Abstract Two new flavonol glycosides characterized as quercetin 3-O--l-rhamnopyranosyl-(12)-[-d-glucopyranosyl-(13)--l-(4-O-trans-p-coumaroylrhamnopyranosyl)-(16)]--d-galactopyranoside-7-O--l-rhamnopyranoside (1) and kaempferol 3-O--l-rhamnopyranosyl-(12)-[-d-glucopyranosyl-(13)--l-(4-O-trans-p-coumaroyl rhamnopyranosyl)-(16)]--d-galactopyranoside-7-O--l-rhamnopyranoside (2), together with two known flavonol glycosides quercetin 3-O--l-rhamnopyranosyl-(12)- [-l-rhamnopyranosyl-(16)]--d-galactopyranoside-7-O--l-rhamnopyranoside (3) and kaempferol 3-O--l-rhamnopyranosyl-(12)-[-l-rhamnopyranosyl-(16)]--d-galactopyranoside-7-O--l-rhamnopyranoside (4), were isolated from the whole plant of Aconitum tanguticum (Maxim.) Stapf. The structures of the new compounds were elucidated by spectroscopic methods, and the total H-1 and C-13 NMR chemical shifts were assigned.
