title: A flavonoid 8-C-glycoside and a triterpenoid cinnamate from Nervilia fordii.
abstract: One new flavonoid glycoside (1) and one new triterpenoid cinnamate (2) were isolated from Nervilia fordii. The structures of 1 and 2 were determined by extensive NMR and HRESIMS to be 7-O-β-d-glucopyranosylapigenin-8-C-β-d-glucopyranosyl-(1 → 2)-β-d-glucopyranoside and 24(S/β)-dihydrocycloeucalenol-3-(Z)-p-hydroxycinnamate, respectively.
