Abstract

The invention provides a method for preparing Bailing tablets. The Bailing tablets are prepared from 194g of Chinese angelica, 42g of pseudo-ginseng, 83g of safflower, 167g of peony bark, 83g of peach kernel, 167g of divaricate saposhnikovia root, 167g of atractylodes, 42g of angelica root, 417g of purslane, 83g of red peony root and 194g of astragalus root serving as raw medicaments by adopting supercritical extraction and microwave extraction, so that the ferulic acid content is greatly improved. The invention also provides application of the Bailing tablets in preparation of a medicament for inhibiting propagation of human histiocytic lymphoma U937 cells.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine preparations, in particular to a preparation method and application of Bailing tablets. Background technique [0002] Bailing tablets are recorded in the standard WS3-B-0914-91 of the Ministry of Health, consisting of 194g of angelica, 42g of Sanqi, 83g of safflower, 167g of Moutan bark, 83g of peach kernel, 167g of Fangfeng, 167g of atractylodes, 42g of Angelica dahurica, 417g of purslane, 83g of Paeoniae Alba and 194g of Astragalus are made as raw materials, which can promote blood circulation and remove blood stasis, and increase photosensitivity. For Vitiligo. [0003] In the prior art, there is no report on the use of supercritical and microwave technology in the extraction and preparation of Bailing Tablets. However, the method of powdering and decocting in water is rough and backward, and there are many impurities, which leads to excessive dosage for patients and is in...
