Iridoids from Scutellaria albida ssp. albida

Abstract

Three iridoid glycosides, 6′- O- E- p-coumaroylgardoside ( 1), 6′- O- p- E-coumaroyl-8- epi-loganic acid ( 2) and scutelloside ( 3) were isolated from the aerial parts of Scutellaria albida subsp. albida, in addition to an anomeric mixture in equilibrium of one iridoid aglycone ( 4, 4a), nine iridoid glycosides ( 5– 13), four known phenylethanoid glycosides ( 14– 17), and six known phenolic derivatives ( 18– 23).
