Abstract

Objectives: An endemic species of Pandanus found in Ando Island Borongan City was subjected to phytochemical analysis to verify presence of some secondary metabolites products by the plant sample. Methods: Qualitative analysis was used in phytochemical testing and color, odor and miscibility testing, while Quantitative analysis was used in pH, boiling point and density of four (4) different types of extracts namely; Dried Leaves (DLE); Dried Fruit (DFE); Fresh Leaves (FLE); and Fresh Fruit (FFE) in determining the extracts’ physical and chemical properties. Results: Results showed that the color of most plant extracts ranges from brown to dark brownish-green, strong odor, a density range from 0.77 to 0.87 g/cc. All extracts are basic and a boiling point range of 92.7 to 102.7 OC. Moreover, all extracts are soluble to polar solvents, but insoluble to non-polar solvent. Phytochemical screening found out that alkaloid is present only on the fruit extract; saponin, steroid, and terpenoid are found to be positive, while tannin was found negative in all extracts. Flavonoid is present in FFE while glycoside is present only on Dried Fruit Extract (DFE). Improvements: It is hereby suggested that a quantitative analysis be carried out on the present secondary metabolites to determine if there is a new type of naturally-occurring compound present in the fruits or leaves of the Pandanus species and perform phytochemical analysis to other parts of the plant such as roots, bark, trunk, etc.
