Abstract

Studies in silico offer an exciting world where researchers use the power of computing to explore a variety of scientific phenomena. In silico allows researchers to virtually test thousands of potential compounds, including natural ingredients, interacting with biological targets. This can speed up drug discovery and reduce reliance on expensive laboratory trials. Erythrina subumbrans is a plant in the Papilonaceae family that has been phytochemically tested to contain flavonoids suspected of having antipyretic effects. The study aims to identify the most potentially antipyretic compounds among the eight flavonoid groups of the branches and roots of Dadap Serep (Erythrina subumbrans). The study uses the molecular docking method. Tests were conducted against eight flavonoids of the branches and roots of the Dadap serep, namely pinocembrin, 3,6,4’-trichydroxyflavone, 3,6-dihydroxylflavon, lupalbigenin, erysubin F, genistein, 5-hydroxyphoronone, and abyssinone V, as well as positive controls of paracetamol against target proteins with PDB code 1CX2. The data analysis compared the total binding energy and hydrogen binding scores on the emerging amino acid residues. The test results showed that the three most potentially antipyretic compounds were lupalbigenin, erysubin F, and abyssinone V, with consecutive total bending energy scores of -126.3 kcal/mol, -113.1 kcal/mol, and -111.8 kcal/mol.

Abstract

Jamu is a traditional Indonesian medicine. Herbal medicine for rheumatism and “pegal linu” is one of the most widely consumed types of traditional medicinal products by the public, so it is a type of traditional medicinal preparation that is prone to the addition of chemical drugs (BKO). All types of traditional medicines are prohibited from containing isolated or synthetic chemicals with medicinal properties. Samples of rheumatism and “pegal linu” jamu were purchased from Grobogan, Central Java, and Gunungkidul, Yogyakarta. Two samples were purchased from Grobogan, while four samples were purchased from Gunungkidul. The standards used were mefenamic acid, phenylbutazone, and diclofenac sodium. Qualitative analysis was carried out using thin-layer chromatography and quantitative analysis using UV-visible spectrophotometry. Validation of the analytical method is carried out by setting four parameters: linearity, precision, limit of detection, and limit of quantitation. Information about the content of BKO in traditional medicines circulating in the Grobogan and Gunungkidul areas, as well as references to valid analytical methods, will greatly assist the government and academics in educating the public about the dangers of long-term consumption of traditional medicine with BKO. The results showed that three of the six samples contained BKO, and the analytical method was valid.
