Piper betle var. nigra has potency as an herbal medication. Thus it can be used as a source of medicinal raw materials. Piper betle var. nigra simplicia and extracts must be controlled to obtain unswerving quality and ensure their pharmacological effects by standardizing them through several specific and non-specific parameters. Specific parameters were analyzed organoleptically in the ethanol extract, namely having a thick consistency, brownish-green or blackish-green color, a mild peculiar odor, a bitter, cherish taste, and a slightly spicy flavor. The microscopic simplicia powder profile is as follows: the lower epidermis with idioblasts in oil cells contour and upper epidermis, sclerenchyma, covering hairs, and transport bundles ladder-type thickening, and idioblasts in oil cells contour. Extract content analysis of simplicia and black betle leaves ethanol extract showed water-soluble extract content of 2.77\% and 12.45\% and ethanolsoluble extract content of 1.38\% and 19.1\%. Secondary metabolites in the ethanol extract are flavonoids, polyphenols, tannins, saponins, alkaloids, and steroids. The non-specific parameters of the simplicia and extract are as follows; total ash content of 12.1\% and 7.43\%; acid insoluble ash content of 4.45\% and 1.57\%; drying shrinkage of 14.5\% and 15.85\%; total lead (Pb) contamination 47.5 ppm and 1.2 ppm; and the total cadmium (Cd) contamination \<0.2 ppm. The total bacterial contamination in the extract was 4.3x105 colonies/g. The total yeast contamination was 8.3x105 colonies/g and volumetric mass density of the water-soluble extract of 0.96 g/mL and the volumetric mass density of the ethanol-soluble extract of 1.01 g/mL.

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.
