Voss Oriental Journal of Chemistry Salacca zalacca (Gaertn.) Voss or snake fruit is a species of palm tree native to Southwest Java and North Sumatra in Indonesia. It is known as one of the exotic fruits in Malaysia. It has a pleasant pineapple, pear and banana-like aromas. Due to its pleasant aroma, Salacca zalacca has potential in the perfumery and pharmaceutical industries.

The percentage Yields of SFE extracts were higher (10 MPa, 30°C: 0.2577 %; 25 MPa, 30°C: 0.2375 %; 30 MPa, 30°C: 0.2721 %) than the steam distillation (0.1855 %), diethyl ether (0.5692 %), hexane (0.0511 %) and DCM (0.1358 %) solvent extracts. However, SFE produced a lower yield (40 MPa, 70°C: 0.2721 %) than the diethyl ether solvent extraction (0.5692 %) but SFE was found to be more efficient and environmentally friendly. 35 6 1669-1677
