The structures of two new flavones isolated from Scutellaria rehderiana, named rehderianin I and viscidulin III, were revised 2', 5, 5'-trihydroxy-7, 8-dimethoxyflavone and 3', 5, 6', 7-tetrahydroxy-2', 8-dimethoxyflavone, respectively, based on a comparison with the synthesized flavones.
根据与合成黄酮类化合物的比较,修订了从黄芩中分离出的两种新黄酮的结构,分别命名为黄芩素 I 和黄芩素 III,即 2',5,5'-三羟基-7,8-二甲氧基黄酮和 3',5,6',7-四羟基-2',8-二甲氧基黄酮。
