The extracts from the bark of Prunus avium and Prunus cerasus have been analyzed by using high pressure liquid chromatography/electrospray ionization mass spectrometry. For the first time in the bark of Prunus species 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.

检测 Prunus avium L. 和 Prunus cerasus L. 树皮提取物中的黄酮 C-糖苷。

已经使用高压液相色谱/电喷雾电离质谱法分析了从李属和樱桃属的树皮提取物。首次在李属物种的树皮中检测到类黄酮 C-糖苷。根据其 [MH]− 和 [M + H]+ 离子的特征性碎裂模式，已鉴定出三种黄酮类 C-糖苷，即 apigenin-6,8-di-C-glucoside (vicenin-2)， apigenin-6-C-glucoside (isovitexin) 和 chrysin-8-C-glucoside。考虑到对类黄酮 C-糖苷的生物活性进行了广泛研究，这些常见果树的树皮似乎是具有潜在医学或美容应用价值的有趣材料。
