Abstract

Syzygium is a genus belongs to Myrtaceae. One species of the genus is cashew rose (Syzygium jambos (L.) Alston) which contains secondary metabolites, such as flavonoids, tannins, steroids/terpenoids, alkaloids and saponins. This study aimed to find the content of these secondary metabolites using thin layer chromatography (TLC) and its antioxidant activity. The simplicia of cashew rose leaves was extracted by maceration using methanol as a solvent for 64 hours. This results in methanolic extract of cashew rose leaves. The resulted chromatogram using n-hexane and ethyl acetate eluent showed that the methanolic extract of leaves cashew rose has at least five compounds with retention value (Rf) consecutively were 0.32, 0.36, 0.68, 0.72, and 0.84. The stains could be seen in UV light 356 nm, but not in UV light 254 nm. It can be concluded that these compounds were classified as nonfenolic compound. The antioxidant test of methanolic extract of cashew rose leaves showed a very strong antioxidant activity with IC50 value of 13,554 ug/mL.
