The current study mainly aims to apply and optimize the microwave-assisted natural deep eutectic solvent extraction (MANDESE) method of total polyphenol content from Mitragyna speciosa (Korth.) Havil leaves using response surface methodology (RSM) and its extraction mechanism using scanning electron microscopy (SEM) imaging. The extraction process was performed using the maceration and MANDESE method. Total polyphenols content was examined using Folin-Ciocalteu reagent and spectrophotometer UV-Vis. The extraction mechanism was performed using SEM imaging. The extraction condition as experimental design variable factors for optimization using RSM included NADES composition ratio, the liquid-solid ratio, extraction time, and microwave power. The results show that the MANDESE with some different combinations of NADES composition is more effective than a maceration. SEM imaging result shows that the levels of damage of cells and cell walls were more severe after extraction. The optimum extraction condition has obtained the NADES composition ratio of 3 g/g (choline chloride/sorbitol) and the liquid-solid ratio of 20 mL/g for 20 min extraction time with 60\% Watts microwave power. The scale-up confirmation test was obtained the total polyphenols content of 526.12 μg GAE/g sample. This finding demonstrated the optimum condition of the MANDESE method and performed efficiently, rapidly, safely, and environmentally friendly.

Garcinia latissima Miq. belongs to the Clusiaceae family that has been studied with activity as an antibacterial and anti-elastase in vitro. The inhibitory ability of the elastase enzyme from the G. latissima extract. This needs to be tested further by an in silico molecular docking study of the compound. Previous studies have shown that 4-oxo-β-lactam crystals are selective against the human neutrophil elastase (an enzyme protease). It has a structural relationship with its activity to become the basis for inhibiting the elastase enzyme. The purpose of this in silico study was to test whether the isolated compounds from G. latissima (including friedelin, 6-deoxyjacareubin, amentoflavone, and Robusta flavone). The in silico molecular docking method used was Autodock 4.2.6 molecular docking software. This protocol is used to test friedelin, 6-deoxyjacareubin, amentoflavone, and Robusta flavone as ligands for the elastase enzyme receptor. The protocol{\textquoteright}s output was analyzed using the Accelrys Discovery Studio Visualizer 4.0 post-docking analysis method. The results showed that isolated compounds, including amentoflavone, friedelin, and 6-deoxyjacareubin, are active ligands against porcine pancreatic elastase with the free binding energy of -10.94, -7.17, and -6.72 kcal/mol, respectively, and form hydrogen bonds, van der Walls, alkyl, electrostatic, and hydrophobic interaction. In silico physicochemical, lipophilicity, water-soluble, pharmacokinetics, and drug-likeness properties prediction showed characteristics prediction of isolated compound. This study provides an overview of the molecular interactions of isolates compounds from G. latissima against the elastase enzyme.

The present study aimed to evaluate phytochemical and antioxidant activity (in vitro and in vivo) of Origanum vulgare (L.) ethanolic extract. The phytochemical test was assessed using the Clule method in ethanol, ethyl acetate, and hexane. In vitro evaluation of antioxidant activity was determined by radical scavenging assay using DPPH (2,2-diphenyl-1-picrylhydrazyl) as an artificial free radical activity. In vivo test was conducted to evaluate the effect of malondialdehyde (MDA) level in blood plasma during maximum physical activity treatment. In vivo test was done using 25 male Sprague Dawley rats in pre and post-test control group design. The phytochemical test of O. vulgare ethanol extract was showed some compounds, such as a flavonoid, alkaloid, triterpenoid/steroid, essential oil, and tannin, then in ethyl acetate and hexane. In vitro assay showed that O. vulgare extract has strong antioxidant activity with an IC50 value of 133.47 μg/mL. While in the in vivo test, the most effective dosage is 20 mg/200 gr B.W., represented by a significant decrease of MDA level (0.509 nmol/mL) before and after treatment. So, the ethanolic extract of clove has potency as an herbal antioxidant because of the low level of IC50 and can decrease the MDA level.

Applying green chemistry principles in the exploration of an active secondary metabolite from natural products has continued to experience a significant increase in the last decade, mainly natural deep eutectic solvent (NADES) usage. Mitragyna speciosa (Korth.) Havil (Rubiaceae family) is a native of East Kalimantan, which is traditionally used as an herb to treat headaches and inflammation by drinking boiled water a few leaves. On the other hand, this plant has an addictive effect. This study aims to determine the single factor effect of NADES citric acid{\textendash}glucose-based microwave-assisted extraction (MAE) to obtain the yield of total polyphenols content (TPC) from M. speciosa leaves. Dried powder of M. speciosa leaves was extracted using NADES citric acid-glucose based MAE method with some different conditions such as NADES (citric acid-glucose) ratio (4:1, 5:1, 6:1 g/g), solid-liquid ratio (10:1, 15:1, 20:1 mL/g), microwave power (90, 270, 450 Watts), and extraction time (15, 20, 25 min). The determination of TPC was performed using Folin-Ciocalteau reagent and gallic acid as a standard with different concentration levels. The absorbance measured using spectrophotometer UV-VIS at 746 nm to obtain a regression formula of Y = 0.0022X{\textendash}0.00095, where R2 = 0.9977. Based on the result, the best of single factor condition effect was obtained the TPC value including NADES ratio of 248.69 mg GAE/g sample (5:1 g/g citric acid-glucose), a solid-liquid ratio of 146.93 mg GAE/g sample (15:1 mL/g solvent-sample), microwave power of 192.20 mg GAE/g sample (270 Watts), and extraction time of 358.59 mg GAE/g sample (15 min). The single factor effect of NADES citric acid-glucose-based MAE shows a difference in TPC value based on various conditions of this method.

Background: Tyrosinase is an enzyme that plays an essential part in the process of melanin synthesis. High exposure to ultraviolet (UV) radiation or high stimulation of melanocytes could cause excessive melanin pigments to lead to hyperpigmentation. Objective: This study aimed to find potential natural skin lightening ingredients from Garcinia latissima Miq. Methods: Stem bark, fruits, and leaves of Garcinia latissima Miq. were extracted with successive maceration. The tyrosinase inhibitory activity test was measured spectrophotometrically at 490 nm using 3,4-dihydroxy-L-phenylalanine (L-DOPA) as substrate and kojic acid as a positive control. Results: The tyrosinase inhibitory activity test at a concentration of 100 ppm showed that the bark ethyl acetate extract 15.94\% {\textpm} 7.70, bark methanol extract of 28.94\% {\textpm} 5.73, fruit n-hexane extract 25.16\% {\textpm} 10.22, fruit methanol extract 23.26\% {\textpm} 9.10; and leaf methanol extract 30.59\% {\textpm} 0.63 with kojic acid inhibition 65.07\%. Conclusion: Methanol extract of leaf from Garcinia latissima Miq was the most active extract as a tyrosinase inhibitor.
