Abstract
Guava is well known tropical tree which grows up to the 35 feet tall in height. It is abundantly grown in tropic areas for fruit. It belongs to the Myrtaceae family. Guava tree and its all parts have a old history of medicinal values. In this study micro and macro nutrients of guava skin is evaluated. The nutritional values, aflatoxin analysis, antioxidant activity, anti bacterial anti fungal activity of guava skin was evaluated. The purpose of this study was to find the quality and efficiency of guava skin grown in the Soa Asal. Nutration values were found out by the recommended methods of AOAC. The antioxidant activity was find out by the DPPH and FRAP method. Gel ager method was used for the antibacterial analysis. Results of nutritional values indicated that the moisture content, total ash content, fiber content, protein content, fat content and carbohydrates contents were 5.25%, 7.32%, 17.5%, 3.2%, 0.65% and 20.85% respectively. Phytochemical analysis results showed that the ethanolic extract have maximum phtochemicals. Tannin, Phenol, carbohydrates and sterol were in high content. Aflatoxin analysis showed that no aflatoxin from four types was present in the guava skin. Antioxidant activity analysis showed that the %age inhibition and the reducing capacity were maximum in the yellow ripened skin. This was concentration dependent. Antibacterial activity was highest in the ethanolic extract Salmonella spp. and it was also concentration dependent. Antimicrobial analysis showed that guava skin has a significant quantity of pathogens. Results of the study indicated that guava skin of this area’s guava is safe for use and it can be use for nutritional and medicinal purposes.
