Hydrocarbons and alcohols of Chamesyce canescens

Abstract

We have investigated the epigeal part of Chamesyce canescens, family Euphorbiaceae, collected in full-flowering period in the Tashkent oblast. The eomminuted plant material was extracted with chloroform. The yield of extractive substances was 5.99%, of which the acetone-soluble fraction amounted to 4.46% and the insoluble fraction to 1.53%. The acetone-insoluble fraction was heated with petroleum ether (bp 40-70°C). The fraction soluble in petroleum ether was passed through a column filled with alumina (length of the column 70 cm, diameter 3.4 cm). The column was eluted successively with petroleum ether, benzene, diethyl ether, acetone, and methanol.
