Effect of ethanolic extract of A. catechu on the duration of the different phases of estrus cycle in rats

Group	Treatment	Dose	Number of days spent in each phase
			Proestrus	Estrus	Metestrus	Diestrus
I	Control	2 mL	2.00 ± 0.26	3.50	4.50	5.00 ± 0.26
	(4% gum acacia)			(3.00, 4.00)	(3.75, 5.25)
II	Ethanolic extract	100 mg/kg	5.50 ± 0.50*	2.0 **	2.0 ****	4.83 ± 0.31
				(1.00, 3.00)	(2.00, 4.00)
III	Ethanolic extract	300 mg/kg	6.50 ± 0.43*	1.0 ***	2.0 ***	5.17 ± 0.31
				(1.00, 2.00)	(1.75, 2.25)
P value	One way ANOVA		<0.001			0.727
	Kruskal–Wallis H test			0.003	0.005

Values are mean ± SEM in proestrus and diestrus; Values are median (25^th, 75^th percentile) in estrus and metestrus; In estrus and metestrus, Bonferroni correction was done, P < 0.025 is considered as significant; n = 6 in each group;

^*P < 0.001 when compared with control;

^**P = 0.015 when compared with control;

^****P = 0.024 when compared with control.

^***P = 0.002 when compared with control;
