Item Effect of Artocarpus heterophyllus and Asteracanthus longifolia on glucose tolerance in normal human subjects and in maturity-onset diabetic patients(Elsevier, 1991) Fernando, M.R.; Wickramasinghe, N.; Thabrew, M.I.; Ariyananda, P.L.; Karunanayake, E.H.Investigations were carried out to evaluate the effects of hot-water extracts of Artocarpus heterophyllus leaves and Asteracanthus longifolia whole plant material on the glucose tolerance of normal human subjects and maturity-onset diabetic patients. The extracts of both Artocarpus heterophyllus and Asteracanthus longifolia significantly improved glucose tolerance in the normal subjects and the diabetic patients when investigated at oral doses equivalent to 20 g/kg of starting material.Item A Preliminary investigation of the possible hypoglycaemic activity of Asteracanthus longifolia(Elsevier, 1989) Fernando, M.R.; Wickramasinghe, N.; Thabrew, M.I.; Karunanayaka, E.H.Investigations were carried out to confirm or otherwise disprove the view held by many Ayurvedic and other traditional medical practitioners in Sri Lanka, that Asteracanthus longifolia possesses hypoglycaemic properties. The effects of an aqueous extract of the whole plant on fasting blood glucose level and glucose tolerance were investigated using Sprague-Dawley rats. The results indicate that aqueous extracts of A. longifolia can significantly lower the fasting blood glucose level and markedly improve the glucose tolerance of the rats. The hypoglycaemic effect produced by a therapeutic dose (equivalent to 5 g/kg of starting material) was comparable to that produced by a therapeutic dose (15 mg/kg of tolbutamide. The magnitude of the hypoglycaemic effect was found to vary with the dosage administered and the storage time of the prepared extract.
