Thus it can be used as a source of medicinal raw materials. &lt;em&gt;Piper betle&lt;/em&gt; 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 &amp;lt;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.&lt;/p&gt;

Havil (&lt;em&gt;Rubiaceae&lt;/em&gt; 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–glucose-based microwave-assisted extraction (MAE) to obtain the yield of total polyphenols content (TPC) from &lt;em&gt;M. speciosa&lt;/em&gt; leaves. Dried powder of &lt;em&gt;M. speciosa&lt;/em&gt; 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–0.00095, where R&lt;sup&gt;2&lt;/sup&gt; = 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.&lt;/p&gt;
