Investigation of the free sugars and mucilage of euphorbia pseudocasts A. Berger and euphorbia pubica N.E.BR.

ABSTRACT

Free sugars of the aerial parts of Euphorbia pseudocactus and Euphorbia nubica were isolated. Identification was carried out by paper chromatography [PC] and gas liquid chromatography [GLC] which revealed the presence of arabinose, rhamnose, xylose, fructose, galactose, glucose and glucuronic acid in a ratio of [16 20 12 4 16 3 1] in E. pseudocactus, as well as arabinose, rhamnose, xylose, fructose, galactose, glucose, galacturonic acid and glucuronic acid were detected in a ratio of [2 1 14 5 2 18 2 1] in E. nubica. Mucilage of each plant was separately extracted by cold and hot methods and weighed. PC and GLC analysis of the mucilage hydrolyzates revealed the presence of arabinose, rhamnose, xylose, galactose, glucose, and galacturonic acid in different ratios in the four mucilage hydrolyzates of the two plants
