Three new phenolic glycosides from the Tibetan medicinal plant Aconitum tanguticum

Three new phenolic glycosides, such as (Z)-sinapic acid-4-O-β-d-allopyranoside (1), 3,4-dihydroxyphenethoxy-8-O-β-d-[6-O-(4-O-β-d-glucopyranosyl)-feruloyl]-glucopyranoside (2), and 4-dihydroxyphenethoxy-8-O-β-d-[6-O-(4-O-β-d-glucopyranosyl)-feruloyl]-glucopyranoside (3) were isolated from the EtOH extract of whole plant of Aconitum tanguticum (Maxim.) Stapf. The structures of the new compounds were elucidated by spectroscopic methods, and the total (1)H NMR and (13)C NMR chemical shifts were assigned.
