Summary: | The work focuses on the study of two brown algae Dictyota dichotoma and
Dictyopteris membranacea. Extracts obtained by different organic solvents
(dichloromethane, hexane, acetone, methanol, chloroform) were screened for
their DPPH antiradical activity, whereas essential oils obtained by steam
distillation were chemically characterized by GC-MS. Steam distillation
yielded 0.07 and 0.095% of the essential oils for Dictyota dichotoma and
Dictyopteris membranacea, respectively. The chemical screening of the
essential oils of Dictyopteris membranacea and Dictyota dichotoma showed
similar chemical profiles. Namely, trans-anethole showed to be the main
component in both studied oils, yielding 12.28% and 10.70% for Dictyopteris
membranacea and Dictyota dichotoma, respectively. Antioxidant activity of
extracts was expressed by IC50 values and was in the range 0.375-1.72 mg/ml. |
