Trans-pterostilbene and its derivative 2,4-dimethoxy-6-hydroxyphenanthrene in the leaves of Parthenocissus tricuspidata

Abstract

Trans-pterostilbene, cis-pterostilbene and 2,4-dimethoxy-6-hydroxyphenanthrene were detected in the leaves of Parthenocissus tricuspidata (Siebold et Zuccarini) Planchon. It was recorded for this plant for the first time that in autumn, when the leaves change in colour, there is an increase in content of 2,4-dimethoxy-6-hydroxyphenanthrene (DMPH), which is a derivative of trans-pterostilbene.
