  • From the legumes of Albizzia julibrissin Durazzini (Leguminosae), a mixture of long-chain alcohols, ${\alpha}-spinasterol$, a mixture of acylated sterol glycosides and ${\alpha}-spinasteryl$ $3-O-{\beta}-D-glucoside$ were isolated. Two mixtures of long-chain alcohols and acylated sterol glycosides were characterized as 1-hexacosanol (major) and 1-tetracosanol, and $3-O-[6'-O-palmitoyl-{\beta}-D-glucosyl]-{\alpha}-spinasterol$ (major) and its 6'-O-stearoyl ester. All compounds were identified on the basis of spectral data and chemical reactions.

  • The chromatographic separation of MeOH extract of the aerial parts of Aster glehni (Compositae) led to the isolation of three sesquiterpenes, two sterols and four terpenes. Their structures were determined to be $\beta$-amyrin acetate (1), phytol (2), alismol (3), $\alpha$-tocopheryl quinone (4), $\alpha$-spinasterol (5), 10-O-methyl alismoxide (6), alismoxide (7), and 3-O-(6'-O-palmitoyl-$\beta$-D-glucosyl)-spinasta 7,22-diene (8) by physicochemical and spectroscopic methods . These compounds (1-8) were first isolated from the Aster glehni.
