Abstract

Lignin extract from nipah fruit skin and nipah frond (Nypa fruticans Wurmb) was effectively extracted and used as a corrosion inhibitor on mild steel samples. The corrosion inhibition efficiency of lignin extract in 1 N HCl solution was determined by the weight loss method and surface morphology analysis using an optical microscope. The measurement results showed that the highest efficiency was obtained at the concentration of lignin extract from fruit skin (ELBN) and nipah frond (ELPN) of 82.16 and 78.36%. The adsorption of lignin extract on the surface of mild steel follows the Langmuir isotherm adsorption and includes mixed adsorption leading to chemical adsorption.

Abstract

Maggots or larvae of the Black Soldier Fly (BSF) are decomposer insects widely cultivated in Indonesia due to their efficient and environmentally friendly ability to degrade organic waste. One of the key components in BSF is chitin, which accounts for approximately 17.93% (w/w) of its total body weight. Chitin can be converted into chitosan through deacetylation and hydrolyzed into glucosamine. Glucosamine has been shown to possess potential in the prevention and management of metabolic syndrome-related diseases such as hypercholesterolemia, diabetes, and obesity. This study explores the potential of glucosamine derived from BSF chitin in reducing the risk of metabolic syndrome. The method used is a literature review of various scientific articles. The findings indicate that glucosamine can activate the AMP-activated protein kinase (AMPK) pathway, which regulates glucose and lipid metabolism. AMPK activation inhibits adipogenesis, fatty acid synthesis, cholesterol production, and adipose tissue formation, positively affecting metabolic syndrome management. Therefore, glucosamine derived from BSF chitin has the potential to serve as a natural bioactive agent for the prevention of metabolic syndrome through AMPK pathway regulation.

Abstract

Molecular docking studies of stigmasterol (test ligand) and estradiol (control ligand) against the ER-α receptor were performed using PyRx software. This study aims to determine the interaction between stigmasterol ligands and ER-α receptors by the molecular docking method using PyRx. The study results show that stigmasterol and estradiol have the same binding energy value of -7.3 kcal/mol. The stigmasterol compound could therefore be used as a candidate for breast cancer drugs.

Abstract

Black sea cucumber Holothuria atra is a marine organism from the family Holothuriidae, a source for developing raw pharmaceutical materials, and is abundant in the waters of Lemukutan Island. This study aims to identify steroid compounds from the n-hexane fraction of the black sea cucumber (H. atra) from Lemukutan waters using FTIR and ¹H-NMR instruments. The steps involved in this study include extraction (maceration and partition), phytochemical tests, fractionation (column chromatography), purification, and molecular structure identification. Phytochemical analysis of the n-hexane fraction of H. atra sea cucumber revealed the presence of secondary metabolites belonging to the groups of steroids, alkaloids, phenolics, terpenoids, and saponins. The result of the isolation was a relatively pure isolate with a weight of 0.0303 grams, yellowish white in color, and suspected to be a steroid compound. The results of the n-hexane fraction identification using FTIR showed the presence of several functional groups found in steroid compounds, such as aliphatic C-H bonds, olefinic =C-H bonds, C-O group, C=O group, C=C bond, and OH (hydroxyl) group. The results of the isolate identification using the ¹H-NMR instrument (500 MHz, CDCl₃) showed chemical shift similarities to the β-sitosterol compound from two different references.

Abstract

Litsea firma (Blume) Hook. f., known locally as Medang Piawas, is a Lauraceae plant found in West Kalimantan, which was traditionally used as medicine and reported to contain alkaloids. This study determined the total alkaloid content in ethanol extracts of the roots, stems, and leaves. Phytochemical tests with Dragendorff, Mayer, and Wagner reagents confirmed alkaloid presence, with the highest intensity in stems, followed by leaves and roots. Quantitative analysis by UV-Vis spectrophotometry using caffeine and quinine standards showed the stem extract contained the highest alkaloid levels (18.289 mg CE/g and 2.299 mg QE/g). Cytotoxic activity was evaluated against cancer cell lines (4T1, MCF-7, T47D, WiDr, HeLa, Hep G2) and normal Vero cells using the MTT assay. The root extract exhibited weak cytotoxicity against WiDr cells (IC50 201"“500 µg/mL) but was inactive against other cancer and normal cells. Stem and leaf extracts showed no cytotoxic effects (IC50 >500 µg/mL). These findings indicate that L. firma contains notable alkaloids, predominantly in stems, although its ethanol extracts demonstrate limited cytotoxic activity.
