Identification of Anti-Lung Cancer Extract from Chlorella Vulgaris C-C by Antioxidant Property Using Supercritical Carbon Dioxide Extraction

H.-A. Chen, T.-W. Chen, H.-M. Wang & J.-L. Pan
In this study, supercritical carbon dioxide extraction (SC­CO2) technology was developed to extract the active components (such as antioxidants) from a novel microalga, Chlorella vulgaris C­C, due to its superior advantages over conventional solvent or ultrasonic extraction methods. Using SC­CO2 and ultrasonic extractions, the polyphenol contents of C. vulgaris C­C were 13.40 and 0.46 (mg gallic acid/g lyophilized extract), respectively. The flavonoid content obtained from SC­CO2 (3.18 mg quercetin/g lyophilized extract) was also significantly higher...
