Abstract

The inquiry about on in silico screening of chemical compounds of Histamine H2 of Liquorice (Glycyrrhiza glabra L.), aimed to get the potential bioactive compounds found in plants The Liquorice (Glycyrrhiza glabra L.) as a potential inhibitor Histamine H2 with a screening in silico by Autodock Vina Docking process is carried out on enzyme Histamine H2 as receptors and 105 chemical compounds in plants Liquorice (Glycyrrhiza glabra L.) as ligands using Autodock Vina program. ∆Gbind value and lowest RMSD of each compound that has been in the docking taken the value of the free energy change (∆G) as a result of docking. Docking results showed that of the 105 chemical compounds of plant Liquorice (Glycyrrhiza glabra L.)  are all potential as inhibitors Histamine H2  with free energy change (∆G) most low at Glabrene amounted to -9.6 kcal/mol, and the highest Isotachioside amounted to -4.5 kcal/mol.

Abstract

Sappan (Caesalpinia sappan L.) is applied as food and traditional medicine. Chinese teak (Senna alexandrina) is a plant from the tropics that can be developed as an antioxidant. This study was conducted to determine the antioxidant activity of the combination of Sappan and Chinese Teak by the DPPH (1,1 Diphenyl 2 Picrylhydrazyl) Free Radical Scavenging method. The extraction method used was maceration with Ethanol 96% as solvent. Determination of antioxidant levels was done quantitatively using the UV-Vis Spectrophotometer instrument at a wavelength of 514 nm. From the results of the study, the regression value obtained for the comparison of Quercetin is y = 3.1303x + 0.2292 with R2 = 0.9974 and IC50 value of 15.899 μg/mL. For the antioxidant activity of Sappan, the regression value y=0.5769x + 18.543 with R2=0.9969 and IC50 value of 54.53 μg/mL, Chinese Teak obtained regression value y=0.1421x + 17.506 with R2=0.9989 and IC50 value of 228.67 μg/mL, and for the combination obtained regression value y=0.4304x + 36.622 with R2=0.9954 and IC50 value of 40.38 μg/mL. The results of this study indicate that the combination of Sappan and Chinese Teak extracts has a very strong antioxidant effect (<50 μg/mL).
