Potential Antidiabetic Activity of Extracts and Isolated Compound from Adenosma bracteosum (Bonati).

ABSTRACT: Adenosma bracteosum Bonati. (A. bracteosum) has been used in traditional and modern medicine in Vietnam for curing hepatitis. In this study, ethanol and aqueous extracts of A. bracteosum were evaluated for their ?-glucosidase inhibitory activities and anti-hyperglycemic effects on glucose loaded hyperglycemic and streptozotocin (STZ) induced diabetic mice. The ?-glucosidase inhibition of the extracts was evaluated by colorimetric assays, and the anti-diabetic activity was tested on a STZ-induced diabetic mice model. The ethanol and aqueous extracts showed a significant ?-glucosidase inhibitory activity, which was more effective than acarbose at the same concentration. In the STZ-induced diabetic mice, both extracts showed a strong anti-hyperglycemic activity, with the group receiving 50 mg/kg of ethanol extract and the group receiving 50 mg/kg of aqueous extract presenting 64.42% and 57.69% reductions, respectively, in the blood glucose levels when compared with the diabetic control group, on day 21 (p > 0.05). Isoscutellarein-8-O-?-D-glucopyranoside (IG) was identified from the ethanol extract, which showed a strong inhibitory activity against ?-glucosidase, with a ten times higher potency compared with the positive control acarbose. The anti-hyperglycemic effect of IG was effectively similar to the standard drug, glibenclamide, at the same dose of 10 mg/kg (p > 0.05). These results indicated that A. bracteosum has a great antidiabetic potential.

Adenosma bracteosum Bonati. (A. bracteosum) has been used in traditional and modern medicine in Vietnam for curing hepatitis. In this study, ethanol and aqueous extracts of A. bracteosum were evaluated for their α-glucosidase inhibitory activities and anti-hyperglycemic effects on glucose loaded hyperglycemic and streptozotocin (STZ) induced diabetic mice.

Project description:Diabetes mellitus is a chronic illness, and the management of diabetes is a global problem. Successful treatment is required to prevent complications and organ damages. Herbal medicines are having minimal adverse effects when compared to the available synthetic drugs to treat such chronic diseases and disorders.The present study was aimed to evaluate the antidiabetic and antioxidant activity of polar and nonpolar solvent extracts of Leucas aspera (Willd.) link leaves under in vitro models.The in vitro antidiabetic activity of petroleum ether (nonpolar) and ethanol (polar) extracts were evaluated in C2C12 cell lines by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay (cell viability method) and glucose uptake assay. 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging method used for the evaluation of in vitro antioxidant activity.Both the polar and nonpolar solvent extracts of L. aspera had shown better antioxidant activity compared to standard (IC50 = 18.96 and 19.90 μg/mL, respectively). Petroleum ether extract exhibited better cytotoxic activity in C2C12 cell line compared to ethanol extract (concentration of test drug needed to inhibit cell growth by 50% 110.75 ± 5.5 vs. 415.25 ± 8.0 μg/mL) whereas ethanol extract showed enhanced glucose uptake activity than petroleum ether extract in C2C12 cell line at same concentrations.From our study results, we concluded that L. aspera (Willd.) link leaves had shown better antidiabetic activity and antioxidant activity under in vitro models. Nonpolar solvent extract produced slightly better activity than polar solvent extract. This study warrants further research and experiments on animal models.Petroleum ether extract of Leucas aspera (PELA) exhibited slightly higher 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging activity compared to ethanol extract of L. aspera (EELA)PELA exhibited better cytotoxic activity in C2C12 cell line compared to EELAEELA had shown enhanced glucose uptake activity than PELA in C2C12 cell line at same concentrationsL. aspera leaf extracts have potential scavenging of DPPH radicals similar to that of ascorbic acidOverall, PELA (nonpolar) produced slightly better antidiabetic activity and antioxidant activity than EELA (polar).
