Two flavanone glycosides were isolated from the aerial part of Launeae arborescens (Asteraceae), which were identified as hesperidin and naringin. They are the most abundant flavonoids in the edible parts of many species of citrus fruits. In this study, we were interested in the chiral separation and determination of the diastereomerisation barriers of hesperidin and naringin by HPLC methods. The chiral
从月桂(Laneae arborescens)(菊科)的空中部分分离了两种黄烷酮苷,它们被鉴定为橙皮苷和柚皮苷。它们是许多种类的柑橘类水果可食用部分中最丰富的类黄酮。在这项研究中,我们对手性分离和通过HPLC方法测定橙皮苷和柚皮苷的非对映异构化障碍感兴趣。的手性分离的HPLC筛选通过HPLC方法橙皮苷和柚皮苷的非对映体是在使用11个手性固定相和各种正相模式完成ñ正己烷/醇流动相。非对映异构的速率常数和活化能(ΔG在Chiralpak IC和Chiralpak IA上分别测定了黄烷酮,柚皮苷和橙皮苷的含量。在Chiralpak IC上通过HPLC确认了月桂树丁醇提取物中分离出的黄烷酮分析。
