Distribution of Flavonoids and Stilbenoids of Coniferae Leaves

Abstract

Methanol extract of over 100 kinds of Coniferae plants was examined by paper chromatography for the presence of flavonoids and stilbenoids, and it was found that quercetin and kaempferol were distributed widely in this family. Myricetin, isorhamnetin, and taxifolin were detected and these were assumed to be present mainly as a glycoside. It was also confirmed that resveratrol is distributed in some of the Picea and Abies spp.
