Amounts assayed are expressed in mg equivalent of SC (mg SC eq), where each weight equivalent of the extract corresponds to the amount of SC extracted. Et2O-ex, EtOH-ex, Aq-ex and HCl-ex indicate C. gigas SC extracts with diethyl ether, ethanol, water and hydrochloric acid, respectively. FD HCl-ex indicates freeze dried HCl-ex. Data are means of 6 to 15 replicates and error bars represent standard deviations (SD). Letters indicate results of the post hoc Tukey HSD test. Groups connected by the same letter are not significantly different (p≥0.05).
