Total phenolic compounds in jellyfish extracted with phosphate buffered saline (PBS), 80% methanol and 80% ethanol from freeze-dried tissues of Aurelia sp.1, C. tuberculata and R. pulmo. Data are expressed as μg of gallic acid equivalents (GAE) per gram of dry weight and are means of three independent experiments performed in triplicate, bars represent mean ± standard deviation (SD). A,B,C: the different capital letters indicate differences among species for the same extraction type; a,b,c: the different lower case letters indicate significant differences among extracts in the same jellyfish species, (p < 0.05).
