二年多来,全国防治老年慢性气管炎研究工作取得了巨大的成绩,许多有较好临床疗效的中草药经深入研究其有效成分,发现多数属于黄酮类化合物,例如小叶楷杷祛痰有效成分小叶楷杷素即为槲皮素甙(Quercitrin)、槲皮素(Quercetin)、棉子素(Gossypetin)的混合物,满山红祛痰有效成分为杜鹃素(Farreol)等等。 Over the past two years, the national research on the prevention and treatment of chronic bronchitis in the elderly has achieved tremendous results. Many Chinese herbal medicines with good clinical efficacy have been studied in detail for their active ingredients and found that most of them belong to flavonoids, such as leaflets, which are effective components of lobules. Alizarin is a mixture of Quercitrin, Quercetin, and Gossypetin. The active ingredient of Radix Polygonatifolia is Farreol and the like.
