Study on Antimicrobial and Antioxidant Activities of Selected Fruits Waste

Abstract

The fruits wastes like peel and crown leaves have been a valuable source of bioactive compounds and they are useful for human health. Since thousands of years, the practice of Ayurvedic medicine and Unani herbal drug, are used is customary medicines and attributed over all positive health by these medicines. However the Fruits waste like peels and crown leaves etc are discarded and least exploited. This adds to a lot of pollution problem too if they are not disposed off judiciously. Fruits waste like pomegranate peels, banana peels, sweet lime peels, pineapple crown leaves, corn husk and custard apple peels are used as a source for isolation of the bioactive compounds in present the study. These fruits waste contain various bioactive ingredients and it would be used to cure different diseases. The fruit peels and crown leaves extracts for antimicrobial properties could be a great significance in therapeutic treatments. The dried powdered peel extract in various solvent like methanol, ethanol, chloroform, hexane and their phytochemicals revealed the potency of these extract. Fruits waste extract of peels and crown leave are rich source of the phytochemicals and it have therapeutic potency as antimicrobial agents. Pomegranate peels, banana peels, sweet lime peels, pineapple crown leaves, corn husk and custard apple peels extract of 80mg/ml concentration against the bacteria gram-positive bacteria, Bacillus subtilis (NCIM 2196) and Gram-negative bacteria Escherichia coli (NCIM 2065) and Pseudomonas aeruginosa (NCIM 5029). Maximum inhibitory effect against Escherichia coli, Bacillus subtilis and Pseudomonas aeruginosa, methanol and ethanol extracts of pomegranate peels exhibited the maximum inhibition activity of methanol ±16mm against Escherichia coli compared to other extract like ethanol ±15 mm, chloroform ±15mm and hexane ±15mm, in case of Escherichia coli, and Pseudomonas aeruginosa. Sweet lime peels extract exhibited the maximum inhibition activity of chloroform ±11mm against Pseudomonas aeruginosa compared to the
