kadsura induta/二酸化ケイ素

OBJECTIVE To study the chemical constituents from the fruits of Kadsura marmorata. METHODS The chemical constituents were isolated and purified by chromatography on silica gel, Sephadex LH-20 column and HPLC. RESULTS 9 compounds were isolated and identified as 4,5-dihydroxy-3-methoxybiphenyl (I),

OBJECTIVE To study the dibenzocylooctadiene lignans from the stems of Kadsura heteroclita. METHODS Chromatographic separations of silica gel and semi-preparative HPLC were used. All of the structures were elucidated on the basis of spectroscopic analysis, including 2D-NMR and HR-MS

To study the chemical constituents of K. oblongifolia, silica gel column chromatography, MCI and Sephadex LH-20 were used to separate the 70% acetone extract of the stems of K. oblongifolia. The structures of the isolated compounds have been established on the basis of physicochemical and NMR

The plants of the genus Kadsura are widely distributed in China, South Korea, and Japan. Their roots and stems are traditionally used to treat blood diseases and pain. The main bioactive constituents of Kadsura longipedunculata comprise highly oxygenated triterpenoids. Schiartane-type

OBJECTIVE To study the chemical constituents of the roots and stem bark of Kadsura coccinea. METHODS Compounds were isolated by column chromatography on silica gel and Sephadex LH-20, and finally purified by prep-HPLC. Their structures were elucidated by extensive spectroscopic methods, including
