Embodiment 1

[0027] Take 1.0kg of Yunnan medicinal materials (batch number: 131110), add 8 times the amount of 95% ethanol to reflux for extraction for 3 hours, extract 3 times, filter and combine the extracts, concentrate under reduced pressure at 60°C until there is no alcohol smell, add deionized water to 4L to make Dissolve, centrifuge, take D101 macroporous adsorption resin on the supernatant (1 kg of medicinal materials requires 300 ml of D101 resin pretreated by swelling with absolute ethanol), and the ratio of diameter to height of the resin column is 1:8. The flow rate is 1.0BV / h. After the sample is loaded, the elution flow rate is 5BV / h. First, use deionized water to elute 2BV of the resin column, discard the flow-through liquid and water eluent, and then use 85% ethanol to elute the resin Column 6BV, collect the eluate of 85% ethanol, concentrate under reduced pressure at 60°C, and dry to obtain 16.43g of the extract of Sagittarius japonica, batch number 131110, with a yield of ...

Abstract

The invention discloses a paederia scandens extract. The extract contains iridoid glycoside compounds, and is characterized in that the iridoid glycoside compounds are mainly composed of 20.0-50.0% of paederosidic acid, 2.0-25.0% of paederoside and 1.0-10.0% of paederosidic acid methyl ester. The paederia scandens extract is prepared by the following ways: a) extracting paederia scandens medicinal material by virtue of ethanol to obtain an extracting solution; b) concentrating the extracting solution until no alcohol smell exists, carrying out macro-porous adsorption resin chromatography, eluting with water and 80-90% of ethanol sequentially, collecting eluate, and drying the eluate under reduced pressure to obtain the paederia scandens extract. The paederia scandens extract disclosed by the invention is applicable to the preparation of medicines which are capable of reducing uric acid, and also resisting inflammation and gouty arthritis.

Description

technical field [0001] The present invention relates to an extract of vine vine and its use. Background technique [0002] Chicken Yateng is the above-ground part or whole plant of Rubiaceae Paederia scandens (Lour.) Merr.
