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;

&lt;p&gt;&lt;strong&gt;Background&lt;/strong&gt;: NADES is an alternative solvent in the extraction of metabolites from plants which has many environmental benefits, such as low toxicity, biodegradability, can dissolve polar and non-polar compounds, low costs and simple preparation. &lt;strong&gt;Objective&lt;/strong&gt;: This study aims to determine the effect of natural deep eutectic solvent-based ultrasonic-assisted extraction (NADES-UAE) on enrichment of caffeine and chlorogenic acid in extract from green coffee beans (&lt;em&gt;Coffea canephora&lt;/em&gt;).&lt;strong&gt; Methods:&lt;/strong&gt; The powders were extracted using NADES-UAE method in several types of extraction condition, including the composition of NADES, water addition in NADES and extraction time. Caffeine and chlorogenic acid content were analyzed using HPLC, reverse phase system and C18 ODS-3 column. &lt;strong&gt;Results&lt;/strong&gt;: The highest of caffeine and chlorogenic acid content was respectively, 7.89 mg/g and 28.62 mg/g (composition of NADES betaine: sorbitol [1:1.2] ratio and NADES-water addition [1:2] ratio for 30 min). &lt;strong&gt;Conclusion&lt;/strong&gt;: This research showed that the composition of NADES, extraction time and water addition are important parameter in extracting caffeine and chlorogenic acid content in green coffee beans.&lt;/p&gt;
