FATTY ACID COMPOSITION AND PROSTAGLANDIN CONTENT OF THE RED SEAWEED Gracilaria sp. FROM INDONESIA
Abstract: High content of
polyunsaturated fatty acids (PUFAs) such as arachidonic and eicosapentaenoic
acids are typical for the red alga. Analysis of fatty acid composition and
prostaglandin content was conducted in the red alga Gracilaria sp. from
Indonesia. Total lipid of the alga was extracted with CHCl3-MeOH (2:1, v/v).
Analysis of the fatty acids composition was performed on gas chromatography
(GC) equipped with omega wax column (30 m x 0,32 mm i.d., Supelco, PA, USA) and
analysis of prostaglandins were carried out by HPLC on ODS column (Mightysil
RP-18 GP, 250 mm x 4.6 mm, 5 μm). The content of fatty acids high for were palmitic
acid (50%) and arachidonic acid (26.9%), whereas prostaglandin E2 was
identified and found lower concentration (44.2 μg/gram total lipid).
