Flavonol glycosides from Mentha lavandulacea.
In addition to kaempferol 3-O-rhamnoside-7-O-glucoside, the methanol extract of the aerial parts of Mentha lavandulacea yielded three new flavonoids identified as kaempferol 3-O-glucosyl-(1-->2)-rhamnoside-7-O-glucoside (1), kaempferol 3-O-(6"'-p-coumaroylglucosyl)-(1-->2)-rhamnoside-7-O-glucoside (2) and kaempferol 3-O-(4"'-p-coumaroylglucosyl)-(1-->2)-rhamnoside-7-O-glucoside (3).
