Abstract

The invention provides an extraction method of a herbal composition containing herba andrographitis. The herbal composition is prepared from the following medicinal raw materials: 100g of herba andrographitis, 90g of hyptis suaveolens, 80g of maianthemum bifolium and 150g of desmodium triflorum by adopting a microwave extraction method, so that the content is greatly improved, and the usage is reduced. The invention further provides an application of the herbal composition containing herba andrographitis in preparation of medicines for inhibiting cell proliferation of ehrlich ascites cancer ECA of mice.

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 Andrographis paniculata. Background technique [0002] The botanical composition containing Andrographis paniculata is made from 100g of Andrographis paniculata, 90g of Cymbidium japonica, 80g of Maihecao two-leaf, and 150g of Sandianjincao as raw materials. The current extraction method is to add water and decoct twice, each time for 2-3 hours, and combine The decoction is filtered, concentrated into a thick paste, granulated, dried, compressed into 1000 tablets, coated with sugar, and can resist viruses. [0003] In the prior art, there is no report on the use of microwave technology in the extraction and preparation of plant compositions containing Andrographis paniculata. However, the method of decocting in water is rough, backward, and has many impurities, which leads to ...
