Abstract

Garcinia mangostana fruit is one of the most popular fruit and known as a tropical fruit that has high
nutrition value and widely cultivated in the tropical rainforest of some Southeast Asian nations. The
main objectives of this research were to identify the composition of extracted xanthones and to
determine the antioxidant activity, total phenolic content, moisture content and antimicrobial activity
of encapsulated Garcinia mangostana pericarp. Encapsulation process was done by using freeze
drying technique. Antioxidant activity, total phenolic content, moisture content and antimicrobial
activity of encapsulated xanthones analysis were conducted. The amount of xanthones was detected
at range of 515 to 4000 cm⁻
1
through Fourier transforms infrared spectroscopy (FTIR). The highest
value of radical scavenging activity for non-encapsulated xanthones was 82.69% whereas 88.01% for
encapsulated xanthones. The total phenolic content (TPC) was found 5.240 mg GAE/g and
6.359 mg GAE/g for non-encapsulated and encapsulated samples, respectively. In conclusion,
encapsulated xanthones from Garcinia mangostana pericarp has high antioxidant activity and
antibacterial properties which has potential to the manufacturing functional food, cosmeceutical and
pharmaceutical industries.
