ABSTRACT
Annona muricata is a member of the Annonaceae family and is a fruit tree with a long history of traditional use. Annona muricata , also known as sour sop, graviola and guanabana, is an evergreen plant that is mostly distributed in tropical and subtropical regions of the world. The fruits of Annona muricata are extensively used to prepare syrups, candies, beverages, ice creams and shakes. A wide array of ethnomedicinal activities is contributed to different parts of Annona muricata, and indigenous communities in Africa and South America extensively use this plant in their medicine. In the course of my practical research various analysis was carried out such as proximate analysis, vitamin analysis, analysis of mineral composition and GCMS analysis. The annona muricata (sour sop) leave was grounded into powdered form, weighed 0.2 g of dried sample into the digestion tube. Then I add 10 ml of the mixed acid. Next I bring the digestion tube to the heater and heat. When dense white fume occur I continue to heat until the solution is clear. After that I emove from the heater, cool and add little amount of deionized water. Then filtered the solution with a filter paper whitemann no 42 into a 25 ml volumetric flask. I made the volume up with deionized water to the mark. I prepared a reagent blank without sample same as the sample. I also determined metals of interest with Atomic absorption spectrophotometer. In the determination of the nutritional and non-nutritional component of annona muricata (sour sop), the following analysis was carried out: vitamin analysis, mineral analysis, proximate analysis and GCMS analysis. During the cause of this work more discoveries were obtained regarding the health benefits of annona muricata (sour sop).
