Abstract

The stability indication of Reversed Phase-High Performance Liquid Chromatography (RP-HPLC) method was validated for quantitative determination of mangiferin on three species mango leaves (Mangifera odorata Griff, Mangifera foetida Lour, and Mangifera indica L.). The samples were extracted by maseration method using methanol and concentrated using rotary evaporator. The method carried out on stationary phase a purospher RP-18 endcapped (25 cm × 4.6 mm i.d., 5 µm) column with a mobile phase consisting of methanol: phosphoric acid 0.1% (v/v) (31:69); flow rate:0.8 mL/min; solvent methanol, detection was carried out at 258 nm. The analytical performace this measurement is good with the value of linearity (r2=0.998), precision (%RSD=0.649%), and accuration (10.67%). The forced degradation studies were carried out according to the International Conference on Harmonization (ICH) guidelines. The results indicating that the complete separation between degradation products and mangiferin peak occured. The degradation limit of mangiferin 5–20% (according to the guideline of ICH) except in basic condition (100%). The method was succesful applied to determine of the mangiferin in pakel (Mangifera foetida), kweni (Mangifera indica) and kopyor (Mangifera odorata) extract. The mangiferin content was obtained are pakel (9.95%), kopyor (7.40%) and kweni (Mangifera odorata) (2.49%) respectively.

Abstract

The many kinds of health benefits of beluntas (Pluchea indica) are already known, but are still limited for vegetables, even though its essential oil is very high. Essential oils, based on research, can be used as an antibacterial and an inhibitor of viruses. Therefore, we conducted counseling and training on the utilization of Beluntas leaf essential oil through isolation to be developed into health products in the Babatan Sidomekar community, Semboro, Jember. The Covid 19 virus pandemic in Indonesia has had an economic impact on small communities. One way to do this is to provide new knowledge and technology by producing products that can be used to increase income and preventive against COVID-19. Presentation products are more modern, have high selling value, and are more durable, which will be easily accepted by the market. The stages of implementing the activity were socialization in the Babatan Sidomekar community, Semboro, Jember, which was carried out well from August to November 2022, and the community was very enthusiastic about receiving counseling and training in making hand sanitizer and antiseptic soap products from the essential oil of beluntas leaf
