Abstract
Crude lipids extracted from the adipose tissues of some commercialized freshwater catfish, including the Mekong giant catfish (Pangasianodon gigas), striped catfish (Pangasianodon hypophthalmus) and hybrid catfish (Pangasius larnaudii x Pangasianodon hypophthalmus) were carried out. Their saturated fatty acid and unsaturated fatty acid contents were not much different, but their polyunsaturated fatty acid contents were obviously different. Their n-3 fatty acid contents were 15.58, 0.83 and 4.36 g per 100 g, respectively, and their eicosapentaenoic acid (EPA):docosahexaenoic acid (DHA) contents were 3.23:4.24, 0.07:0.13 and 0.65:2.72 g per 100 g, respectively. Their n-6 fatty acid contents were 6.36, 9.19 and 8.77 g per 100 g, respectively. They were in solid and semi-solid form at room temperature with certain different physical properties. No sign of toxicity was observed for 14 days in female Wistar albino rats after receiving a dose of crude lipids at 5000 mg/kg. Their antioxidant activities by ABTS assay were 3.21, 4.53 and 6.00 mM Trolox per 1 g, respectively.
