摘要

This study aimed to evaluate the content and composition of proteins and mucilages of the roots and seeds of moghat (G. bruguieri), as well as the hypoglycaemic effect of the mucilages. The crude protein constituted 19.5% of the seeds, while it madeup 4.5% of the peeled dried roots. Glutamic acid, proline, leucine, phenylalanine, histidine and arginine were abundant in the protein of both plant parts; 72 and 83%, respectively. Valine, cysteine, methionine and lysine were detected only in seed protein. Molecular weights of the seed proteins were 50 000, 45 000 and 22 000. Moghat seeds contained 5.0% mucilage, while 15.75% and 29.60% were recorded in roots of 1- and 2-year-old plants, respectively. GLC investigation showed that both these plant parts contained rhamnose, xylose, mannose and galacturonic acid. Arabinose (1.8%) and glucuronic acid (14.6%) were present only in the seeds, while galactose constituted 33.7 to 34.5% of the root mucilage. Age of the roots was reflected in quantitative differences rather than qualitative ones. The root mucilages had remarkable hypoglycaemic activity, decreasing the blood glucose level in male Sprague-Dawley albino diabetic rats by 54.5% within 15 days.
