将冷冻干燥的微藻小球藻样品在40和55摄氏度的温度和高达35.0 MPa的压力下置于超临界CO2中。这项研究是在整个和粉碎的藻类上进行的。前者类胡萝卜素和其他脂类的提取率较低，而后者的提取率显著提高。类胡萝卜素和其他脂质的提取率随压力的增加而增加。类胡萝卜素在油中的分数也更大，在较高的压力。另一方面，超临界CO2萃取类胡萝卜素相比，有利的己烷和丙酮提取。
Freeze-dried samples of the microalga Chlorella vulgaris were submitted to supercritical CO2 at temperatures of 40 and 55 degrees C and pressures up to 35.0 MPa. This study was carried out on whole and crushed algae. The extraction yields of carotenoids and other lipids were low in the former case and improved significantly in the latter one. Extraction yields of carotenoids and other lipids increased with pressure. The fraction of carotenoids in the oil was also greater at higher pressures. On the other hand, supercritical CO2 extraction of carotenoids compared favourably with hexane and acetone extractions.
