a Effects of chloroform fraction of methanolic extract of L. Siceraria fruits (CFMLS) and diazepam on the time mice spent in the open and closed arms. Values are expressed as mean ± SEM (n=6); ** p<0.01; *** p<0.001 compared with control (one way ANOVA followed by Student Newman Keuls test). b Effects of chloroform fraction of methanolic extract of L.
