Abstract

Nine species from the genus Stachys L. representing subgenera Stachys and Betonica were surveyed for flavonoid glycosides by means of HPLC coupled to diode-array detection and LC-APCI-MS. Those species belonging to subgenus Betonica were characterised by the presence of glycosides of tricetin methyl ethers, including a new derivative, which was isolated from S. scardica Griseb. and identified as tricetin 3',4',5' -trimethyl ether 7-O-beta-glucopyranoside by spectroscopic methods. This type of flavonoid was absent from species belonging to subgenus Stachys and can be considered as a chemosystematic marker for subgenus Betonica.

摘要

采用高效液相色谱-二极管阵列检测联用技术和液相色谱-大气压化学电离质谱法，对隶属于水苏属和药水苏亚属的9种植物进行了黄酮苷类成分的研究。隶属于药水苏亚属的植物的特征在于含有三麦黄酮甲醚苷，其中包括一种新的衍生物，该衍生物从斯卡尔德水苏中分离得到，并通过光谱方法鉴定为三麦黄酮3'，4'，5'-三甲醚7-O-β-吡喃葡萄糖苷。这种类型的黄酮在隶属于水苏亚属的植物中不存在，可以被视为药水苏亚属的化学分类学标记。
