the local standards of Guizhou, Sichuan and Hunan. [1-6] . The whole herb is used as medicine, with a bitter and cold taste. It has the effects of clearing heat and dehumidification, detoxifying and purging fire, and relieving cough. It is often used clinically to treat damp-heat jaundice, lung-heat cough, bronchitis, etc. [7] . Through literature review and analysis, safflower gentian is one of the plants with high mangiferin content, and has good anti-ox...
