The extracts from the bark of and have been analyzed by using high pressure liquid chromatography/electrospray ionization mass spectrometry. For the first time in the bark of 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.
采用高效液相色谱/电喷雾电离质谱法分析了 和 的树皮提取物。首次在 种的树皮中检测到类黄酮 C-糖苷。根据其 [M-H] 和 [M+H] 离子的特征裂解模式，鉴定出三种类黄酮 C-糖苷，即芹菜素-6,8-二-C-葡萄糖苷（vicenin-2）、芹菜素-6-C-葡萄糖苷（异荭草苷）和白杨素-8-C-葡萄糖苷。考虑到类黄酮 C-糖苷广泛研究的生物活性，这些常见果树的树皮似乎是具有潜在医学或化妆品应用的有趣材料。
