Abstract

Quantitative determination of fucoxanthin was made in the ontogenetic series of 1st order branches of the brown alga Cystoseira barbata (Stackh.) C. Agardh growing in upper sublittoral zone of Martyn Bay (Black Sea coast of Crimea). The greatest content (3 mg/g dry mass) was characteristic of the branches 2 – 3 months old. Total amount of this carotenoid which natural Cystoseira can hold is evaluated from 508 to 1810 mg per square meter of the sea bed.

Keywords: Brown alga, Cystoseira, fucoxanthin, Black Sea
