FLAVONOID CONSTITUENTS OF STACHYS-AEGYPTIACA

Twenty-four flavonoids were isolated from Stachys aegyptiaca Pers. Twelve glycosides were identified as vicenin-2, lucenin-2, apigenin and luteolin 7-glucosides and 7-diglucosides, chrysoeriol 7-glucoside, isoscutellarein 7-allosyl(1 --> 2)glucoside, isoscutellarein 7-[6'''-acetylallosyl-(1 --> 2)glucoside, hypolaetin 7-[6'''-acetylallosyl-(1 --> 2)-3''-acetylglucoside] (newly reported), apigenin 7-[6'''-acetylallosyl(1 --> 2) glucosise] and luteolin 7-[6'''-acetylallosyl-(1 --> 2)glucoside]. Twelve aglycones were also isolated and identifed as apignin, luteolin, chrysoeriol, xanthomicrol, sideritiflavone(?), 5,4'-dihydroxy-6,7,8,3'-tetramethoxyflavone, 5-hydroxy-6,7,8,3',4'-pentamethoxyflavone, calycopterin, chrysosplenetin, 5-hydroxy-3,6,7,8,4'-pentamethoxyflavone, 5,3',4'-trihydroxy-3,6,7,8-tetramethoxyflavone and 5,4'-dihydroxy-3,6,7,8,3'-pentamethoxyflavone.
