Keywords: | Betonica;Chemosystematics;Flavonoid glycosides;Lamiaceae;Stachys;Tricetin 3 ,4 ,5 -trimethyl ether 7-O-β-glucopyranoside;Tricetin derivatives | Issue Date: | 1-May-2004 | Journal: | Phytochemistry | 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-β-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. © 2004 Elsevier Ltd. All rights reserved. |
