【 摘 要 】

This research was aimed to extract phycocyanin from microalgae Spirulina platensis using an extraction assisted byultrasound irradiation. The extraction was conducted by using variable of extraction time, temperature and ultrasoundfrequency, while ethanol was used as solvent. The results show that the yield of phycocyanin extract was 15.97% at constantfrequency of 42 kHz and 11.24% at constant frequency of 28 kHz, while the soxhlet extraction method obtained yieldat 11.13%. The ultrasound could reduce the extraction time from 4 hrs (conventional) to 20 minutes, while the optimumtemperature of extraction was found at 55°C.
