Six flavonol glycosides characterised as myricetin 3-O-alpha-rhamnosyl-(1'''-->2'')-alpha-rhamnoside-3'-O-alpha-rhamnoside, 5'-O-methylmyricetin 3-O-[alpha-rhamnosyl (1'''-->2'')][alpha-rhamnosyl (1''''-->4'')]-beta -glucoside-3'-O-beta-glucoside, 5'-O-methylmyricetin 3-O-alpha-rhamnosyl (1'''-->2'')-alpha-rhamnoside 3'-O-beta-galactoside, kaemferol 3-O-rutinoside-7-O-rutinoside, myricetin 3-O-rutinoside-3'-O-alpha-rhamnoside, myricetin 3-O-beta-glucosyl (1'''-->2'')-beta-glucoside-4'-O-beta-glucoside together with two iridoid glycosides identified as 6,8-diacetylharpagide and 6,8-diacetylharpagide-1-O-beta-(3',4'-di-O-acetylglucoside) have been isolated from extract of Ajuga remota aerial parts. Also isolated from the same extract were known compounds; kaempferol 3-O-alpha-rhamnoside, quercetin 3-O-beta-glucoside, quercetin 3-O-rutinoside, 8-acetylharpagide, ajugarin I and ajugarin II.
