Abstract

This study aims to examine asiatic acid from Barringtonia asiatica seed extract as an anti-cataract. The presence of asiatic acid in the extract was confirmed using LCMS. The study was conducted using the HKSA method and it is independent of the molecular docking method. Molecular modeling was carried out using the Avogadro program. Descriptors computation using NWChem (DFT method, 6-311G base set), Swiss ADME, Molinspiration, and ADMET. Molecular tethering and visualization using Autodock Tools 1.5.6. and Discovery Studio 2019 Client. The best compounds that fight against cataracts are 9- (methoxymethyl)-1,2,6a, 6b, 9,12a-hexamethyl-10,11-dioxo-1,2,3,4,4a,5,6,6a, 6b,7,8,8a, 9,10,11,12,12a, 12b,13,14b-icosahydropicene-4a carboxylic acid. The equation:Log P = 25.593 + (- 0.136) * PSA + (-1.694) * Surface area + (-0.015) * Volume + (1.368) * molar refraction + (0.129) * LUMO + (- 7.007) * HOMO + (- 0.117) ) * E DFT + (-0.037) * E Hydration + (- 0.262) * PolarizationThis molecule was confirmed to be anti-cataract based on the molecular docking against the 4JGF protein target which produced binding energy and inhibition constants of -8.78 and 0.3368 uM.

Abstract

Abstract: This study aims to examine the extract of red trunk binahong seed as a dye in Dye Sensitized Solar Cell (DSSC). (Anredera cordifolia) characterization was carried out by UV-Visible spectrophotometry and resulted in absorption at a wavelength of 537 nm, purification the extract of red trunk binahong seed was carried out by column chromatography using methanol: ethyl acetate asĀ  solvent with ratio of 3: 2 and 10 fractions color were produced. The identification of compounds and functional groups were analyzed by FTIR which showed the presence of betalain derivatives, namely betanidine, betanine, and neobetanin. Molecular weight analysis was carried out by LC-MS and the molecular weight of betanidine was 386.3171. The voltage and current from the DSSC results were measured usingĀ  multimeter, the efficiency of the extract of red trunk binahong seed was 0.64% and the one that experienced a change in color to orange was 0.55%.Keywords:, betalain, betanidine, betanine, DSSC, red trunk binahong
