Abstract

A zanthoxylum armatum total alkaloids extract, and a preparation method and an application thereof are provided. The preparation method comprises the steps: (1) smashing roots, stems, leaves and fruits of zanthoxylum armatum, and sieving with a 20-100 mesh sieve to obtain a crude zanthoxylum armatum; (2) extracting the crude zanthoxylum armatum with ethanol in a concentration of 50%-95%, filtering to recover the ethanol, concentrating to obtain an ethanol extract, then adjusting pH to 1-5 with hydrochloric acid, sulfuric acid or other acid reagents, standing overnight, filtering, then adjusting pH of the filtered liquid to 9-12 with sodium hydroxide, aqua ammonia or other alkali reagents, and standing overnight; and then extracting by chloroform to obtain the total alkaloids extract. The extract is used for preparation of drugs for treating pain and inflammation.

Description

technical field [0001] The present invention mainly relates to the field of natural product chemistry, in particular to the application of the effective extract from the bamboo leaf pepper, especially the application in analgesia. Background technique [0002] bamboo leaf pepper ( Zanthoxylum armatum ) is a medicinal plant of the Rutaceae Zanthoxylum bungeanum, and its roots, stems, leaves, fruits and seeds are all used as herbal medicines.
