  • n-Alkanes (n-nonacosane and n-hentriacontane), phytosterols (campesterol and ${\beta}$-sitosterol) and phytosteryl glucosides (${\beta}$-sitosterol 3-O-${\beta}$-D-glucopyranoside and campesterol 3-O-${\beta}$-D-glucopyranoside) were isolated from the underground parts of Epimedium koreanum (Berberidaceae) and characterized by spectral data.

  • S.deltoides (Compositae) distributed widely in Korea. China. It is edible as a food additive. but there has been no study on chemical constituents. Therefore. we isolated nine compounds from S.deltoldes. On the basis of spectroscopic evidence. the structure of these compounds were characterized as lupeol( 1), $\alpha$-amyrin(2).$\beta$-amyrin (3), ursolic acid(4), nonacosanol(5), nonacosanoic acid(6). mixture of $\beta$-sitosterol. stigmasterol and campesterol (7), $\beta$-sitosteryl-3-O-$\beta$-D-glucopyranoside(8), stigmasteryI-3-O-$\beta$-D-glucopyranoside(9).

  • One new sterol glucoside, $gomphsterol\;{\beta}-D-glucoside$ 1 along with known compounds, ${\beta}-sitosterol$, stigmasterol, campesterol, $stigmasterol-{\beta}-D-glucoside$, friedelin, 3-epi-friedelinol, allantoin, and $chrysoeriol-7-O-{\beta}-D-glucoside$ have been isolated from the aerial parts of Gomphrena globosa (Amaranthaceae). On the basis of spectroscopic (including 2D NMR) and chemical studies, the structure of 1 was elucidated as $(22E,24S)-24-ethylcholesta-7,9(11),22-trien-3{\beta}-ol-3-O-{\beta}-D-glucopyranoside$. Known compounds are reported for the first time from this plant species.
