Abstract
Abstract Pandanus amaryllifolius Roxb. was commonly used in Vietnam as a fragrance because of its aroma. These aromatic plants are the primary source of medicinal herbs because of their valuable biological activities. This study was aimed at determining the phytochemical content, Total flavonoids contents (TFC), total phenolic content (TPC) and antioxidants were analyzed by Folin-Ciocalteu and DPPH scavenging assays, respectively. The total flavonoid content is measured by the aluminum chloride method. The qualitative phytochemical analysis confirmed the presence of flavonoids, terpenoids, coumarin, and reducing sugar, which is chemical components in Pandanus amaryllifolius Roxb extract. Results showed that ethanol extract exhibited higher DPPH (129.327 ug/ml) and TPC (38.12 mgGAE/DW) activity than water extraction (265.738 ug/ml and 10.97 mgGAE/DW). Research shows that using this plant more in pharmaceuticals or food should be focused and developed.
