Background: Uvaria narum (UN) is known to have antipyretic, antimicrobial, anti-inflammatory and antimalarial properties. The antidiabetic properties of UN remains unexplored. The current study has been aimed at understanding the antidiabetic property of UN extract on an in vitro model using 3T3-L1 cell line. Materials\ and Methods: Methanolic extract of UN was prepared, and its cytotoxic effect on 3T3-L1 cells was assessed. Glucose uptake and glucose transporter 4 (GLUT4) translocation in 3T3-L1 cell line on treatment with the extract was evaluated against a standard drug, metformin. α-glucosidase and α-amylase inhibition activities of the extract were also assayed with acarbose as the standard drug. Results: Treatment with UN extract had no cytotoxic effect on the cells. UN extract showed a good percentage inhibition of α-amylase and α-glucosidase activities. UN extract showed 71.31\% inhibition and the control drug Acarbose exhibited 88.54\% inhibition in α-amylase activity. Furthermore, the extract showed 79.11\% inhibition when Acarbose exhibited 87.35\% inhibition in α-glucosidase activity. IC50 values were also determined. Further, on treatment with the extract, 75.49\% of 3T3-L1 cells took up glucose and 70.67\% had GLUT4 expression. Conclusion: UN extract enhances glucose uptake and GLUT4 expression, inhibits α-amylase and α-glucosidase activities, thereby demonstrating the antidiabetic properties in vitro.

Objectives: To evaluate the anxiolytic effect of Coriandrum sativum (CS) aqueous extract in mice. To compare the antianxiety activity of CS against standard drug diazepam (3 mg/kg). Materials and Methods: After obtaining Institutional Animal Ethics Committee approval, Swiss albino mice (18-25 g) of either sex were randomly divided into five groups of six animals each. Dried powder of CS leaves was boiled with distilled water, cooled, filtered, placed on a hotplate for complete evaporation, finally weighed and stored. The control group, test group, and standard drugs group received saline, CS extract (50, 100, and 200 mg/kg), diazepam (3 mg/kg), respectively, by oral feeding. The antianxiety effect was assessed by elevated plus maze (EPM) in mice. Results: In EPM, it implied that CS 50 mg/kg (Group III), 100 mg/kg (Group IV), and 200 mg/kg (Group V) significantly (P \< 0.001) increases the number of entries in open arms compared to control. The time spent in open arms also increased in all the doses of CS extract significantly. Conclusion: The current study demonstrates statistically significant dose-dependent antianxiety activity of CS leaves.
