“…The maceration method was used to obtain the extracts due to its simplicity and use of basic equipment, 9 while 70% ethanol was used as the extraction solvent because it can extract more secondary metabolites compared to other organic solvents. 23 The ethanol extract gave a yield of 14.09%. Phytochemical screening is done to reveal the class of secondary metabolites present in plants.…”

Etlingera elatior (Jack) R.M. Smith is an endemic plant of North Luwu, Indonesia. It is used traditionally as acidifiers in food. This study aim to evaluate the antioxidant activity, total phenolic and total flavonoid contents of the ethanol leaf extract of E. elatior. The dried leaves of E. elatior were extracted by maceration in 70% ethanol at room temperature for three days. The antioxidant activity of the extract was assessed using the 2,2-diphenyl-1-picrilhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging assays and ferric reducing antioxidant power (FRAP) method. The total phenolic and total flavonoid contents were determined using the Folin-Ciocalteu and Aluminium chloride colorimetric methods. The results showed that E. elatior leaf extract had antioxidant activity with IC50 value of 42.45 ± 1.37 µg/mL compared to 2.78 ± 0.01 µg/mL for vitamin C (Positive control) for DPPH radical scavenging activity. While for the ABTS scavenging activity, the IC50 was 26.46 ± 0.09 µg/mL compared to 0.15 ± 0.02 µg/mL for vitamin C. In the FRAP assay, the extract showed a ferric reducing antioxidant power of 78.52 ± 0.26 mgAAE/g extract. The total phenolic and total flavonoid contents of the extract were 27.19 ± 0,07 mgGAE/g extract and 4,60 ± 0,01 mgQE/g extract, respectively. From the results of the study, it can be concluded that the ethanol leaf extract of E. elatior has strong antioxidant activity which could be attributed to its high phenolic and flavonoid contents.

“…Kandungan flavonoid pada buah pare mempunyai potensi sebagai tabir surya karena adanya gugus kromofor yang mampu menyerap sinar UV sehingga mengurangi intensitasnya pada kulit (Whenny et al, 2015). Flavonoid berfungsi sebagai penangkap radikal hidroksi dan superoksida dan banyak menghambat reaksi oksidasi (Hasanah & Novian, 2020).…”

Kulit manusia memiliki perlindungan tersendiri terhadap bahaya sinar UV, tetapi radiasi ultraviolet yang berlebih dapat mengakibatkan perlindungan ini berkurang. Radiasi ultraviolet seringkali menyebabkan kerusakan jaringan tubuh seperti eritema, edema, sunburn, tanning, hyperplasia, photoaging bahkan kanker kulit. Tabir surya merupakan salah satu produk yang dapat digunakan untuk membantu melindungi kulit. Tabir surya dari bahan alam berpotensi digunakan sebagai perlindungan kulit dari radiasi ultraviolet. Tujuan penelitian ini untuk mengetahui potensi dari bahan alami yang dapat dimanfaatkan sebagai tabir surya. Metode yang digunakan adalah literatur review pada database jurnal penelitian dari tahun 2018 sampai 2023. Hasil penelitian menunjukkan adanya potensi dari berbagai bahan alam baik dalam bentuk ekstrak maupun sediaan dengan pengujian secara in vitro. Tanaman yang dapat dimanfaatkan sebagai tabir surya seperti daun stroberi, pegagan, buah sirsak, buah pare, daun kelor, ganggang hijau, daun keledang dan biji buah alpukat. Tanaman tersebut banyak ditemukan mengandung senyawa fenolik terutama flavonoid yang terbukti mampu menyerap paparan sinar UV.

“…This analysis aims to determine the total flavonoid content in the extract obtained from the standard curve equation. The choice of quercetin as a standard solution is due to its compounds that are widely distributed in plants (Hasanah & Novian, 2020). The following absorbance data on the concentration of quercetin produces a standard curve line y= 0,0013x + 0,0783 with an value R 2 = 0,945 (Figure 1).…”

Pumpkin fruit (Cucurbita moschata. D) belongs the Cucurbitaceae family which is a functional vegetable widely distributed in Indonesia because it has nutritional value and health benefits. This study aims to determine the value of total flavonoid content and antioxidant activity in the ethanol extract of unripe, mature and ripened pumpkin. Simplicia powder was extracted by maceration method using 96% solvent. Testing the total flavonoid content with the addition of AlCl3 at a wavelength of 425 nm and the antioxidant activity test was carried out using DPPH (1-1-diphenyl-2-picrylhydrazyl) as a free radical with a maximum wavelength of 515 nm using microplate reader. The results of the study concluded that the ethanolic extract of pumpkin flesh had a total flavonoid content of 0,146 mgQE/100g in unripe fruit, 0,221 mgQE/100g in mature pumpkin, 0,191 mgQE/100g in ripened pumpkin. The antioxidant activity of the ethanol extract of unripe, mature, and ripened pumpkin fruit obtained was not active or did not completely reduce free radicals.
