Carbohydrate, lipid, protein, and amino acid conitnts of chenopodium murale, cyperus alopecuroides, desmosta chya bipinnata, and tamarix nilotica as allergic plants

ABSTRACT

Rhamnose, xylose, arabinose, glucose, fructose, galactose, sucrose, and rhafinose as well as traces of cellobiose and galacturonic acid were identified [TLC] in 90% ethanol extract of Chenopodium murale, Cyperus alopecuroides, Desmostachya bipinnata and Tamarix nilotica. Water soluble polysaccharides were prepared by hot extraction of the 4 plants, the total extractable pectins were determined, and component sugars detected [TLC] after hydrolysis were found to be identical in the 4 plants and similar to those of the corresponding free sugar extractives except for the absence of sucrose, rhafinose, cellobiose and fructose. Crude protein percentage were determined in the 4 plants. Amino acids contents of the 4 plants were almost similar, and glutamic acid was found to be the major component. Lipoidal composition of the 4 plants was studied, fatty acids identified by GLC of the methylated saponifiable fractions revealed qualitative and quantitative variations between the 4 plants, but palmitic acid was the major component in all of the investigated plants. Alpha-amyrin and beta-sitosterol were isolated from the unsaponifiable fraction of C. alopecuroids
