Antioxidant and antimicrobial properties of Garcinia mangostana

Abstract

Aim of this study is to present microbiological quality, and antimicrobial and antioxidant activity of the mangosteen fruit in two forms: freeze-dried powder and fresh fruit. During the identification of the mangosteen microbiota using a MALDI-TOF MS Biotyper mass spectrophotometer, the presence of B. cereus and Saccharomyces spp. has been detected. The best antimicrobial activity was achieved against Micrococcus spp. Mangosteen fruit ( Garcina mangostana ) is characterized by a high content of polyphenols at the following levels: fresh fruit 3.22 ±0.68 mg GAE.g −1 ; powder form 2.17 ±0.64 mg GAE.g −1 . Mangosteen shows a high antioxidant capacity of the fruit in the two forms presented in the work. It was 21.18% (fresh fruit) and 14.46% (freeze-dried fruit). Mangosteen also shows an antibacterial activity in relation to the strains of bacteria tested in our work.
