摘要：

The seasonal variations of polyphenol contents and their antioxidant activities in Corallina officinalis and Corallina elongata were assessed. The highest total phenolic content was recorded during summer in C. officinalis and during autumn in C. elongata, however the highest total flavonoid contents were observed in C. officinalis in the same season but in spring for C. elongata. Antioxidant levels (EC50) were the highest in spring in both species, the same season showed highest total antioxidant capacity in C. elongata but C. officinalis presented the highest value in autumn, we found a positive correlation between total flavonoid content and in both tests for antioxidant activity, the HPLC analysis of the extracts which gave the best results (spring and summer extracts of C. officinalis and spring extract of C. elongata) showed that the 3 extracts contain catechin in large quantities, more coumarin which is found in spring extracts of C. officinalis and C. elongata and myrecitin in summer extract of C. officinalis in second quantity, and caffeine which is in spring extract of C. elongata in third quantity.
