African leaves (Vernonia amygdalina Del) is a plant that can be used as a medicinal plant because it contains flavonoid compounds that are effective as natural antioxidants that can suppress free radicals. The purpose of this study was to determine the antioxidant activity of the purified extract of Vernonia amygdalina Del. Antioxidant activity test of purified extract of Vernonia amygdalina Del leaves against 1,1-diphenyl-2-picrylhydrazil (DPPH) was measured with a UV-Vis spectrophotometer at a wavelength of 516nm using Vitamin C as a comparison. The results of the non-specific parameters of Vernonia amygdalina Del leaf Simplicia were drying shrinkage of 0.79±0.02%; water content of 7.33±2.08%; water-soluble essence content of 20.5±1.73 %; and ethanol of 14.5±4.35 %. The results of purified extract screening of Vernonia amygdalina Del leaves, contained chemical compounds, namely the class of flavonoid compounds, tannin compounds, steroid compounds, and saponin compounds. Testing for flavonoids using the Thin Layer Chromatography method on the purified extract contained two spots with Rf values of 0.68 and 0.5 while in quercetin there was one spot with an Rf value of 0.68, thus the purified extract of Vernonia amygdalina Del leaves contained flavonoids. Vernonia amygdalina Del leaf purified extract has a very strong antioxidant activity with an IC50 value of 13.54±0.10 µg/mL. The results showed that the purified extract of Vernonia amygdalina Del leaves had very strong antioxidant activity.

“…The results of the organoleptic examination can be seen in Table 3. Examination of water and ethanol-soluble essences was carried out to provide an initial description of the number of compounds that can be extracted with water and ethanol solvents (Ladeska & Dingga, 2019). The results of testing the water-soluble essence and ethanol extract of ethanol and NADES can be seen in Table 4.…”

Ethanol extract from the leaves of Morus alba, an herb, has been widely used for medicine, including commercial formulations. This study aims to compare the characteristics of NADES extract using the MAE method and the maceration method. Mulberry leaf simplicia (Morus alba. L) ethanol extract was made with various ethanol concentrations of 50%, 60%, 70%, 80%, and 90%, and NADES (Natural Deep Eutectic Solvents) extract with a solvent ratio of 1:20 and 1: 30 on the MAE (Microwave Assisted Extraction) method with a time of 5 and 10 minutes. Measurement of total flavonoid content and total phenolic content was carried out by UV-vis spectrophotometry with quercetin and gallic acid as reference standards. The results showed that the ethanol extract with ethanol concentrations of 50%, 60%, 70%, 80%, and 90% had an average total flavonoid content; and total phenolic: 0.73%, 0.9%, 1.32%, 1.18%, 0.77%; total phenolic 96.789 mg/g, 71.262 mg/g, 126.465 mg/g, 116.643 mg/g, 93.366 mg/g. NADES extract with a solvent ratio of 1:20 at MAE 5" and 10" minutes obtained flavonoid levels of 0.36%, 0.4%, and total phenolic levels of 36.099 mg/g; 75.621 mg/g. While a ratio of 1:30 with an MAE time of 5" and 10" minutes, the flavonoid content was 0.44%; 0.48%, and the total phenolic content of 61.884 mg/g; 121.237 mg/g. Results of water-soluble essence of ethanol extract; NADES is 26%–31%; 21–24%. Result of ethanol soluble extract content of ethanol extract; NADES is in the range of 36%–42%; 85%–86%. Result of the specific gravity of ethanol extract; NADES is in the range of 0.82 g/mL–0.95 g/mL; 1.08 g/mL–1.18 g/mL. The ethanol extract pH test results were; NADES in the range 6.90–7.01; 7.59–7.89.

ABSTRAKPemanfaatan tumbuhan yang berkhasiat obat dari alam yang berlebihan akan menyebabkan terjadinya penurunan populasi tumbuhan obat. Tujuan kegiatan ini untuk membudidayakan tanaman yang berpotensi berkasiat obat. Metode yang digunakan dalam penelitian ini adalah wawancara, observasi, FGD (Focus Group Discussion), dan pelatihan budidaya yang dibagi dalam beberapa tahap, yaitu tahap persiapan, sosialisasi, dan budidaya tanaman. Hasil kegiatan menunjukan ini bahwa jumlah tanaman obat yang dibudidaya berjumlah 20 jenis dengan kondisi terawat dan tumbuh dengan baik. Tanaman obat yang dibudidayakan memiliki banyak manfaat sebagai obat.
