Abstract: Tomato (Solanum lycopersicum L.) is one of the most important vegetables worldwide because of its high consumption, year round availability and large content of health related components. Tomatoes contain a variety of phytochemicals such as lycopene, -carotene, vitamin C, quercetin glycosides, naringenin chalcone and chlorogenic acid and have good health protective effects. The present work is to search antimicrobial activity of methanol (E1),ethanol (E2),acetone(E3),chloroform (E4) and ether (E5) extracts from tomato fruits. The antibacterial property was evaluated by using agar diffusion method using bacterial cultures Staphylococcus aureus (ATCC 9144),Bacilus subtilis (ATCC 6633), Pseudomonas aeruginosa (ATCC 27853), Escherichia coli (ATCC 25922) and fugal culture of Aspergillus niger (ATCC 9029), Aspergillus flavus (ATCC 204304), Candida albicans (ATCC 10231). By observing it was found that most of the extracts executed moderate to good antimicrobial activity against the tested micro-organisms. The extracts were active against all the tested microorganism for anti-bacterial activity with range of MIC values for S.aureus ( MIC: 15-39 µg /ml ), E.coli ( MIC: 16-38 µg /ml) ,P.aeruginosa (MIC:15-39 µg /ml) and B.subtilis ( 14-39 µg /ml) The extracts were active against all the tested microorganism for anti-fungal activity with the range of MIC values for A.niger (MIC :17-39 µg/ml),A.flavus (18-37 µg/ml) and C.albicans (16-35 µg/ml).
