黄芩甙(Baicalin,简称 HB)是黄芩的主要有效成分。近年来研究结果表明它对致敏豚鼠肺组织释放的组织胺及 SRS-A 物质有明显的抑制作用,能缓解动物过敏性哮喘。据报道锌剂对支气管哮喘也有一定疗效,而某些药物若转化为金属配合物,则有可能增强其疗效。
Baicalin (abbreviated as HB) is the main active ingredient of Astragalus membranaceus. Recent studies have shown that it has a significant inhibitory effect on the release of histamine and SRS-A substances in lung tissue of sensitized guinea pigs and can relieve allergic asthma in animals. It has been reported that zinc agents also have a certain effect on bronchial asthma, and certain drugs may increase their efficacy if they are converted into metal complexes.
