meso dihydroguaiaretic acid/サネカズラ属

Two DNA cleavage agents, meso-dihydroguaiaretic acid (1) and isobavachalcone (2) together with the known alpha-ylangene, beta-sitosterol, daucosterol, pentacosane, hexacosanic acid and cerotic acid 1-monoglyceride were isolated from the stem barks of Kadsura ananosma Kerr for the first time.

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

To investigate the chemical constituents from stems of Kadsura longipedunculata. The constituents were isolated and purified by various chromatographic methods,and their structures were elucidated by spectroscopic analysis and comparison with literatures. Seven compounds were isolated from the stems

A new dibenzocyclooctadiene lignan named angustifolin D (1) together with four known lignans: kadsulignan L (2), kadsulignan N (3), schisantherin P (4) and meso-dihydroguaiaretic acid (5) were isolated from the stems of Kadsura angustifolia. Their structures and stereochemistries were elucidated by

Two new C(18) dibenzocyclooctadiene lignans named heteroclitalignans A and B (1 and 3), one new C(19) homolignan named heteroclitalignan C(4) and one new natural product named heteroclitalignan D(2), together with the four known lignans kadsurarin (5), kadsulignan E (6), d-epigalbacin, and

A new dibenzocyclooctadiene lignan, kadsutherin D (1), together with 12 known lignans, kadsurin (2), heteroclitin C (3), interiotherin C (4), schisanlignone A (5), binankadsurin A (6), angeloyl binankadsurin A (7), gomisin U (8), heteroclitin D (9), interiorin (10), schiarisanrin C (11),
