Abstract

Meniran (Phyllanthus niruri L.) is a wild plant in the Euphorbiaceae family which grows in tropical climates. The plant is known to possess antioxidant activity and is rich in phenolic compounds. Since plants with high phenolic content and high antioxidant activity are known to exhibit high tyrosinase inhibitory activity, the purpose of this study is to determine the inhibitory activity of the tyrosinase enzyme by the methanol extract of meniran (P. niruri L.) and to isolate secondary metabolites from the extract and fractions which exhibit inhibitory activity against tyrosinase. The in vitro tyrosinase inhibitory activity assay was conducted using the 96-well microplate method with kojic acid as the positive control, while the separation and purification of compounds were carried out using chromatography techniques. The methanol extract and n-hexane fraction showed tyrosinase inhibitory activity with IC50 of 11.05±0.16 and 2.57±0.08 mg/ml, respectively. Three bioactive compounds were succesfully isolated from the n-hexane fraction. Based on the UV and NMR spectra, compounds 1, 2, and 3 were identified as phyllanthin, phyltetralin, and hypophyllanthin, respectively. Furthermore, phyllanthin (1) was shown to demonstrate inhibitory activity against tyrosinase with IC50 of 0.6322 mM. In conclusion, both meniran extract and phyllanthin (1) were found to exhibit inhibitory acitivity against the tyrosinase enzyme. In the future they can be candidates for the treatment against hyperpigmentation and also as an active ingredient in skincare formulations.

In this research, in silico interaction study was performed between 31 compounds reported to be found in E. americana with the selected target proteins for antifungal and antitoxoplasmosis activity using the molecular docking method. An ORPs (OSBP-related proteins), Osh4 (PDB ID: 1ZHX), and N-myristoyltransferase (Nmt, PDB ID: 1IYL) were used as the antifungal target proteins. Toxoplasma gondii purine nucleoside phosphorylase (TgPNP, PDB ID: 3MB8) and calcium-dependent protein kinase-1 (TgCDPK1, PDB ID: 4M84) were used as antitoxoplasmosis target proteins. Three-dimensional structures of the test compounds were made and optimized using GaussView 6.0 and Gaussian 09W. The target proteins were prepared using the Discovery Studio 2016 Program. Aquatic toxicity prediction as the preliminary assessment of the safety of the compounds was performed using ECOSAR v2.0. The results suggest that the compound having both the smallest free binding energy compared with positive control and other test compounds and low predicted toxicity is β-sitosterol with a free binding energy of ‒11.55 and ‒11.18 kcal/mol towards Osh4 and Nmt and ‒8.06 and ‒10.29 kcal/mol towards TgPNP and TgCDPK1, respectively.

Abstract

Eleutherine americana (E. americana) is a medicinal plant commonly found on the island of Borneo, Indonesia. This plant is known to have several biological activities. However, anthraquinone residues are generally present as contaminants. This study was aimed to develop a method of determining the levels of 9,10-anthraquinone in plant extracts and fractions using High Performance Liquid Chromatography (HPLC). The research aims to optimize the mobile phase, the system suitability test, and the system validation. The optimal mobile phase was acetonitrile:distilled water 1:1 v/v with a flow rate of 1.25 mL/min. The validation result shows that the linearity was obtained with a correlation coefficient (r) of 0.9995 and an r2 coefficient of 0.9991. The estimated limits for detection and quantification values were 0.178 and 0.594 µg/mL, respectively. In the intraday and inter-day accuracy test, the coefficient of variance for reference was 0.627 and 0.774, while the results for the sample were 2.966 and 2.658. The percentage recovery rate for reference was between 98.976–101.452%, and for the sample, the result was 89.191–94.667%.

Abstract

Asthma-plant contains high amount of quercitrin which make it a potential new source for flavonoids. This study aims to develop a method of quercitrin enrichment by utilizing macroporous resin, which is known to be safer, more eco-friendly, economics, and efficient. Evaluations were conducted over the performance and separation characteristics of the macroporous resin in quercitrin enrichment as well as the adsorption and desorption of quercitrin by the macroporous resin. The results showed that the adsorption process of the macroporous resin in relation to the amount of quercitrin in the extract were in accordance with the second order model, which means that the process of adsorption is affected by other compounds. Furthermore, the examination of the isotherm adsorption fit the Freundlich’s model (R2 = 0.9850) rather than the Langmuir’s one (R2 = 0.4334). In the optimal condition, the enrichment of quercitrin by using macroporous resin increased the abundance of quercitrin by nearly five times, from 3.60% of quercitrin content in the extract to 17.02% in the quercitrin-rich fraction, with recovery yield of 50.39%.
