Abstract

The invention relates to a method for simultaneously separating quercetin-3-O-gentian diglucoside and kaempferol-3-O-gentian diglucoside from folium sauropi and belongs to the technical field of separation and purification of a compound monomer. According to the invention, the folium sauropi medicinal material is taken as a raw material, and the quercetin-3-O-gentian diglucoside and kaempferol-3-O-gentian diglucoside monomers are acquired according to the steps of ethanol extraction, concentration, macro-porous resin enrichment and elution, polyamide resin enrichment and elution, efficient preparation, liquid chromatography separation and product recycling. According to the invention, through mature processing steps and parameter conditions, the purities of the quercetin-3-O-gentian diglucoside and the kaempferol-3-O-gentian diglucoside in the product respectively reach above 99%; and meanwhile, the method is simple and convenient in operation and is high in separating efficiency, the raw materials are recyclable, and the quercetin-3-O-gentian diglucoside and kaempferol-3-O-gentian diglucoside monomers can be simultaneously separated and prepared in large batch and high purity.

Description

Technical field

[0001] The present invention relates to a method for separating and purifying plant compounds, in particular to a method for simultaneously separating quercetin-3-0-gentiobioside and kaempferol-3-0-gentiobioside from Gentiana leaves, belonging to Chinese medicine Technical field. Background technique

[0002] Dragon Leaf Sauropus rostratus It is a plant of the genus Euphorbiaceae, also known as Agave Leaf, Dragon Leaf Leaf, Dragon Leaf Leaf, and Niu'er Leaf. It is mainly distributed in Guangdong, Guangxi, Fujian and other places. It is native to northern Vietnam and cultivated in the Malay Peninsula. It has the effects of clearing heat and moisturizing the lungs, resolving phlegm and relieving cough. It is used to treat diseases such as lung heat, cough, excessive phlegm, dry mouth and constipation. The current reports on Longliye are limited to some preliminary discussions, and there are few studies on its chemical components and pharmacological activities. The...
