1H-NMR(DMSO- d 6 ,600MHz)谱(表1)显示,该化合物含有一对反式双键 δ7.56(1H,d, J=16.2Hz),6.39(1H,d, J=16.2Hz)和AB系统芳香氢 δ7.55(2H,d, J=8.4Hz),6.79(2H,d, J=8.4Hz),氢谱化学位移为4.52(1H,d, J=7.8Hz),推测为糖的端基氢。
13C-NMR(DMSO- d 6 ,150MHz)谱(表1)显示,该化合物含有两个共轭的羰基碳( δ C :168.4,167.2)和两个明显片段, δ C :116.2(2C),130.8(2C),160.2应为对羟基苯基片段, δ C :99.3,77.6,77.1,73.6,70.4,61.6为葡萄糖基片段。
通过HMBC,双键 δ H 7.56、6.39与苯基碳 δ C 125.5相关,双键 δ 6.39和-CH 2- δ H 4.12均与羰基 δ C 167.2相关,以上片段与其它C、H化学位移无相关,推测该片段为独立片段对羟基肉桂酰基,剩余部分除去糖基片段推测为母核。经过计算,母核不饱和度为4(含有一个羰基和双键),推测该母核为双环结构。通过HSQC、HMBC归属并连接,推测该化合物为环烯醚萜类化合物,进一步通过文献检索,确定该化合物母核为adoxosidic acid。
可知剩余片段为对羟基肉桂酸,与母核adoxosidic acid的10位成酯。通过SciFinder和Reaxys数据库检索,确定该化合物为新化合物(本实验中该化合物构型尚未确认,将在后续研究中进行确认),为10- O-( p-hydroxycinnamoyl)-adoxosidic acid。
