In Vitro Bactericidal Activities of Extracts From Ripe and Unripe Fruit of 'Noni'

Abstract

In an era of nutraceuticular research, ‘Noni’ fruit is considered as a panacea because of the profound claim on its medicinal uses in treating many diseases inclusive of infections of microbial origin. Hence, the present study was done to know the antibacterial activity of aqueous extracts from ripe and unripe fruits of ‘Noni’ Morinda citrifolia L on gastroenteritic and pyogenic bacteria. The study was done for eight gastroenteritic bacteria and six pyogenic bacteria. The estimation of antibacterial activity of the ripe fruit & unripe fruit extract were carried out by serial two fold tube dilution techniques. Minimum Bactericidal Concentration of the ripe as well as unripe fruit extracts for the susceptible bacteria were estimated by Recovery plate method. Both the Unripe and ripe fruit extracts exhibited nearly equal and effective activity. As the unripe fruit is devoid of unpleasant odour, the unripe fruit is preferable over the ripe fruit extract
