The duration of estrous cycle together with that of various phase

The duration of estrous cycle together with that of various phases was determined. 10 The biochemical analysis in ovary and uterus of the treated rats were carried out to know the effect of flavonoid extract on the total protein content, total glycogen content and total cholesterol content of both organs. The total protein and cholesterol content of ovary and uterus were estimated by the method as described in Refs. 11 and 12 respectively. Results

are expressed as mean ± SD. The statistical analysis was carried out using one-way ANOVA analysis. The p-value of 0.05 or less was considered significant for all experiment. The qualitative test for flavonoids were performed and all the tests like Lead acetate test, Sodium hydroxide test, Sulfuric acid

test, Aqueous test were given positive by formation of yellow colored NVP-BKM120 purchase precipitation where in case of shinoda test has given positive by formation of pink selleck color. Over the study duration of 2–3 days, there were no deaths recorded in the experimental group of animals while giving the dose ranging from 100 mg/kg to 1000 mg/kg of b. w of ethanol extract of P. oleracea L. The animals did not show any change in general behavior, skin effecting, defecation, loss of hairs or other physiological activities. Hence, 250 and 500 mg/kg of b. w were fixed as low and high doses respectively to evaluate the anti-ovulation activity of ethanol extract of P. oleracea L. There is no significant change observed in the body weight of both low and high dose treated Linifanib (ABT-869) group animal when compared with control group. Daily oral administration of the ethanol extracts at both low and high

dose (250 and 500 mg/kg of b. w) significantly increased the weight of the uterus and ovary (761.66 ± 1.5275, 82.33 ± 3.0550) at high dose but moderate (343.33 ± 3.0550, 40.66 ± 2.0816) at low dose respectively, when compared with control (222.66 ± 2.5166, 31.33 ± 1.5275) as recorded (Table 1). The number of ova in the oviduct of high dose (500 mg/kg b w) treated rats was shown significantly reduced (2.5 ± 0.2), where in case of low dose (250 mg/kg b. w) has shown moderate (5.7 ± 1.1) after commencement of treatment (p ≤ 0.05) when compared with control (8.1 ± 3.2) as recorded ( Fig. 1). The oral administration of the ethanol extract of P. oleracea L at 250 mg and 500 mg/kg body weight caused a significant decrease in the uterine weight (92.66 ± 2.5166, 74.33 ± 3.7859) in immature rats when compared to control (172.33 ± 2.3094) as represented in ( Table 2). The treatment also altered the estrous cycle significantly characterized by a prolongation of the diestrous phase. The four phases of estrous cycle observed under the microscope reveal that a positive estrous smear is one in which only large, irregular cornified cells are seen indicating maximum growth of the vaginal mucosa.
