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).
