Ecophysiological responses of the genus Sarcocornia A. J. Scott growing at the Mediterranean Sea coast, Egypt

摘要

Two Sarcocornia species, Sarcocornia fruticosa and Sarcocornia perennis growing at the Mediterranean Coast of Egypt were collected from two salt marshes locations; Port Said and Borg Elarab to study the effect of seasonal variations on secondary metabolites. Total phenols, total flavonoids, organic compounds, fatty acids and antioxidant activity were determined during dry (July, 2017) and wet (March, 2018) seasons. The results revealed that total phenols, total flavonoids, organic compounds and antioxidant activity were increased while fatty acids were decreased in dry season in the two species. S . fruticosa was higher in total phenols, total flavonoids and antioxidant activity than S . perennis specially those growing at Port Said.
