    摘    要

    In the course of a phytochemical and chemotaxonomical investigation for the Castanopsis (Fagaceae) species,fifteen compounds, including two triterpene hexahydroxydiphenoyl esters (1 and 2), seven gallotannins (3–9),three flavonoids (10–12), and three other compounds (13–15) were isolated from the leaves of Castanopsis fargesii Franch. Their structures were elucidated by means of spectroscopic methods and in comparison with published data. All these compounds were obtained from this species for the first time. Moreover, ethyl glucopyranoside (15) was firstly isolated from the genus Castanopsis. 6-O-Galloyl-β-D-glucose (3) and 3,4′,5,7-tetrahydroxyflavone(11) have not been reported from any species in Fagaceae family. The chemotaxonomic significanceof these compounds was summarized.
