  • Title: Seasonal changes of α-tocopherol in green marine algae (Caulerpa genus).

    Journal: J Food Sci; 2011; 76(5):C775-81. PubMed ID: 22417426.
    Abstract:
    Marine algae are a promising source of beneficial compounds for human use. Among these, pro-vitamin A carotenoids and vitamins B, C, and E stand out. The objective of this study was to investigate seasonal variation of α-tocopherol levels in 5 species of green marine algae of the Caulerpa genus. This research was carried out with both fresh and dry specimens; and, in addition, differences arising as a result of the drying process were examined. Analyses were carried out by high-performance liquid chromatography (HPLC) using an isocratic system and a reversed-phase C-18 column. The distribution of α-tocopherol throughout the year in Caulerpa genus was variable. All samples of both fresh and dried algae contained α-tocopherol, except for the dried C. racemosa from March 2006. The drying process was responsible for losses of α-tocopherol ranging from 21% to 93%.
