Two monoterpene glycosides 1 and 2 were isolated from the fruits of Gymnocladus chinensis BAILLON (Leguminosae). On the basis of chemical and physicochemical evidence, these glycosides were characterized as (6S)-2-trans-6-α-L-arabinopyranosyloxy-2, 6-dimethyl-2, 7-octadienoic acid and (6S)-2-trans-2, 6-dimethyl-6-[3-O-(β-D-glucopyranosyl)-4-O-(2-methylbutyroyl)-α-L-arabino-pyranosyloxy]-2, 7-octadienoic acid.
从中国南木豆的果实中分离出两种单萜糖苷1和2。根据化学和物理化学证据,这些糖苷的特征被确定为(6S)-2-trans-6-α-L-阿拉伯吡喃糖氧基-2, 6-二甲基-2, 7-辛二烯酸和(6S)-2-trans-2, 6-二甲基-6-[3-O-(β-D-葡萄糖吡喃糖基)-4-O-(2-甲基丁酰)-α-L-阿拉伯吡喃糖氧基]-2, 7-辛二烯酸。
