Abstract

Through the experiments and researches on astrapterocarpan, it has been found for the first time that astrapterocarpan can prominently inhibit the T lymphocyte proliferation induced by concanavalin A (Con A), has an immunity inhibiting effect, and thus can be advantageously used to prepare immunity inhibiting drug.

Description

technical field [0001] The invention relates to the field of medicine, in particular to the use of astragalus pteroside in the preparation of immunosuppressants. Background technique [0002] Astragalus membranaceus is a traditional Chinese medicine that strengthens the spleen and replenishes qi. It has the functions of invigorating qi and solidifying the surface, diuretic and detoxification, draining pus, astringing sores and promoting granulation.
