Phytochemical Properties And Antimicrobial Activities From Morinda Citrifolia Linn Fruit Extract

Abstract

The main purpose of this study is to determine phytochemical properties and antimicrobial activity of Morinda Citrifolia Linn (Noni) fruits and leaves. In this study, the Morinda Citrifolia Linn fruit extract was initially carried out by only one solvent ethanol due to the fact that it is harmful to our health in the extraction of methanol or even with hexane. Although methanol is the solvent which helps to take the highest yield of the extraction, ethanol is a popular solvent which can be used in the extraction of Morinda Citrifolia Linn in the purpose of further application products. Besides that, the presence of Rutin and Scopoletin brings about the potential properties for further uses. An amount of phenolic and flavonoid were determined in extract showed the ability of antioxidant. By using DPPH assay, the IC50 value was 2.198 ± 0.277 (mg/ml) in leaf and 2.275 ± 0.143 (mg/ml) in fruit which were calculated into ascorbic acid equivalent value as 54.56 mg per 100 grams dried fruit powder and 204.15 mg per 100 grams of dried weight of leaf, respectively. Furthermore, the different antimicrobial activities of Morinda Citrifolia Linn between gram positive bacteria (Staphylococcus Aureus and Bacillus subtilis) is better than gram negative bacteria (Escherichia Coli and Salmonella). The studied indicated that Morinda Citrifolia Linn (Noni) fruits as well as leaves have efficacy in antioxidant and antimicrobial agents.
