Melilotus officinalis%fatty acid%GC-MS
利用索氏提取法对黄花草木樨油脂进行提取,油脂经饱和氢氧化钾-甲醇钠皂化,甲醇-硫酸甲酯化后,采用气相色谱-质谱联用法(GC-MS)分析,鉴定出13种脂肪酸,并用峰面积归一法测定各组分相对含量,结果表明,黄花草木樨中含有大量的不饱和脂肪酸,各部位所含主要脂肪酸有明显差异,根、叶、种籽中主要的脂肪酸分别为油酸、棕榈酸及亚麻酸、亚油酸,脂肪酸含量比例分别为10.42%、5.87%、2.87%、17.51%。黄花草木樨植株和种籽中均含有多种脂肪酸成分,为进一步完善和开发黄花草木樨脂肪酸的系统研究提供参考。
利用索氏提取法對黃花草木樨油脂進行提取,油脂經飽和氫氧化鉀-甲醇鈉皂化,甲醇-硫痠甲酯化後,採用氣相色譜-質譜聯用法(GC-MS)分析,鑒定齣13種脂肪痠,併用峰麵積歸一法測定各組分相對含量,結果錶明,黃花草木樨中含有大量的不飽和脂肪痠,各部位所含主要脂肪痠有明顯差異,根、葉、種籽中主要的脂肪痠分彆為油痠、棕櫚痠及亞痳痠、亞油痠,脂肪痠含量比例分彆為10.42%、5.87%、2.87%、17.51%。黃花草木樨植株和種籽中均含有多種脂肪痠成分,為進一步完善和開髮黃花草木樨脂肪痠的繫統研究提供參攷。

Amonds oil from Melilotus officinalis was obtained using Soxhlet extractor to method, and the a-monds oil was saponified with saturated KOH-Methanol.The mixed fatty acids were methylated by methanol-H2SO4. The fatty acids in the Melilotus officinalis were analyzed by GC-MS. Thirteen fatty acids were identified, and the relative contents of constituents .The Results show that the Melilotus officinalis contain high contents of unsaturated fattyacid.The performances of the various parts of fatty acids were not uni-form. There were oleic acid(10.42%)in the root, pamitic acid(5.87%)in the Leaves, linolenic acid(2.87%)and linoleic acid(17.51%) in the seeds. There were some important fatty acids in Melilotus officinalis and seeds. These results provided theoretical basis for chemical constituent research of Melilotus officinalis and future extent research.
