Uji Aktivitas Antioksidan Kombinasi Infusa Daun Sirih (Piper betle L), Ekstrak Etanolik Tanaman Bundung (Actinuscirpus grossus) dan Kulit Jeruk Nipis (Citrus aurantifolia)

Abstract

Piper betle L., the leaf, is the most often used for treatment and has been scientifically proven to have antibacterial activity. Actinuscirpus grossus plants are commonly found in Kalimantan and have antimicrobial properties. Citrus aurantifolia peel has antioxidant effects and nutritious chemical compounds in medicine. The purpose of this study was to determine the effect of antioxidant activity in a combination of Piper betle L., leaf infusion, ethanolic extract of Actinuscirpus grossus plant, and Citrus aurantifolia peel. The research method was experimental by making Piper betle L. leaves infused with water solvent. Simplisia powder of Actinuscirpus grossus plants and Citrus aurantifolia peel extracted by maceration with 95% ethanol solvent. The combination of the three plants was then tested for antioxidants by the DPPH method. Quercetin is used as a positive control. The results showed that the combination of the three plants had moderate antioxidant activity (IC50 128 ppm), but the antioxidant activity was smaller than quercetin (IC50 16.88 ppm). The combination of Piper betle L., leaf infusion, ethanolic extract of Actinuscirpus grossus plant, and Citrus aurantifolia peel has a moderate antioxidant category.

Potential Antioxidant Activity of Kedondong Leaves (Spondias dulcis Forst.) Using DPPH Method (1,1-Diphenyl-2- Pikril Hydrazil)

“…This quantitative test was carried out to determine the absorbance of DPPH after adding the extract. The mechanism for capturing DPPH radicals by antioxidant compounds is through the donation of hydrogen atoms, causing a change in the colour of DPPH from purple to yellow (Nastiti et al, 2021). In this study, DPPH was used at a concentration of 40 ppm.…”

Compound Characterization and Evaluation of Antioxidant Potential of Ethanol Extract Spatholobus littoralis Hassk in Kolaka, Southeast Sulawesi, Indonesia

“…Quercetin was used as a control solution because it is a flavonol from the group of polyphenolic flavonoid compounds found in almost every type of plant and quercetin is a natural antioxidant that has very strong antioxidant activity. This is under research by Nastati [41], quercetin is known to have very strong antioxidant activity because it has a phenolic group (PhOH) as a functional group which is responsible for antioxidant activity because it is capable of being a hydrogen or electron donor. Quercetin was chosen as a positive control solution because quercetin is a natural antioxidant that has very strong activity so it is very suitable as a comparison to determine the antioxidant activity of bajakah tampala extract (Spatholobus littoralis Hassk) [42].…”

Etnofarmakologi: Pengetahuan Khusus Yang Umum

“…Sebelumnya banyak penelitian dari berbagai daerah yang berawal dari bukti empiris untuk dibuktikan secara ilmiah. Salah satunya adalah penggunaan Rimpang Temu Mangga sebagai anti dislipidemia (Nugraha, Henjani, dan Magfirah 2021;Nugraha, Noval, dan Nastiti 2022), Bajakah sebagai anti inflamasi (Nastiti dan Nugraha 2022), Bundung sebagai anti mikroba (Noval, Melviani, et al 2020), dan kombinasi tanaman seperti Jeruk Nipis, Bundung, serta Sirih yang memiliki potensi sebagai anti penuaan dini (Nastiti, Noval, dan Kurniawati 2021).…”
