黄芩为唇形科黄芩属植物的根,约有7种作黄芩入药,含多种黄酮类化合物,为传统的清湿热中药。五十年代初期对其药理研究发现有降压、解热、利尿等作用,但有许多报告不尽一致。八十年代以来,对其黄酮类成分从分子药理学方面有了较深入的研究,现概述于下。调节 cAMP 水平cAMP 在腺苷环化酶以 ATP 为底物催化下合成, Astragalus is the root of the plant Astragalus in the Labiatae family. There are about 7 species of Radix Astragali used as medicines and contain a variety of flavonoids, which is a traditional Chinese herb for dampness and heat. In the early fifties, its pharmacological studies found that there were antihypertensive, antipyretic and diuretic effects, but many reports were not consistent. Since the 1980s, there have been more in-depth studies on flavonoids from molecular pharmacology, which are summarized below. Regulation of cAMP levels by cAMP synthesis using adenyl cyclase catalyzed by ATP as substrate
