Chemical Composition and Bioactivity of Reinw. Extracts on the Larval and Pupal Stages of .

AIMS AND OBJECTIVES

This study sought to investigate the chemical composition, larvicidal, and cytotoxic potentials of the fruit extract of Reinw.

MATERIALS AND METHODS

The chemical composition was analyzed using the gas chromatography-mass spectrometry technique. Separately, mortality data were evaluated by probit analysis to determine the lethal concentration (LC) and LC values on brine shrimp and larvae. Moreover, the effects on different stages of were also examined.

RESULTS

Fourteen majority components representing carboxylic acid were identified. The extract was very toxic to both brine shrimp and larvae with LC values of 0.308 and 0.514 µg/mL, whereas the LC values were 4.317 and 1.921 µg/mL, respectively. The effect of the fruit extract of on different stages of indicated that high concentrations (2.00-4.00 µg/mL) promoted complete mortality. A concentration of 0.125 to 1.00 µg/mL inhibited larval metamorphosis.

CONCLUSION

To the best of our knowledge, this is the first study to evaluate the chemical composition and larvicidal effects of the fruit extract of . The results indicate that the extract may be a promising source of larvicidal compounds that could be useful for pharmaceutical applications.
