In Vitro Licicidal Activity of Different Roots and Leaves Extract of Enicostema axillare (Gentianaceae).

Enicostema axillare is well known for its anthelmintic and bacterial activity. In present study dried leaves and roots of Enicostema axillare were subjected to exhaustic sequential extraction with four solvent i.e.-hexane, chloroform, methanol and distilled water respectively. All four extracts were studied for in vitro licicidal activity using goat-lice Damalinia caprae (Trichodectidae) as experimental organism. Only n-hexane and chloroform fractions showed statistically significant licicidal activity (p value <0.001, n = 5). Decrease in mean time required to kill the lice was observed at concentration 1% w/w and 10% w/w when compared to 1% lindane solution.
