Screening of less known two food plants for comparison of nutrient contents: Iranian and indian vegetables

Abstract

Background: Greater consumption of fruits and vegetables is associated with reduced risk of cardiovascular disease, stroke, and cancers. The most important nutrients present in plants are carbohydrates, such as the starch and free sugars, oils, proteins, minerals, ascorbic acid, and the antioxidant phenols. Plants are an essential component of the universe. Human beings have used those as medicine from the very beginning of time. Methods: The proximate composition and mineral constituents of Asparagus officinalis stem and Momordica dioica fruit were evaluated in order to scientific standard methods of Association for Official and Analytical Chemists (AOAC). Results: The stem contained ashes: 10.70% crude protein: 32.69%, crude lipid: 3.44%, crude fiber: 18.50%, and carbohydrates: 34.67%. Stem also have high energy value (384.27kcal/100g) dry weight. Mineral ranges (mg/100g dry weight, DW) were: K (10.94), Na (1.84), Ca (0.67), Fe (0.19), and Zn (2.60). The fruits contained ashes: 9.1%, crude protein: 5.44%, crude lipid: 3.25%, crude fiber: 22.9%, and carbohydrates: 59.31%. The fruits also have high energy value (288.25kcal/100g) dry weight. Mineral ranges (mg/100g dry weight, DW) were: K (4.63), Na (1.62), Ca (7.37), Fe (5.04), and Zn (3.83). Conclusion: Comparing proximate and minerals contents of the stem and the fruit, the results indicated that Asparagus officinalis stem could be a good supplement for some nutrients such as protein, lipid, potassium and zinc, fibre and carbohydrates while Momordica dioica fruit was good source of lipid, crude fiber, carbohydrates, iron and zinc.
