Percentage Antiprotease Activity of Aqueous Root Extract of L. cornuta

Concentration (µg/ml)	% Antiprotease activity ( $\overline{\mathit{x}}$  ± SEM)
	Aqueous root extract of L. cornuta	Standard (Indomethacin)
1	10.69  ±  0.42aC	10.40  ±  0.20aC
10	15.23  ±  0.18aB	14.56  ±  0.08bB
100	20.27  ±  0.39aA	14.91  ±  0.31bB
1000	21.42  ±  0.47aA	20.98  ±  0.41aA

Values are expressed as $\overline{x}\pm SEM$ ; Values with different lower-case superscript letters within a row (Unpaired student t-test) and different upper-case superscript letters within a column (One-Way ANOVA with Fisher’s LSD post hoc) are significantly different (p < 0.05).
