Description:
The present research was conducted to discover antimicrobial compounds in methanolic leaf extracts ofJatropha curcasandAndrographis paniculataand ethanolic leaf extract ofPsidium guajavaand the effectiveness against microbes on flower preservative solution of cut Mokara Red orchid flowers was evaluated. The leaves were analyzed using gas chromatography-mass spectrometry. A total of nine, 66, and 29 compounds were identified inJ. curcas,P. guajava, andA. paniculataleaf extracts, with five (88.18%), four (34.66%), and three (50.47%) having unique antimicrobial compounds, respectively. The experimental design on vase life was conducted using a completely randomized design with 10 replications. The flower vase life was about 6 days in the solution containing theP. guajavaandA. paniculataleaf extracts at 15mg/L. Moreover, solution with leaf extracts ofA. paniculatahad the lowest bacterial count compared toP. guajavaandJ. curcas. Thus, these leaf extracts revealed the presence of relevant antimicrobial compounds. The leaf extracts have the potential as a cut flower solution to minimize microbial populations and extend flower vase life. However, the activities of specific antimicrobial compounds and double or triple combination leaf extracts to enhance the effectiveness to extend the vase life need to be tested.
