“…In the previous studies, fruits of P. emblica were known as a rich source of vitamin C and also contained a mixture of flavonoids and phenolic compounds. Moreover, it is an authoritative source of natural antioxidants, which have a free radical scavenging activity [16,17]. Therefore, it is important to note that the total flavonoid and phenolic content of P. emblica in this study positively correlated with their antioxidant properties, confirming their excellent natural antioxidant properties.…”

Introduction: Triphala, a herbal medicine which is a product from Chae Son, Lampang, Thailand, is an unequal-proportional mixture of fruits of three herbs, Phyllanthus emblica, Terminalia chebula, and Terminalia bellirica (2:1:1). Materials and Methods: The contemporary study concentrated on extracts detection and comparative analysis between various annual year (A.D.2017/2018) activities in hexane, ethyl acetate, and methanolic extracts of Triphala. The determination of antioxidant was using by 1,1-diphenyl-2-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP). The broth dilution and agar well diffusion assay were determined antibacterial. Results: Results exposed the valuable biological activity extracts from ethyl acetate and methanol solvents of T. chebula and T. bellirica, which strength is accountable for biological activities. Extracts displayed acceptable radical-scavenging activity analogous with ascorbic acid. The methanol extract of T. bellirica (0.0013 mg/mL), ethyl acetate extract of P. emblica (0.0009 mg/mL), in A.D. 2017 and the ethyl acetate extract of P. emblica (0.0090 mg/mL), the methanol extract of Triphala (0.0176 mg/mL) in 2018, were exhibited higher antioxidant activity. Also, extracts indicated hopeful antibacterial potential against tested strain comparable to chloramphenicol. Conclusion: The results in A.D. 2017 showed that inhibition zone of P. emblica in ethyl acetate extract; S. aureas (8.67 mm), E. aerogenes (8.67 mm), E. coli (EPEC) (7.67 mm), P. mirabilis (7.73 mm) , S. typhimurium (8.33 mm), S. flexneri (8.33 mm) and V. cholera (7.33 mm) together with P. emblica methanol extract; S. aureas (6.67 mm), E. aerogenes (7.76 mm.) and V. cholera (4.0 mm). Therefore, it could be concluded that Triphala may be a talented candidate in pharmaceutical and future medicine.

“…Begitu pula dengan pengaruh metode pengeringan terhadap aktivitas penghambatan radikal DPPH, yang aktivitasnya lebih tinggi dengan menggunakan metode pengovenan dibandingkan metode lainnya. Total flavonoid, fenolik, dan tanin memiliki korelasi yang positif dengan aktivitas penghambatan radikal DPPH (Fitriansyah et al, 2018). Sembiring et al (2018) juga melaporkan bahwa senyawa tanin yang terdapat dalam daun dapat berperan sebagai antioksidan dengan mendonorkan hidrogennya.…”

Daun alpukat mengandung komponen bioaktif yang tinggi sehingga dapat dimanfaatkan sebagai sumber antioksidan alami. Tujuan dari penelitian ini adalah mendapatkan metode pengeringan yang tepat sehingga menghasilkan ekstrak daun alpukat dengan aktivitas antioksidan yang tinggi. Daun alpukat baik yang muda maupun yang tua dikeringkan dengan tiga metode pengeringan yaitu dijemur dibawah sinar matahari, dikeringanginkan dalam ruangan, dan dikeringkan dengan oven. Kualitas daun kering kemudian dianalisis aktivitas antioksidan, kadar air, total fenol, total flavonoid, dan total tanin. Hasil penelitian menunjukkan bahwa daun tua yang dikeringkan dengan menggunakan oven pada suhu 40˚C selama 24 jam menghasilkan aktivitas penghambatan radikal bebas tertinggi yaitu 19,83% dengan kadar air 7,54%, total fenol 6,42 mg/100 g ekstrak, total flavonoid 12,07 mg/100 g ekstrak, dan total tanin 2,48 mg/100 g ekstrak. Kesimpulannya, metode pengeringan dapat memberikan dampak terhadap kadar senyawa bioaktif ekstrak daun alpukat dan aktivitas antioksidannya.Effect of Drying Methods on the Antioxidant Activity of Avocado LeavesAbstractAvocado leaves contain high bioactive components that may be used as a source of natural antioxidants. The purpose of this study was to obtain proper drying method to produce avocado leaf extract with high antioxidant activity. Avocado leaves, both young and old, were dried with three drying methods, which were dried in the sun, room, and oven. Quality of leaves was then measured for antioxidant activity, moisture, total phenol, total flavonoid, total tannins. The results showed that old leaves dried using an oven at 40˚C for 24 hours resulted in the highest radical scavenging activity of 19.83% with 7.54% moisture content, 6.42 mg/100 g extract of total phenol, 12.07 mg/100 g extract of total flavonoid, and 2.48 mg/100 g extract of total tannins. In conclusion, the drying methods might produced specific antioxidant activities.
