title: Chemical constituents from Dendropanax dentiger.
abstract: Nineteen compounds and an HPLC inseparable mixture, composed of compounds 20 and 21, were isolated from the leaves and twigs of Dendropanax dentiger (Harms ex Diels) Merr. Of these, syringin (1) is the most abundant, 6'-O-apiofuranosyl dendranthemoside A (16) is a new megastigmane glycoside, and 3-methoxy-D-mannono-1,4-lactone (21) is a new hexono-1,4-lactone. Their structures were elucidated based on NMR spectroscopic and MS analyses.
