Antimicrobial and antioxidant activities of selected underutilized fruits in Malaysia / Nurul ‘Amirah Aziz

Underutilized fruits are defined as fruits that are rarely eaten, unknown and unfamiliar because some of the species only exist at a certain region. There is a lack of the antimicrobial and antioxidant studies on underutilized fruits. Therefore, this study was carried out to examine the antimicrobial and antioxidant activities of the methanolic extracts of seven underutilized fruits namely Sonneratia caseolaris, Phyllanthus acidus, Averrhoa bilimbi, Spondias dulcis, Cynometra cauliflora, Barrington racemosa and Syzygium malaccense. The antimicrobial activities were determined by using the Kirby-Bauer disc diffusion method at four concentrations of 200 mg/ml, 300 mg/ml, 400 mg/ml and 500 mg/ml
