title: [Study on the chemical composition of leaves and stalks of Trollius macropetalus].
abstract: A new constituent and four known compounds have been separated from the dry leaves and stalks of Trollius macropetalus Fr. Schmidt. By means of physico-chemical and spectroscopic methods, the structures of these compounds have been determined as vitexin-2''-O-beta-D-pyranxyloside (I), orientin-2''-O-beta-D-pyranxyloside (II), vitexin (III), orientin (IV) and 3-methoxy-4-hydroxyl-5-(3'-methyl-2'-)butylenzylbenzoic acid (V). I and II are found in the Trollius genus for the first time, V is a new compound named proglobeflowery acid.
