Abstract

Three new flavonoid glycosides, 3-O-[b-D-glucopyranosyl-(1!3)-(4-O-trans-p-coumaroyl)-a-L-rhamnopyranosyl-(1!6)- b-D-glucopyranosyl]-7-O-[b-D-glucopyranosyl-(1!3)-a-L-rhamnopyranosyl]kaempferol, 3-O-[b-D-glucopyranosyl-(1!3)-(4-Otrans- p-coumaroyl)-a-L-rhamnopyranosyl-(1!6)-b-D-glucopyranosyl]-7-O-[b-D-glucopyranosyl-(1!3)-a-L-rhamnopyranosyl]quercetin and 7-O-[b-D-glucopyranosyl-(1!3)-a-L-rhamnopyranosyl]quercetin were isolated from the aqueous extract of the aerial parts of Aconitum naviculare. Their structures were elucidated by spectral analysis (HRAPI-TOF MS, 1H, 13C NMR, HMQC, HMBC, DFQ-COSY, ROESY and TOCSY).
