Nutritional and Phytochemical Analysis of Spinach Leaf Aqueous Extract: A Comprehensive Study on Proximate Composition, Minerals, Vitamins, and Antioxidant Activity

Vegetable Leaf plays an essential role in food and diet conservation. Spinach, in particular, is recognized for its rich content of vitamins, minerals, and phenolic compounds, making it a superior source of these nutrients. Compared to staple foods such as grains, vegetables leafy contain greater amounts of essential minerals like iron and calcium. This study examines the nutritional and phytochemical analysis of spinach leaf aqueous extract as a comprehensive study on proximate composition, minerals, vitamins, and antioxidant activity of spinach leaf Aqueous extract. The tannins, flavonoids, phenol, glycosides, saponins, and alkaloids are present after the phytochemical screening results.  The moisture, ash, Crude fat, crude fiber, crude protein, carbohydrate, and total Energy content was obtained as follows; ۸.۶۶%, ۱۴.۲۹%, ۲.۴۳%, ۸.۴۶%, ۲۲.۷۵%, ۴۳.۴۰%, and ۲۸۶.۴۷%, respectively, as the results of the proximate analysis. The composition of minerals showed results on the average, potassium concentration recorded was the highest (۴۲۴۹.۳۵ mg/۱۰۰ g), while Zinc was observed to be the lowest with a concentration range of ۵۴.۸۲ mg/۱۰۰ g. The antioxidant activities revealed the highest percent inhibition (۸۶.۱۲%) in ۰.۵um concentration and the lowest percent inhibition ۴۴.۰۹% in ۰.۰۳۱۲۵ um concentration also; vitamins analysis results reveal the highest quantity (۱۹۸.۴۴ mg/۱۰۰ g) in Vitamins A and then the lowest (۰.۷۴ mg/۱۰۰g) in Vit. B۳.  This study shows that vegetables in particular spinach might be a worthy supplement for some diets and elements analyzed.
