title: Two novel compounds from Paeonia suffructicosa.
abstract: A new hexacyclic triterpenoid, mudanpinoic acid A (1), and a new gallic acid glycoside, mudanoside B (2), along with nine known compounds--benzoic acid, resacetophenone, paeoniflorigenone, beta-sitosterol, betulinic acid, oleanoic acid, quercetin, beta-sitosterol-beta-D-glucoside, and trans-caffeic acid stearyl ester-were isolated from the dried root cortex of Paeonia suffruticosa. The structures of the novel compounds were elucidated on the basis of spectral methods, and that of compound 1 was confirmed by X-ray crystallographic analysis.
