    • -6 M) was used as a reference drug (89.24%).β-Glucuronidase inhibition assay: The effect of the plant extracts on activity of β-glucuronidase was studied using a method described by Demetrios (1998). One millimolar concentration of test sample (0.1 mL) in 0.1 M acetate buffer pH 7.4 for 5 min at 37 °C were preincubated with 0.8 mL of 2.5 mM p-nitrophenyl-β-d-glucopyranosiduronic acid and 0.1 mL of β-glucuronidase was added. The mixture was incubated for 30 min. Reaction was terminated by addition of 2 mL of 0.5 N NaOH. The reaction mixtures were observed spectrophotometrically at 410 nm. Salicylic acid (1 mM) was used as a reference compound (23.30%).COX-2 inhibition micro-titer assay: The reaction mixture of 100% initial activity wells contained 160 μL of assay buffer, 150 μL of heme and 10 μL of COX-2 enzyme solution. While the reaction mixture of inhibitor wells was comprised of 150 μL of assay buffer, 10 μL of heme, and 10 μL of enzyme COX-2, 10 μL of the test samples (1 mM). The plates were carefully shaken for 5 s and were incubated for 5 min at 25 °C. After 5 min incubation 20 μL of the colorimetric substrate solution was added to all the wells, followed by the addition of 20 μL of arachidonic acid to all the wells. The plates were shaken gently for few seconds and again incubated for 5 min at 25 °C. The absorbance of all the wells was read at 590 nm using Thermo make Automatic Ex-Microplate Reader (M 51118170). The COX-2 inhibition activity (%) was calculated using following formulaCOX- 2 inhibition activity (%) = frac(T, C) × 100where T = absorbance of the inhibitor well at 590 nm, C = absorbance of the 100% initial activity without inhibitor well at 590 nm.
