Abstract

ETHNOPHARMACOLOGICAL RELEVANCE:

The species Acmella oleracea (L.) R.K. Jansen (Asteraceae), popularly known as jambú, is marketed in fairs as a female aphrodisiac and has several pharmacological activities already confirmed, among them the sexual stimulant action. The objective of this study was to evaluate the effects of the oral administration of the hydroethanolic extract of A. oleracea flowers (EHAo) on wistar rats during the pre-mating, mating, and pre-implantation period.

MATERIAL AND METHODS:

During the treatment period, measurements of feed intake, water intake, weight, estrous cycle, behavior, reproductive parameters, biochemical parameters, hematological parameters, and histopathology of ovaries were performed daily.

RESULTS:

In the gas chromatography analysis - mass spectrometry characterization, the compound (2E, 6Z, 8E) -N-isobutyldeca-2,6,8-trienamide (spilanthol) was detected as the majority compound at the 84% concentration. In the conditions of this study, EHAo did not cause maternal toxicity. However, in the estrous cycle, the frequency of the Proestrous (P) and Estrous (E) phase was significantly increased with the doses of 88.91 and 444.57mg/kg of the EHAo in relation to the control. On the other hand, the metaestrous (M) and diestrous (D) phases showed a significant reduction in their frequency in the groups treated with EHAo. Water intake increased significantly (p < 0.01), as well as the triglyceride levels, the total cholesterol and fractions (p < 0.05), and the percentage of neutrophils (p < 0.05).

CONCLUSION:

It is concluded, therefore, that the treatment with EHAo, which is one of the forms popularly used, is safe in the concentrations and time of treatment studied as it is able to influence the estrous cycle without altering folliculogenesis and fertility.
