南美蟛蜞菊中的酚酸类化学成分

Phenolic Compounds from Wedelia trilobata (L.) Hitchc

摘要:

为了解南美蟛蜞菊[Wedelia trilobata (L.) Hitchc.]的化学成分, 从其全株中分离得到9 个酚酸类化合物。经光谱分析, 分别鉴定为6-乙酰基-7-羟基-2,3-二甲基色原酮 (1)、七叶内酯 (2)、丁香醛 (3)、5-羟甲基糠醛 (4)、对羟基苯甲酸 (5)、水杨酸 (6)、反式对羟基桂皮酸 (7)、咖啡酸甲酯 (8) 和反式咖啡酸 (9)。化合物1~8 为首次从该植物中分离得到。

Abstract:

In order to understand the chemical constituents of Wedelia trilobata (L.) Hitchc., nine phenolic compounds were isolated from the ethanol extract of its whole plants. On the basis of spectral data, they were identified as 6-acetyl-7-hydroxy-2,3-dimethylchromone (1), esculetin (2), syringaldehyde (3), 5-hydroxymethyl-2-furalclehyde (4), p-hydroxybenzoic acid (5), salicylic acid (6), trans-p-hydroxycinamic acid (7), methyl caffeate (8), transcaffeic acid (9), respectively. Compounds 1-8 were isolated from this plant for the first time.
