Figure 6.

Protein content (A,B), phenolic compounds’ content (C,D) and antioxidant activity (E,F) measured in the supernatants resulting from sequential hydrolysis of the insoluble compounds hydrolyzed with pepsin (A,C,E) followed by collagenase (B,D,F) in samples of umbrella and oral arms of Cassiopea andromeda, pre-extracted with PBS followed by 80% EtOH or with 80% EtOH followed by PBS. Protein content is expressed as mg per gram of dry weight (DW), total phenolic content is expressed as µg of gallic acid equivalent (GAE) per g of DW and antioxidant activity is expressed as nmol of Trolox eq. (TE) per g of DW. Data are the mean of three independent experiments performed in triplicate; data are means with ± standard deviation (SD).
