目的采用气质联用技术分析生长于黑龙江北部地区大兴安岭野生玫瑰花脂肪酸的组成。方法将同一天采摘并储存于相同条件下的野生玫瑰花,采用索氏提取法,以石油醚为溶剂对野生玫瑰花的不同部位萃取得到玫瑰花脂肪酸,经三氟化硼-甲醇酯化后,用气质联用技术进行定性和定量分析。结果野生玫瑰花不同部位(花瓣、花蕊、花托及花萼)的脂肪酸组成不同,花瓣中共检测出14种脂肪酸,其中不饱和脂肪酸相对含量为63.78%;花蕊中共检测出15种脂肪酸,其中不饱和脂肪酸的相对含量为59.1%;花托中共检测出13种脂肪酸,其中不饱和脂肪酸的相对含量为47.02%;花萼中共检测出20种脂肪酸,其中不饱和脂肪酸的相对含量为40.3%。结论野生玫瑰花不同部位(花瓣、花蕊、花托及花萼)的脂肪酸组成不同,花瓣部位富含不饱和脂肪酸,对提升玫瑰花精油的质量,充分利用野生玫瑰花资源提供了参考。
Objective To analyze the composition of wild rose fatty acids in Daxingan Mountains in the northern part of Heilongjiang by GC / MS. Methods Wild rose flowers were collected and stored under the same conditions on the same day. Soxhlet extraction was used to extract rose fatty acids from different parts of wild rose with petroleum ether as solvent. After esterification with boron trifluoride-methanol , Qualitative and quantitative analysis by GC / MS. Results The fatty acid composition of different parts (petals, stamen, receptacle and calyx) of wild rose were different. Fourteen kinds of fatty acids were detected in petals, of which the relative content of unsaturated fatty acids was 63.78%. Fifteen kinds of fatty acids were detected in the stamens. Among them, unsaturated fatty acids The relative content of unsaturated fatty acids was 59.1%. 13 kinds of fatty acids were detected in the receptacle of Torula, the relative content of unsaturated fatty acids was 47.02%, 20 kinds of fatty acids were detected in the calyx, and the relative content of unsaturated fatty acids was 40.3%. Conclusion The composition of fatty acids in different parts of wild rose (petal, stamen, receptacle and calyx) is different. The petal part is rich in unsaturated fatty acid, which provides a reference for improving the quality of rose essential oil and making full use of wild rose resources.
