Abstract

The beneficial health effects of spices against common chronic systemic diseases have been well documented. Comparative study of the proximate, mineral and phytochemical components of three spices namely garlic ( Allium sativum L. ), ginger ( Zingiber officinale Rosc.) and pepper ( Capsicum frutescens L.) were investigated. Analysis of the proximate composition revealed that the spices had considerable carbohydrate and crude protein content, but low ash, fibre, moisture and fat except pepper which has high crude fat content. The spices were also characterized by the presence of mineral elements such as calcium, iron, potassium, phosphorus, sodium, magnesium, copper and zinc which are very important to human nutrition. Phytochemical screening indicated that these spices are also rich in phytonutrients including alkaloid, tannin, carotenoids, saponin and flavonoids. The spices had low concentrations of steroids and cardenolides. Overall, the findings indicate that the spices are good sources of nutrients, mineral elements and phytochemicals which could be exploited as great potentials for drugs and/or nutritional supplements. Key words : Comparative, nutritional, supplements, spices.
