Abstract
Andaliman (Zanthoxylum acanthopodium DC.) a plant beloing to the Zanthoxylum genus is widely found in North Sumatra. Andaliman has been traditionally used by local people to treat various diseases. Several secondary metabolites reported from the genus Zanthoxylum include coumarins, flavonoids, lignans, terpenoids, steroids, amides, alkaloids and phthalate derivatives. Differences in geographical location and the ecosystem where a plant grows can result in different types of secondary metabolites. Therefore, it is interesting to conduct research on the isolation of secondary metabolites from Andaliman originating from North Sumatra. This study aimed to isolate and determine the structure of the secondary metabolites contained in the nonpolar fraction of the Andaliman stem wood from North Sumatra. The methods used in this study included extraction and fractionation using n-hexane, chloroform, and ethyl acetate respectively. The n-hexane fraction was then separated and purified using vacuum liquid chromatography (VLC), gravity column chromatography (GCC) and monitored using thin layer chromatography (TLC). The determination of structure was carried out using Nuclear Magnetic Resonance (NMR) and Fourier Transform Infra Red (FTIR) spectroscopies. The pure isolate was obtained as a yellow oil of 466.1 mg. Based on FTIR and NMR analyses as well as a comparison of spectroscopic data with literature, the isolate was identified as a phthalate derivative, namely di(2-ethylhexyl)phthalate.
