title: Two new compounds from Potentilla multicaulis Bunge.
abstract: Two new compounds (triterpenoid saponin and heterocyclic compound), 2α,3β, 19α,23,30-pentahydroxyurs-12-en-28-oic acid-28-O-β-d-glucopyranosyl ester (1) and N-hydroxyl-hexahydroazepin-2,4-diones (2), with 11 known compounds, picein (3), (7S,8R)-dihydrodehydrodiconiferyl alcohol-9'-O-β-d-glucopyranoside (4), (+)-1-hydroxy-2-epipinoresinol-1-β-d-glucoside (5), (+)-1-hydroxypinoresinol-1-β-d-glucoside (6), (+)-1-hydroxypinoresinol-4'-β-d-glucoside (7), schaftside (6-C-β-d-glucopyranosyl-8-C-α-l-arabinosyl apigenin) (8), isoschaftside (6-C-α-l-arabinosyl-8-C-β-d-glucopyranosyl apigenin) (9), isorhamnetin-3-O-β-d-glucopyranoside (10), quercetin-3-O-β-glucuronide (11), 8-O-methylherbacetin-3-O-sophoroside (12) and kaempferol (13), were isolated from Potentilla multicaulis Bunge. The structure of the compounds was elucidated by chemical and spectral evidence.
