A new triterpenoidal saponin, stachyssaponin C (1), identified as 3β, 15α, 21β-trihydroxy-olean-12-ene-28-oic acid 3-O-[α-L-rhamnopyranosyl-(1→3)-O-6″-O-acetyl-β-D-glucopyranosyl-(1→2)-O-β-D-glucopyranoside] and a flavone glycoside stachyfloroside A (2), characterized as 5,8-dihydroxy-2-(3′-hydroxy-4′-methoxy)-7 [(6″”-O-acetyl-β-D-allopyranosyl-(1→2)-O-α-D-glucopyranosyl-(1→2)-O-β-D-glucopyranosyl)oxy]-4H-1-benzopyran-4-one, were isolated from the n-butanol extract of Stachys parviflora (Lamiaceae). The structures were elucidated by extensive spectroscopic (especially 2D NMR) experiments.
