Abstract
Annona squamosa (custard apple) or also called Sugar Apple. It is native to the tropical Americas
and West Indies, but the exact origin is unknown. It is now the most widely cultivated of all the
species of Annona, being grown for its fruit throughout the tropics and warmer subtropics, such as
Indonesia, Thailand, and Taiwan; it was introduced to southern Asia before 1590. There are two
varieties of custard apple which were available in the local Malaysian market. In the present study
we aimed to carry out comparative antioxidant activity of methanolic extract of both custard apple
fruits by using 2,2-diphenyl-1-picryl-hydrazyl (DPPH) method. The results showed that the
methanolic extract of red custard apple showed better antioxidant activity than methanolic extract of green custard apple. However, the standard ascorbic acid showed better antioxidant activity than
both the extracts. In conclusion, the red custard apple is good candidate for further investigation.
