Abstract

Vegetable oil extract moringa leaf (Moringa Oleifera Lamk.) is an herbal oil that has the potential as a medicine. The study aimed to determine the content of secondary metabolites through photochemical tests and the total phenol content of Moringa leaf extract in extra virgin olive oil and virgin coconut oil. The extraction method used is hot maceration with various doses of Moringa leaves. The best amount is used by extraction with variations in temperature and heating time. The functional groups of herbal oils were identified using an FTIR spectrophotometer. Phytochemical test results showed that the vegetable oil extract of Moringa leaf contains secondary metabolites in the form of flavonoids, phenolics, terpenoids, alkaloids, steroids, and tannins. The highest total phenol content in Moringa leaf extract in virgin olive oil at a concentration of 40%, extraction temperature 50°C with a heating time of 2 hours with a total phenol content value of 15.78% GAE (Gallic Acid Equivalent). The results of the FTIR interpretation show that herbal oils have O-H, C-H, C=O, C=C aromatic, C-O, and aliphatic C-H functional groups.

Abstract

Biosorption of Cu (II) using bacteria Pseudomonas aeruginosa FNCC-0063 was immobilized on calcium alginate (PAI). This research examined the effect of various parameters such as pH, contact time, and initial Cu (II) concentration. The biosorption mechanism of Cu (II) was studied by sequential desorption with H2O, KNO3 1 M, HNO3 0.5 M and Na2EDTA 0.1 M. Cu (II) concentration was analyzed using atomic absorption spectrophotometer (AAS). The results showed that optimum Cu (II) ion biosorption occurred at a pH biosorption rate constant of 0.03724 g mg-1.min-1. The kinetics studies showed that Cu (II) biosorption follows pseudo-second-order. The biosorption capacities of 36.60 mg/g. Cu (II) Biosorption followed the Freundlich equation, as shown by a high correlation coefficient (R2) of about 0.99. Ionic bonds dominated the biosorption mechanism of Cu (II) ion on immobilized PAI.

Abstract

Dental caries is caused by the Streptococcus mutans bacteria, which causes a food deposit to harden and adhere to the tooth surface. Cavities will develop if food residue is not removed. Herbal plants, specifically sappan wood, can be used as an antibiotic. The purpose of this study was to look at the secondary metabolite content of sappan wood extract, antibacterial activity, and the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of sappan wood extract against Streptococcus mutans bacteria. This research method includes the maceration of sappan wood extract with 96% ethanol solvent, phytochemical screening of sappan wood extract, inhibition zone test with paper disc method, and MIC and MBC tests. Qualitative testing revealed that the sappan wood extract contained alkaloids, flavonoids, tannins, and saponins. Flavonoids, tannins, and saponins are all constituents of plants. Secang wood extract has antibacterial activity against Streptococcus mutans, as evidenced by the formation of inhibition zones at concentrations of 20%, 40%, 60%, 80%, and 100%, namely 8.75±0.354; 11±1.41;, 12.75±0.354; 16.25±0.354; and 17.5±0.000 mm. Sappan wood ethanol extract had a MIC of 12.5% against Streptococcus mutans and an MBC of 25%.

Abstract

The appearance of brown spots and wrinkles can be a sign of aging which can increase the risk of cancer. Compounds in broadleaf mahogany seeds (Swietenia macrophylla) contains many compounds and is known to have anticancer activity. The purpose of this study was to determine the compounds in the seeds of these plants have the potential to antiaging by analyzing their molecular docking interaction on the MMP-1 enzyme (matrix metalloproteinase), NEP (neprilysin), PPO3 (polyphenol oxidase), and as a support for the search for anticancer compounds. Two compounds that have the potential as strong inhibitors towards MMP-1 and PPO3 enzymes, namely β-cytostenone and 3β-hydroxystigmast-5-en-7-on which is a steroid group, as well as germacrena A and germacrena D which are terpenoids. Only compound 3β-hydroxystigmast-5-en-7-on which has the potential as a strong inhibitor of the NEP enzyme. All compounds have the potential to be strong inhibitors according to the Lipinski rule. Only compounds which binds to the PPO3 enzyme which has better activity than natural ligand based on ΔG and Binding Site Similarity (BSS) values.

Abstract

Corrosion of iron is a persistent problem that affects its structural integrity and durability in various industrial applications. The design of effective corrosion inhibitors is crucial for mitigating aluminum corrosion. In recent years, coumarin derivatives have shown promising potential as corrosion inhibitors for iron due to their unique chemical properties. In this research, we employ density functional theory (DFT) calculations to investigate electrochemical parameters of coumarin derivatives on iron corrosion. Coumarin (a) and its derivative: hymechromone (b), esculetin (c), and scopoletin (d) are analyzed using DFT calculation. Some descriptor is used to identify such as ionisation energy (I), electron affinity (A), EHOMO, ELUMO, Egap, electronegativity ( ), hardness ( ), number of fraction electron transferred ( N). Based on the EHOMO, ELUMO, Egap, electronegativity ( ), hardness ( ), the order of inhibitor potential of coumarin and it derivative is c > d > b > a. However, based on the number of fractional electrons transferred ( N), the potential inhibitor of coumarin and it derivative are c > b > d > a.
