Evaluation of antinociceptive, antihyperglycemic, and membrane stabilizing activities of Garcinia lancifolia Roxb

Abstract

This study was undertaken to examine the antinociceptive, antihyperglycemic, and membrane stabilizing activity with phytochemical screening of methanolic extract of Garcinia lanceifolia whole plant. The extracts were subjected to in-vivo antinociceptive, antihyperglycemic activity in laboratory animals and in-vitro membrane stabilizing activity. In peripheral antinociceptive activity, G. lanceifolia (400 and 200 mg/kg) exhibited significant (P < 0.001) inhibition of writhing with 59.15% and 49.30% respectively comparable to standard Diclofenac (54.92% inhibition). In central antinociceptive activity, the extract (400 and 200 mg/kg) exhibited significant analgesic activity having 78.31% (P < 0.05) and 89.95% (P < 0.01) elongation of reaction time respectively in 90 min after administration of sample comparable to the standard Morphine (708.99% elongation). In hypoglycemic activity, the extract (400 and 200 mg/kg) exhibit statistically significant (P < 0.001) antihyperglycemic activity compared to standard drug Glibenclamide (10 mg/kg) at different time interval. In membrane stabilizing activity assay, clearly evident that the methanolic extracts of G. lanceifolia were highly effective to prevent the lyses of erythrocytes induced by heat. The outcomes of the present study revealed that this plant possess noteworthy pharmacological activities that may be basis for further research to disclose feasible mode of action of the plant part.
