从西葫芦幼果中分离得到2-咖啡酰基-3-羟基-3-甲基丁酸-4‘-β-d-吡喃葡萄糖氧基-3’-羟基苄酯和2-咖啡酰基-3-羟基-3-甲基丁酸-4‘-β-d-吡喃葡萄糖氧基苯甲酯(瓜苷H和瓜苷T)。通过波谱分析确定了它们的结构。这些成分表现出较弱的抗氧化活性。
Two new phenolic glycosides, 2-caffeoyl-3-hydroxy-3-methylbutyric 4′-β-d-glucopyranosyloxy-3′-hydroxybenzyl ester and 2-caffeoyl-3-hydroxy-3-methylbutyric 4′-β-d-glucopyranosyloxybenzyl ester (citrulluside H and citrulluside T) were isolated from young fruits ofCitrullus lanatus. Their structures were elucidated by spectroscopic analyses. These constituents exhibited weak antioxidant activity.
