Abstract

The invention relates to a Lindera reflexa Hemsl ethylacetate part extract and an application thereof, which can effectively solve the problem of preparing drugs for curing and preventing chronic gastritis and gastric ulcer. The extract is prepared by the following steps: taking Lindera reflexa Hemsl root, crushing, sieving, refluxing and extracting Lindera reflexa Hemsl root powder for three times by petroleumether with a boiling point of 60-90 DEG, pumping and filtering, abandoning filtrate, refluxing and extracting for three times by ethylacetate, pumping and filtering, decompressing in vacuum and recovering ethylacetate, concentrating and drying at the temperature of 40-60 DEG C to obtain dry powder with the yield of 2.48%. The preparation method of the invention is simple and convenient, and the obtained effective part extract has stable quality, can be effectively used for preparing drugs for curing and preventing spleen-stomach deficiency-cold chronic gastritis and gastric ulcer, opens up a novel field for Lindera reflexa Hemsl to prepare drugs and is an innovation in traditional Chinese medicine and pharmacology.
