Abstract

This study aims to determine the yields and free radical scavenging activity based on IC50 value of the extract and the fraction of Lagerstroemia speciosa Pers leaves. The leaves of L. speciosa were macerated using 96% methanol and then practioned using different kinds of solvent based on its polarity including n-hexane, ethyl acetate, and n-butanol. The result showed that the yield of methanol extract obtained from L. speciosa levaes was 5.45% of dried samples obtained, the fraction of n-hexane 19.12%, the fraction of ethyl acetate 4,7%, and the fraction of n-butanol 1.93%. Testing of antioxidant activity is performed with the 1,1-Diphenyl-2- Picryl Hydrazyl (DPPH) by spectrophotometry UV-Visible. Absorbanse measurement was conducted with spectrophotometry at the wave lenght of 516 nm. Data was analyzed with linear regresion to obtain value of IC50. The result of research showed that the extract and fractions of L. speciosa leaves have activity as an antioxidant with the IC50 value of methanolic extract L. speciosa leaves was 12.5 ppm, n-hexane fraction was 18.75 ppm, ethyl acetate fraction was 21.87 ppm, n-butanol was 8.37 ppm.

Abstract

Honey kelulut is derived from the kelulut bee (Trigona sp.), which is native to Kalimantan and belongs to the Trigona genus of stingless bees. The honey produced by the Trigona genus has a well-documented antibacterial property. Study objective accomplished. This text discusses the potent antibacterial action of kelulut honey. The antibacterial testing method employed is the well diffusion method, utilizing the bacterium Staphylococcus epidermidis as the test organism. An antibacterial test was conducted by measuring the diameter of the zone of inhibition against bacteria. The results were obtained from concentrations of 40%, 60%, 80%, and 100%. Then the resistance diameter was measured for each concentration. The most optimal outcomes were achieved in the antibacterial test using honey kelulut. The honey kelulut with an 80% concentration exhibited a medium resistance level of 10.2 mm, while the 100% concentration demonstrated a strong resistance level of 13.7 mm.

Abstract

Naphthalene derivative compounds named Eleutherol (1) and Eleutherol C (2) have been isolated from Bawang Tiwai Bulb Eleutherine bulbosa. We tested its cytotoxic activity against T47D breast cancer cells in vitro after isolating compounds 1 and 2 from the EtOH extract using conventional chromatography methods. Their chemical structures were elucidated based on spectroscopic analysis, including IR, HR-TOFMS, 1D, and 2D NMR, and by comparison to those related spectra previously reported. Compounds 1 and 2 were tested for their cytotoxic effects against T47D breast cancer cells and showed moderate cytotoxicity against T47D breast cancer cells with IC50 values of 117.15 and 80.21 µM, respectively, compared with cisplatin 24.07 µM.

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.
