Abstract

Empirically, the three distinct color variants of M. speciosa leaves (red, white, and green) vein are widely utilized and reported to possess varying therapeutic properties. This difference in efficacy is hypothesized to be a direct consequence of variances in their respective secondary metabolite profiles. Given the limited research comprehensively characterizing these metabolites and assessing the comparative antibacterial activity of the three variants, this study aimed to identify the secondary metabolite groups present in the red, white, and green vein leaves and determine their antibacterial activity against Salmonella typhi and Staphylococcus aureus. The methodology involved maceration extraction using 96% ethanol, followed by phytochemical screening and antibacterial testing via the agar well diffusion method across concentrations of 5%, 10%, 20%, and 40%. The negative control (96% ethanol) and positive control (chloramphenicol) were simultaneously utilized. The results confirmed that all three vein samples contained major secondary metabolite groups, including alkaloids, flavonoids, phenolics, saponins, and tannins. Differential antibacterial activity was noted: the red vein extract showed the highest efficacy against S. typhi, achieving an inhibition zone of 4.68mm at 10%, while the green vein extract was most effective against S. aureus, with an inhibition zone of 5.00 mm at 10%. These findings definitively demonstrate a difference in antibacterial potency across the M. speciosa vein variants, collectively affirming their significant potential for development as antibacterial active agents.

Abstract

ABSTRACT There are still some people who do not understand the difference between the expiration date (Expired Date/ED) and the drug usage limit (Beyond Use Date/BUD). BUD is the time limit for drug use after compounding or after the primary packaging is opened. This activity aims to increase public knowledge, understanding, and awareness regarding the importance of paying attention to the safe limit for drug use or Beyond Use Date (BUD), so that people can use drugs wisely, safely, and responsibly. The activity implementation method includes counseling, material presentation, distribution of leaflets or brochures, and filling out pre-tests and post-tests. The number of participants who took part in this activity was 26 people. The results of the health promotion activity at the Lempake Community Health Center, Samarinda City showed that the average knowledge of participants about Beyond Use Date before providing education was 31.92%, and increased to 88.08% after being given information. Thus, it can be concluded that this activity was successful in increasing public knowledge regarding Beyond Use Date in the Lempake Community Health Center area, Samarinda City.. Key words: Beyond Use date (BUD), Expired date (ED), Lempake Health Center Samarinda City

Abstract

In this research, 1H-NMR-based metabolomics assessed the metabolite profiles of two Nephelium species flesh, specifically Nephelium ramboutan-ake and Nephelium lappaceum. Our research findings indicate that the metabolite profile of N. ramboutan-ake is qualitatively identical, although numerically distinct from that of N. lappaceum. The PLSDA data indicate that N. ramboutan-ake possesses elevated concentrations of acetic acid, malic acid, GABA, and succinic acid compared to N. lappaceum. In N. lappaceum, alanine and glucose serve as the distinguishing metabolites. Additionally, the anticancer efficacy of two Nephelium samples was assessed. As a result, the anticancer properties of N. ramboutan-ake were superior to those of N. lappaceum. PLS analysis indicated that GABA exhibited the most positive connection with the anticancer activity of Nephelium samples. These results indicate that the higher GABA concentrations of N. ramboutan-ake have a beneficial effect on its anticancer activity.
