Abstract

Two green seaweeds Bryopsis pennata Lamour. and Valoniopsis pachynema (Mart.) Bthetarg. collected from the coast of Karachi have been studied for their fatty acid compositions. Altogether 34 fatty acids were identified as methyl esters from them, out of which 9 were saturated and 25 unsaturated acids including 17 monoenoic, 5 dienoic and 4 trienoic acids. They were identified by gas chromatography-mass spectroscopy (GC-MS). Both seaweeds contained exactly the same saturated fatty acids, their unsaturated acids (67.58-71.81%) were greater in proportion than the saturated ones (28.17-32.38%). Tridecatrienoic (28.1%) and palmitic (13.93%) acids occurred in highest amount. Oleic acid was not uniformly present and occurred in small proportion (1.53%).

摘要

对从卡拉奇海岸采集的两种绿色海藻——羽藻（Bryopsis pennata Lamour.）和厚膜藻（Valoniopsis pachynema (Mart.) Bthetarg.）的脂肪酸组成进行了研究。从它们中总共鉴定出34种脂肪酸甲酯，其中9种为饱和脂肪酸，25种为不饱和脂肪酸，包括17种单烯酸、5种二烯酸和4种三烯酸。通过气相色谱 - 质谱联用仪（GC-MS）对它们进行了鉴定。两种海藻所含的饱和脂肪酸完全相同，其不饱和脂肪酸（67.58 - 71.81%）的比例高于饱和脂肪酸（28.17 - 32.38%）。十三碳三烯酸（28.1%）和棕榈酸（13.93%）的含量最高。油酸并非均匀存在，且含量比例较小（1.53%）。
