Vanilla (Vanilla planifolia) is prized for its unique flavor, typically consumed as vanilla extract, which requires substantial extraction time using volatile ethanol. Natural deep eutectic solvents (NADES), abundant and non-volatile, have shown solvating ability for bioactive compounds. This study examines the yield of phenolics from vanilla beans based on total phenolic content (TPC), usin…
Since coronavirus disease 19 (COVID-19) was first found in China on 12 December 2019, finding potential treatments for this virus have always been pushed by many countries. The polyphenolic compound contained in Foeniculum vulgare seeds extract has been found to have antioxidant activity and is linked to the protection of diseases. Thus, the aim of this project is to perform extraction of Foeni…
“Kamlowelen” and “Kayu Bawang” are native papuan trees that have never been investigated before. Both tree barks are commonly used as a seasoning, tea, and medicine. In the present study, total phenolic content (TPC), DPPH assay, and phytochemical screening of tree barks extracted using five different solvents (Methanol, acetone, ethyl acetate, chloroform, and hexane) were analyzed.…
