There is growing interest in the bioactive components of marine algae due to their biomedical importance. In this study, a compressional-puffing (CP) process was adopted to pretreat algal samples of Sargassum crassifolium (SC), and the bioactive components of non-puffed and compressional-puffed SCs were extracted using aqueous-ethanol solution. Two extracts, namely, NPSC (non-puffed) and CPSC (compressional-puffed) were obtained, and their compositions were analyzed and compared. It was found that the composition of CPSC extract was different from that of NPSC. Further biological activity studies revealed that extracts of both NPSC and CPSC exhibited antioxidant activity, but only NPSC extract showed anti-inflammatory activity. In growth inhibition experiments, it was found that CPSC extract had a more cytotoxic effect in Hep G2 hepatoma cells and induced more DNA fragmentation of Hep G2 hepatoma cells compared with the effects exerted
