Percent mortality of extracts of ethyl acetate and n-hexane.

Dose (µgml−1)	% Mortality
	Ethyl acetate	n-Hexane	Negative control
100	45 ± 0.42 c	50 ± 0.63 c	0
500	70 ± 0.33 b	85 ± 0.19 b	0
1000	85 ± 0.28 a	100 ± 0.77 a	0
LD50	151.5 µgml−1	92.22 µgml−1	–

All values are expressed as mean ± standard deviation (n = 3) p ≤ .05, LSD critical value for ethyl acetate 1.05 and 2.20 for n-hexane.
