The result for the physical characterization of different Dioscorea species in tuber extracts has a boiling point of 97.6°C, milky white in color, unpleasant in odor, has a density of 0.81 g mL, and has a pH of 4.9. In solubility, the ethanol and water are miscible. While the tuber extracts has a boiling point of 98.6°C, brown in color, like tea in odor, has a density of 0.86 g mL, and has a pH of 5.6, in solubility the ethanol and water are miscible. UV Vis analysis was used to determine the vitamin A and vitamin E content of Dioscorea species and was compared to standard sample. The vitamin content analysis shows that the sample has good natural vitamins. Jonalyn E. Espuelas | Karina Milagros R. Cui-Lim | Merle N. Tonog | Rolando A.
