Chemical study of the latex, stems, bracts, and flowers of “Christmas flower” (Euphorbia pulcherrima) I

The latex, stems, bracts, and flowers of Euphorbia pulcherrima Willd were chemically studied. Each part was extracted separately with petroleum ether. All the extracts contained germanicol, β-amyrin, and pseudotaraxasterol. From the latex was obtained a new sterol, C24H40O, pulcherrol. From the extracts of the stems were isolated an octaeicosanol and β-sitosterol.
