概要

論文の詳細を見る
Studies were conducted on the flavonoid compounds in the leaves of Lyonia ovalifolia DRUDE var. elliptica HAND.-MAZZ. collected from various places in Japan, by means of paper chromatography. The results showed that the plant may be grouped into the following three biochemical variants, 1, 2 and 3. 1) containing dihydroquercetin-3-rhamnoside, quercetin-3-rhamnoside and quercetin-3-galactoside. 2) containing quercetin-3-rhamnoside and quercetin-3-galactoside. 3) containing quercetin-3-galactoside. Table I shows where the leaves were collected, and Fig.1 and Fig.2 show their geographical distribution. The constituents in the wood are apparently independent from the place of growth. Asterisks in Table I shows where the wood specimens were collected. The amount of toxic substances and that of triterpenoid glycosides are apparently not related to those of flavonoids.
