Abstract

Syzygium genus in Myrtaceae family is a rich source of phytochemical constituents that possess various bioactivities. One of well-known species of this genus, Syzygium aqueum, has been already utilized as traditional medicine. This plant is cultivated in countries of tropical regions of the world such as Malaysia and Indonesia. The aim of this study was intended to isolate phytochemical constituents from the stem bark of S. aqueum. To date, there have been no reports of chemical substances isolated from the stem bark of this plant. The powder of the stem bark was extracted followed by partitioned in order to obtain n-hexane extract which then was separated using silica gel column chromatographic several times until the pure compounds were resulted. The isolated compounds were identified by spectroscopie method including Fouirer Transform Infrared (FTIR) and nuclear magnetic resonance (NMR) and were known as 2,4-Di-tert-butylphenol & butyrospermol 3-?-O-palmitate, respectively. The spectoscopie data of those compounds were compared with references.
