Three new phenolic glycosides from the Tibetan medicinal plant Aconitum tanguticum

Abstract

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 ¹H NMR and ¹³C NMR chemical shifts were assigned.

Keywords:
