The structures of five genuine furostanol glycosides isolated from Metanarthecium luteo-viride MAXIM. (Liliaceae) were determined on the basis of liquid secondary ion mass spectrometric (LSIMS) analysis including liquid secondary ion mass spectrometr

Feeding experiments with [1,2-13C2]acetate and [2-13C,2H3]acetate in suspension cultures of A. elliptica demonstrate that campesterol has C-26 (the pro-R methyl group at C-25) and C-27 (the pro-S methyl group at C-25) arising from C-6 and C-2 of meva

Reversed phase HPLC analysis of sterols of cultured cells of Amsonia elliptica showed that campesterol is the major sterol. Campesterol and its 24-epimer, dihydrobrassicasterol, were isolated from suspension cultures of A. elliptica incubated with l

Shionogi carcinoma 115 (SC115), an androgen-dependent mouse mammary tumor, rapidly loses its androgen responsiveness after androgen withdrawal. The growth of this tumor can also be stimulated by high doses of estrogen or glucocorticoid. In the presen

Migration of the hydrogen atom at C-24 of cycloartenol to C-25 from the Re-face of the double bond occurred in the biosynthesis of isofucosterol in cell cultures of Physalis peruviana fed [2-13C2H3]acetate and [1,2-13C2] acetate. This was verified by

Tissue cultures of Physalis peruviana incubated with l -[Me- 2 H 3 ]methionine incorporated a maximum of four deuterium atoms into sitosterol, and thus confirmed that sitosterol is biosynthesized through a 24-ethylidene intermediate in this plant. Is
