用高压液相色谱/电喷雾电离质谱法分析了乌梅和樱桃树皮的提取物。首次在李属树皮中检测到黄酮类C-糖苷类化合物。根据它们的[M-H](-)和[M+H](+)离子的特征裂解模式，鉴定了3个黄酮类C-糖苷，即芹菜素-6，8-二碳-葡萄糖苷(藜芦素-2)、芹菜素-6-C-葡萄糖苷(异维他辛)和白杨素-8-C-葡萄糖苷。考虑到黄酮类C-糖苷被广泛研究的生物活性，这些常见果树的树皮似乎是潜在的医疗或化妆品应用的有趣材料。
The extracts from the bark ofPrunus aviumandPrunus cerasushave been analyzed by using high pressure liquid chromatography/electrospray ionization mass spectrometry. For the first time in the bark ofPrunusspecies flavonoid C-glycosides have been detected. On the basis of the characteristic fragmentation patterns of their [M-H](-)and [M + H](+)ions, three flavonoid C-glycosides have been identified, namely apigenin-6,8-di-C-glucoside (vicenin-2), apigenin-6-C-glucoside (isovitexin) and chrysin-8-C-glucoside. Taking into account the widely studied biological activities of flavonoid C-glycosides, the barks of these common fruit trees seem to be interesting materials of potential medical or cosmetic application.
