Abstract

Two new triterpenoidal saponins were isolated from the n‐butanolic extract of Stachys parviflora (Lamiaceae). Their structures were elucidated on the basis of spectral data as stachyssaponin A; 3β, 15α, 19α, 21β, 22α‐pentahydroxyolean‐12‐ene‐28‐oic acid 3‐O‐{α‐L‐rhamnopyranosyl‐(1 → 3)‐β‐D‐glucopyranoside}‐22‐O‐{α‐L‐arabinofuranosyl‐(1 → 3)‐β‐D‐glucopyranoside} (1) and stachyssaponin B; 2β, 3β, 15α, 21β‐tetrahydroxyolean‐12‐ene‐28‐oic acid 2‐O‐[α‐L‐arabinofuranoside]‐3, 21‐bis‐O‐[β‐D‐glucopyranoside] (2).
