Über Inhaltsstoffe von Euphorbiaceae, 8. Mitt. [1]. Triterpenester und Triterpenalkohole aus Euphorbia biglandulosa Desf. / Constituents of Euphorbiaceae, 8. Comm. [1]. Triterpen Esters and Triterpen Alcohols from Euphorbia biglandulosa Desf.

Gioacchino Falsone and Claudia Schneider

Fatty acids and acetic acid esters of lanosterol and cycloartenol and triterpens alcohols were isolated from the latex of Euphorbia biglandulosa Desf. The triterpenesters were identified as (E,Z)-2,4-decadienoyllanosterol (1a), (E,Z)-2,4-octadienoyllanosterol (1b), (E,Z)-2,4-oc- tadienoylcycloartenol (2a), (2E,4Z)-2,4,6-decatrienoyllanosterol (1c), (2E,4Z)-2,4,6-deca- trienoylcycloartenol (2b), lanosterylacetat (1d) and cycloartenylacetat (2c) by IR-, 1H-NMR- and MS-spectroscopy and hydrolysis. The triterpens alcohols were identified as butyrospermol, cyclo­artenol, 24-methylencycloartanol and obtusifoliol.
