  气相色谱/电子捕获负离子质谱仪用于定量测定牛乳脂肪中的2-和3-羟基脂肪酸。

  摘要：

  2-和3-羟基脂肪酸（2-和3-OH-FAs）是鞘脂和细菌中报告的生物活性物质。人们对它们在食物中的存在知之甚少。因此，开发了一种适用于牛乳脂肪中痕量OH-FAs测定的方法。将OH-FAs（和样品中的常规脂肪酸）转化为甲酯，然后用五氟苯甲酰氯（PFBO）将羟基衍生化，得到PFBO-O-FA甲酯。这些具有强电子亲和力的衍生物是通过在所选离子监测模式下使用电子捕获负离子通过气相色谱与质谱联用确定的（GC / ECNI-MS-SIM）。事实证明，该方法对PFBO-O-FA甲酯具有高度的敏感性和选择性。为了分析样品，使用了两个内标。为此，9，来自2-OH-18：1（9 c）甲酯的10-dideutero-2-OH-18：0甲酯（ISTD-1）以及3-PFBO-O-12：0的乙酯-2）被合成。ISTD-1用作回收标准，而ISTD-2用于GC / MS测量。整个样品净化包括加速溶剂萃取干牛乳，添加ISTD

  Fatty acid ester derivatives and a process for their production from unsaturated fatty acids are disclosed. The process comprises: a) reacting an unsaturated fatty acid or an ester thereof having one or more sites of unsaturation, with an epoxidation reagent to form a fatty acid epoxide wherein at least one of the sites of unsaturation of the fatty acid or fatty acid ester is converted to an oxirane ring; and b) reacting the fatty acid epoxide produced in a) with a carboxylic acid to form a hydroxy fatty acid ester derivative wherein the oxirane ring is opened and converted to a hydroxy ester comprising a hydroxyl group at one carbon of the opened oxirane ring and an ester of the carboxylic acid at the other carbon of the opened oxirane ring.

  A method is described for treating soil to increase plant growth or improve the health of plants, wherein an aqueous solution of a bio-derived surfactant obtained from natural lipids has pesticidal effects. In some embodiments, the method can be used against soil pests such as at least one of nematodes, soil-dwelling insects, and weeds. The invention also pertains to methods for applying bio-derived surfactants to crops and other plants or to the soil used for such plants in order to reduce the need to apply environmentally unfriendly pesticides substances.
