Abstract

The synthesis of methyl ester nitrate (MEN) from ketapang oil (Terminalia catappa L.) have been carried out. This study aims to determine the yield and the characteristics of MEN. In this study, ketapang seed oil was obtained from the soxhlet extraction process followed by an evaporation process to separate the oil from the solvent. MEN can be produced from ketapang seed oil by esterification to convert all of FFA became ester, followed by transesterification that intended to produce ester from triglycerides and nitrationthat is reaction of esther and HNO3 to create MEN. Evaporated oil is esterified using methanol with a mole ratio of oil: methanol (1: 6), then the transesterification process using methanol with a mole ratio (1:15) gives a yield of 86%. The transesterification product was then nitrated using HNO3 and H2SO4 for 4 hours with a yield of 83%. Characterization of methyl ester using GC-MS characterization showed the presence of methyl palmitoleate (C17H32O2), methyl palmitate (C19H34O2), methyl oleate (C19H36O2), methyl 13-octadecanoic (C19H36O2), methyl stearate (C19H38O2), and methyl 18-nonadecanoic (C21H42O2). Characterization MEN using a FTIR spectrophotometer showed the presence of a C-ONO2 group at wave number 1550 cm-1, NO2 group at wave number 1365 cm-1 and a C-N group at wave number 1118 cm-1. It shows that MEN can be synthesized from ketapang seed oil.

Abstract

Cleome viscosa L. has been used empirically by people on the island to treat diseases that have clinical symptoms such as malaria (fever, sweating, chills, and muscle aches). The purpose of this study was to determine the class of secondary metabolites and antioxidant activity. The extraction was carried out using the maceration method, while the fractionation was carried out using the separating funnel. The secondary metabolites found in the Cleome viscosa L. plant extract are alkaloids, flavonoids, steroids, terpenoids, tannins, and saponins. Antioxidant test conducted by DPPH method showed that the positive control of ascorbic acid and methanol extract obtained IC50 values of 3.86 ppm and 37.4 ppm, respectively.

Abstract

An antibacterial activity test against Staphylococcus aureus using henna leaf extract (Lawsonia inermis Linn.) has been conducted. This study aimed to determine the secondary metabolite components and the major compounds present in the henna leaf extract, as well as its inhibitory activity against Staphylococcus aureus. The secondary metabolite components were identified through phytochemical screening, while the major compounds were determined using GC-MS. The antibacterial activity was tested at concentration variations of 75%, 50%, 25%, and 12.5%. The resulting inhibition zones were then categorized according to standard criteria. The significance of the effect of concentration on the inhibition zones was analyzed using a one-way ANOVA test, followed by LSD test at α = 0.05. The results showed that the henna leaf extract tested positive for flavonoids, alkaloids, tannins, and quinones and GC-MS analysis shows compounds included 1,5-heptadiene-3,4-diol, 2-methyl-; 2-undecene, 2-methyl-; cyclotrisiloxane, hexamethyl-; 2,6-dihydroxyacetophenone; and 2,3-dihydroxybenzoic acid. The antibacterial activity test results showed that different concentrations (12.5%, 25%, 50%, and 75%) produced different inhibition zones; however, all were still classified within the same category, namely moderate. Statistical analysis indicates a significant effect of concentration on the inhibitory activity against the test bacteria, where F test = 4.771 > F crit = 4.066 at α = 0.05. Further analysis using the LSD test revealed two groups with significantly different inhibitory effects: the 75% and 50% concentration groups showed significantly higher inhibitory activity compared to the 25% and 12.5% groups.
