Eight flavonoids were isolated and identified as vitexin and its glucoside (8-C-diglucosylapigenin), the 3-glucosides of kaempferol, myricetin, 3'-methylmyricetin and syringetin, the 3-rutinoside of the latter and the 3-(p-coumaroylglucoside) of kaempferol. A great similarity was found in the flavonoid patterns of needle extracts of the Larix species hithertoo investigated.
