肾茶的化学成分

Chemical Constituents from Clerodendranthus spicatus

从肾茶 (Clerodendranthusspicatus)的地上部分共分离了 19个化合物 ,分别被鉴定为 5 羟基 7,3′ ,4′ 三甲氧基黄酮 (1) ,鼠尾草素 (2 ) ,5 羟基 6 ,7,3′ ,4′ 四甲氧基黄酮 (3) ,泽兰黄素 (4 ) ,3′ 羟基 5 ,7,8,4′ 四甲氧基黄酮 (5 ) ,异橙黄酮 (6 ) ,黄芪苷 (7) ,异槲皮素 (8) ,咖啡酸 (9) ,对 -羟基苯甲醛 (10 ) ,对 -羟基苯甲酸 (11) ,原儿茶醛 (12 ) ,原儿茶酸 (13) ,3,4 二羟基苯酰甲醇 (14 ) ,迷迭香酸 (15 ) ,迷迭香酸乙酯 (16 ) ,秦皮乙素(17) ,neoorthosipholA (18)和β 谷甾醇 (19)。迷迭香酸和其它酚性化合物可能与该植物的抗菌、消炎的药效有着直接的关系。

The investigation of the chemical constituents of the aerial parts of Clerodendranthus spicatus (Thunb.) C.Y.Wu obtained the isolation of nineteen compounds.Their structures were determined as 5-hydroxy-7,3′,4′-trimethoxyflavone(1),salvigenin(2),5-hydroxy-6,7,3′,4′-tetramethoxyflavone(3),eupatrin(4),3′-hydroxy-5,7,8,4′-tetramethoxyflavone(5),isosinensetin(6),astragalin(7),isoquercetrin(8),caffeic acid(9),p-hydroxy-benzaldehyde(10),p-hydroxy-benzoic acid(11),protocatechuic aldehyde(12),protocatechuic acid(13),3,4-dihydroxyphenacyl alcohol(14),rosmanic acid(15),rosmanic acid ethyl ester(16),esculetin(17),neoorthosiphol A (18) and β-stiosterol(19).Rosmanic acid and others phenolic compounds may be related to the effects of antibacterial and antiinflammation.
