标题:Antioxidant and antimicrobial activities of Halocnemum strobilaceum fractions and their related bioactive molecules identification by GC/MS and HPLC
摘要:Polar and apolarfractions of Halocnemum strobilaceum shoot extracts were evaluated for their phenolic contents and biological activities. HPLC and GC/MS methods have been implemented for phenolics and fatty acids content identification, respectively. Results showed that phenolic contents and antioxidant activities varied considerably according to the fraction nature. In fact, the apolar fraction contains two folds higher flavonoïd and tannin contents (1.87 and 0.83mg CE.g-1DW, respectively) compared to the polar one. In contrast, total polyphenol content was superior in the polar fraction. The important phenolics content in chloroformic extract was correlated to the best antioxidant activity such as total antioxidant activity (5.54mg GAE.g-1DW), antiradical activity against DPPH radical.
