toxic, bloom‐forming dinoflagellate of global significance. The major sterols were dinosterol (40% of total sterols), dihydrodinosterol (32%), and the rare 4α‐methyl Δ8(14) sterol, amphisterol (23%). A minor sterol, 4α‐methylergost‐24(28)‐enol was also detected (5.0%). The fatty acids had a high proportion of PUFAs (47%), consisting mainly of EPA (20%) and the relatively uncommon octadecapentaenoic
测定了 Cochlodinium polykrikoides 的甾醇和脂肪酸组成,这是一种具有全球意义的有毒、成花甲藻。主要的甾醇是二甾醇(占甾醇总量的 40%)、二氢二氢二甾醇(32%)和稀有的 4α-甲基 Δ8(14)甾醇、两性甾醇(23%)。还检测到少量甾醇 4α-甲基麦角甾醇-24(28)-烯醇 (5.0%)。脂肪酸具有高比例的 PUFA (47%),主要由 EPA (20%) 和相对不常见的十八碳五烯酸 (18:5, 22%) 组成。虽然不太可能对鱼类产生毒性,但这些脂质可能会导致这种藻类对无脊椎动物产生有害影响。
