Merr. (E.palmifolia) is a medicinal plant containing naphthoquinone, isoliquiritigenin, and oxyresveratrol compound. This study aims to formulate and characterize the &lt;em&gt;E. palmifolia&lt;/em&gt; microspheres delivery system using chitosan variation as the polymer. &lt;strong&gt;Methods: &lt;/strong&gt;The preparation method was the solvent evaporation method. The microspheres delivery system was performed by variation of chitosan concentration in each formulation 0.637% (F1), 1.275% (F2), and 1.912% (F3). The physical and chemical characterizations include Entrapment Efficiency (EE), yield percentage, particle size, particle morphology, FTIR analysis, X-Ray Diffraction (XRD) analysis, and Differential Thermal Analysis (DTA) had been evaluated. &lt;strong&gt;Results&lt;/strong&gt;: The results showed that chitosan concentration variation affected the microsphere's physical and chemical characteristics. Variations in the concentration of chitosan polymer (0.637%, 1.275% and 1.912%) had an effect on the physical characteristics of the microspheres of the resulting Dayak onion bulb extract. The higher the concentration of chitosan used, the higher the entrapment efficiency and the yield yield will increase. Meanwhile, in observing the particle size, the higher the concentration of chitosan used, the smaller the particle size produced. The optimal concentration of chitosan as a polymer at concentration variations of 0.637%, 1.275% and 1.912% to provide good physical characteristics of the Dayak onion bulb extract microspheres was shown in formula 3 with a chitosan concentration of 1.912%. &lt;strong&gt;Conclusion:&lt;/strong&gt; The better characteristic was obtained upon higher chitosan concentration. The best physical characteristics of&lt;em&gt; E.palmifolia &lt;/em&gt;extract microspheres were obtained from chitosan concentration at 1.912% (F3).&lt;/p&gt;

Therefore, the purpose of this study is to synthesize chitosan-tripolyphosphate nanoparticles from mango ginger extract, determine their chemical contents, the nano chitosan characteristics, and its antioxidant activity. &lt;strong&gt;Methods:&lt;/strong&gt; In this study, we macerated mango ginger using 70% ethanol solvent, then performed phytochemical test and formulation of chitosan nanoparticles of mango ginger extract. The group of secondary metabolites that showed positive results with the reagent test was further identified through TLC. &lt;strong&gt;Results:&lt;/strong&gt; The results showed that the extract contained flavonoids and triterpenoids. Also, characterization of chitosan nanoparticles from the extract was conducted with FTIR test, PSA, XRD, and SEM. Based on the results, the nano chitosan particle size was 993 nm and examination with FTIR showed the presence of N-H and P=O groups, indicating ammonium ion interaction from chitosan with the polyanion from TPP and Mango ginger. Additionally, the XRD results showed that the crystals formed were in an amorphous form, which was supported by particle morphology images from SEM. Furthermore, the nanoparticles showed very strong antioxidant activity based on the reaction with DPPH. &lt;strong&gt;Conclusion:&lt;/strong&gt; Based on these results, the phytochemical identification of mango ginger extract showed positive results in flavonoid and triterpenoid compounds. In addition, based on the characterization of the nanoparticles, the mango ginger extract showed positive results, illustrating that the nano chitosan synthesis was successful. Furthermore, the nano chitosan has a very strong antioxidant activity with an IC50 value of 18.08 μg/mL.&lt;/p&gt;
