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.&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;
