In vitro and in vivo aphrodisiac properties of Corchorus depressus Linn. on rabbit corpus cavernosum smooth muscle relaxation and sexual behavior of normal male rats
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE: Corchorus depressus Linn. has been used as an aphrodisiac in traditional Indian medicine to treat male sexual dysfunction and impotency.
AIM OF THE STUDY: The petroleum ether, chloroform, ethyl acetate, n-butanol and aqueous fractions of 95% methanol extract of Corchorus depressus were screened initially for their in vitro aphrodisiac activity on rabbit corpus cavernosum smooth muscle. The chloroform fraction (CDC) was found to be the most active and therefore investigated further on general mating behavior, libido and potency of normal male Wistar albino rats in comparison with the standard drug, Sildenafil citrate.
MATERIALS AND METHODS: Animals were divided into the following groups: Control, SC CDC 100, CDC 200, and CDC 400, who received saline, Sildenafil citrate or the chloroform fraction of Corchorus depressus at doses of 100, 200 or 400mg/kg b.wt., respectively. The route of administration for all the groups was oral dosing, which was once in a day for 45 days. To analyze the mating behavior, female rats with estrus phase were used.
RESULTS: The chloroform fraction of methanolic extract of Corchorus depressus significantly reduced ML, IL, PEI and III. There was a significant increase in the MF, IF and EL and serum testosterone levels throughout the study period. The potency test significantly increased erections, quick flips, long flips and total reflex. In vitro aphrodisiac activity was significantly higher in chloroform fraction at a…
