Abstract

Peel extract of Mangosteen (Gacinia mangostana L.) can controll Aspergillus flavus, and Colletotrichum gloeosporioide since the peel contains high total phenolic content. However, different solvents might result in a different extraction yield of total phenolics. This research studied the effect of 4 solvents, acetone, ethanol, methanol, and water on total phenolic content in the fresh and dry peel of mangosteen. Folin-Ciocalteu method was used for total phenolic content analysis. The result demonstrated that mangosteen peel extracted with methanol, ethanol, and acetone contained non significant difference of total phenolic contents in dry mangosteen peel. Extraction of the peel with water resulted in less total phenolic content than other solvents in both fresh and dry magosteen peel. In conclusion, to obtain high total phenolic content, methanol, ethanol, and acetone, should be used for the extraction of total phenolic content from mangosteen peel.
