152APHRODISIAC ACTIVITY OF AQUEOUS ROOT EXTRACT OF WALTHERIA INDICA IN MALE WISTAR ALBINO RATSThe objective of the present study is to evaluate the sexual performance (aphrodisiac activity) of aqueous root extract of Waltheria indica on male Wistar albino rats and the effects was compared with reference control Sildenafil citrate. Male Wistar albino rats were divided in to 4 groups of 6 animals each. Aqueous root extract of Waltheria indica (250 & 500mg/kg body weight) were administered orally and its sexual performance was compared to the normal and reference control animals (Sildenafil citrate 4.5mg/kg body weight). The effect of Waltheria indica on sexual performance in male rats were observed by mount frequency, mount latency, intromission frequency, intromission latency, genital grooming and ano – genital sniffing. The data’s were analyzed using ANOVA followed by dunnetts’t’ test. Waltheria indica showed dose dependent increase in mounting frequency, intromission frequency, ano-genital sniffing and genital grooming and decrease in mount latency and intromission frequency as compared to control. The aqueous root extract of Waltheria indica showed comparable aphrodisiac effect with the reference control Sildenafil citrate. From the result it was concluded that, aqueous root extract of Waltheria indica exhibits aphrodisiac activity in male Wistar albino ratsbasky235@gmail.comResearch622016Vitex nefundo,Aphrodisiac,Mount frequency, Mount latency, Intromission frequency,Intromission latencyBaskaran K, Ranjani RDepartment of Pharmacology, Chengalpattu Medical College, Chengalpattu, Tamilnadu, India.,Department of Pharmacology, Chengalpattu Medical College, Chengalpattu, Tamilnadu, India.
