Embodiment 1

[0014] Take 100g of Gastrodia elata, 60g of Pteris anthracnina, 50g of Saccharomyces chinensis, and 150g of Datian Jihuang, crush them, add 2L of 70% ethanol, and put them into a microwave extraction device for microwave extraction. The extraction power is 400-600W, and the extraction is performed twice. For 4-8 minutes each time, combine the extracts, concentrate, add to D101 macroporous adsorption resin column, elute with 50% ethanol, collect 5 times the column volume eluate, recover ethanol under reduced pressure, concentrate and dry to obtain microwave The extract is prepared into tablets with conventional auxiliary materials, each tablet is 0.4g.

Embodiment 2

[0016] Take 100g of Gastrodia elata, 60g of Pteris anthracnina, 50g of Saccharomyces chinensis, and 150g of Datian Jihuang, crush them, add 2L of 70% ethanol, and put them into a microwave extraction device for microwave extraction. The extraction power is 400-600W, and the extraction is performed twice. For 4-8 minutes each time, combine the extracts, concentrate, add to D101 macroporous adsorption resin column, elute with 50% ethanol, collect 5 times the column volume eluate, recover ethanol under reduced pressure, concentrate and dry to obtain microwave The extract is prepared into capsules with conventional auxiliary materials.

Abstract

The invention provides an extracting method of a plant composite containing gastrodia elata. The plant composite is prepared from the raw material herbs of 100 g of gastrodia elata, 60 g of pteris biaurita, 50 g of ageratum conyzoides and 150 g of lysimachia fortunei maxim. The plant composite is prepared by the adoption of the microwave extracting method, in this way, the content is greatly increased, and the usage amount is reduced. The invention further provides an application of the plant composite containing the gastrodia elata in preparation of medicine for restraining rat adrenal medulla pheochromocytoma PC12 cell proliferation.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine preparations, in particular to an extraction method and application of a plant composition containing Gastrodia elata. Background technique [0002] The plant composition containing Gastrodia elata is made from 100g of Gastrodia elata, 60g of Pteris anthracnose, 50g of red thistle, and 150g of Datian Jihuang as raw materials. The current extraction method is to add water and decoct twice, each time for 2-3 hours, Combine the decoctions, filter, condense into a thick paste, granulate, dry, compress into 1000 tablets, coat with sugar, and get ready. It can clear away heat and dampness, activate blood and regulate menstruation. [0003] In the prior art, there is no report on the use of microwave technology in the extraction and preparation of the plant composition containing Gastrodia elata, but the method of decocting in water is rough, backward, and has many impurities, which ...
