Abstract

Fatty acids have many important biochemical properties such as energy, metabolic and other structural activities. Orchids, which are among the common species worldwide, are used as beverages, food additives and drugs in societies. Orchid seeds are one of the smallest seeds that do not contain nutrient tissue naturally and are rich in fatty acids. Plants dried at room temperature were extracted using chloroform/methanol (2:1). Their methyl esters were analyzed using a Gas Chromatography device. As a result of the analysis, a total of 16 fatty acids were determined. Out of these, palmitic acid (16:0), oleic acid (18:1n-9) and linoleic acid (18:2n-6) were found as major fatty acids. Other fatty acids, myristic, pentadecanoic, stearic, linolenic, arachidonic and docosapentaenoic acid were detected in trace amounts. When the percentage distribution of palmitic acid was considered, it was observed that it ranged between 16.76% and 25.32%, and the highest one was in Anacamptis collina. It was also found that the distribution of stearic acid was similar among species. Oleic acid exhibited the highest distribution as percentage in Orchis simia (27.33%), Orchis mascula subsp. pinetorum (25.16%) and Orchis spitzelii (25.66%). Linoleic acid showed different distribution among species. The lowest percentage was found in Orchis tridentata (15.13%), while the highest one was in Orchis mascula subsp. pinetorum (34.02%). This study carried out on fatty acids is a part of the study on the use of natural bioactive products and fatty acids, hoping to be used in industrial applications.
云南省内几种兰花种子的脂肪酸分析
脂肪酸具有许多重要的生化特性,如能量、代谢和其他结构活性。兰花是世界上常见的植物之一,在社会上被用作饮料、食品添加剂和药物。兰花种子是最小的种子之一,天然不含营养组织,富含脂肪酸。在室温下干燥的植物用氯仿/甲醇(2:1)提取。用气相色谱法分析了它们的甲酯。作为分析的结果,共确定了16种脂肪酸。其中,棕榈酸(16:0)、油酸(18:1n-9)和亚油酸(18:2n-6)是主要的脂肪酸。其他脂肪酸、肉豆蔻酸、五酸、硬脂酸、亚麻酸、花生四烯酸和二十碳五烯酸也被微量检测到。考虑棕榈酸的百分比分布,棕榈酸的含量在16.76% ~ 25.32%之间,以羊角蟹最高。硬脂酸在不同种间的分布也很相似。油酸分布比例最高的是黄兰花(27.33%)、阳根兰花(27.33%)和阳根兰花(27.33%)。松林(25.16%)、野兰科(25.66%);亚油酸在不同种间分布不同。其中,三叶兰(15.13%)和雄性兰(15.13%)的比例最低。pinetorum(34.02%)。本次对脂肪酸的研究是天然生物活性产品和脂肪酸利用研究的一部分,希望能在工业上得到应用。
