Two new unusual monoterpene glycosides, (Z)‐3,6‐dimethyl‐3‐(β‐D‐O‐glucosylmethylene)cyclohept‐4‐ene‐1‐one (1) and 3,6‐dimethyl‐3‐(β‐D‐O‐glucosylmethylene)cycloheptanone (2) have been isolated along with five known compounds, 3‐hydroxy‐4‐methoxybenzoic acid, 6,7‐dihydroxycoumarin, luteolin, apigenin 5‐O‐αl‐L‐rhamnoside, and pinocembrin‐7‐O‐rutinoside from ethyl acetate extract of Euphorbia decipiens
两种新的不寻常的单萜糖苷,(Z)-3,6-二甲基-3-(β-D-O-葡糖基亚甲基)cyclohept-4-ene-1-one (1) 和 3,6-二甲基-3-(β -D-O-葡萄糖基亚甲基)环庚酮 (2) 已与五种已知化合物、3-羟基-4-甲氧基苯甲酸、6,7-二羟基香豆素、木犀草素、芹菜素 5-O-αl-L-鼠李糖苷和松香素一起分离来自大戟属植物乙酸乙酯提取物的-7-O-芸香苷。通过广泛的 1D 和 2D NMR 以及质谱分析阐明了分离化合物的结构。版权所有 © 2011 John Wiley & Sons, Ltd.
