Abstract

Ulam refer as a fresh green salad by Malaysians and usually eaten with a bowl of
rice as a side dishes. The salads are very good against some diseases and had
positive effects that lies in some chemical substances inside the plants such as
flavonoids and phenolic compounds that contributes to its antioxidants properties.
The present study was to analyse the concentration of antioxidant in different types
of selected ulam that was available at the Malaysia market using Ferric Reducing
Antioxidant Power (FRAP) assay. The ulam samples were analysed by using Uv Vis
spectrophotometer at wavelength 593 nm. A sample of ulam known as
Anarcardium occidentade (Jambu Gajus) showed the highest antioxidant activity
and the lowest was Morinda citrifolia (Mengkudu Besar). The study also was
conducted to compare the amount of antioxidant content between the shoots and
the leaves of the selected ulam. Based on the five samples studied, it founds that
three of the samples have higher antioxidant activity at their shoots compared to the
leaves. Another two have higher antioxidant activity at their leaves compared tom
the shoots.
