摘要：Background and Objective: The marine bean ( Vigna marina ) is one of tropical legumes grown in coastal areas and can be used as renewable food source. The present study aimed to assess the nutritional and antioxidant capacity of marine bean as renewable food source for the coastal communities.Materials and Methods: The leaves and fruits of marine bean were sampled from sandy area, shaded area and on the tree canopy. The samples then labeled and kept in the box contained dry ice and brought to the laboratory. All samples were washed thoroughly in tap and distilled water and then separated for the fresh and drying samples analysis. The protein, fat, carotenoid and micronutrients contents in leaves and seeds of marine beans were determined. Results: The results showed that the protein content in leaves of Vigna marina ( V. marina ) ranges from 1.73±0.37-3.59±0.88 mg g1, while the protein content in its seeds ranges from 4.98±0.16-5.10±1.44 mg g1. However, the fat content in leaves of V. marina ranges from 4.94±0.13-6.22±0.61 mg g1, while it ranges from 6.92±1.32-8.54±1.33 mg g1 in seeds. The carotenoid content ranges from 233.32±27.27-287.35±4.45 mg/100 g) and ranges from 18.14±2-29 25.06±0.91 mg/100 g in seeds of V. marina . Moreover, the ascorbic acid content in leaves of V. marina ranges from 5.56±0.17-6.27±0.25 ppm and it ranges from 5.07±0.02-5.17±0.04 ppm in its seeds. The mean of micronutrients of Na, Fe, Mn, Cu, Zn contents in leaves were estimated as 4.6, 0.32, 0.051, 0.062 and 0.38 mg g1, respectively. In addition, micronutrients of Na, Fe, Mn, Cu, Zn contents in seeds were 6.6, 0.25, 0.044, 0.048 dan 0.27 mg g1, respectively. Conclusion: The leaves and seeds of V. marina contained higher nutrient and antioxidant contents.
