蜡梅种子油化学成分研究

Analysis of essential oils in seeds from Chimonanthus Praecox by GC/MS

采用气相色谱/质谱联用技术测定了蜡梅种子油的化学成分。从中鉴定出31种化合物,其中相对含量大于1.0%的有14种,大于2.0%的有9种,大于8.0%和12.0%的分别有2种;大于21.0%的只有1种。有3种保留时间不同的组分尚未确定。实验结果显示油酸(21.7%)、1'-甲基-蜡梅碱(12.74%)、亚油酸(12.62%)、软脂酸(8.69%)、蜡梅碱(8.15%)、、石竹烯(3.90%)、亚麻酸(3.88%)、邻苯二甲酸二异丁酯(2.30%)、硬脂酸(2.17%)是蜡梅种子油的主要成分,其合计相对含量达到76.15%。

The essential oils from seeds of Chirnonanthus praeco were analyzed by GC,/MS, thirty-one compounds in the oils were identified. There are 14 compounds＇ relative mass is more than 1.0% 9 compounds＇ relative mass is more than 2.0%; 4 compoundg relative mass is more than 8. 0%and 12.0% respectively, and only a compound＇s relative mass is more than 21.0%. The results showed that oleic acid （21. 70% ）, 1,-methyl-calycanthine（ 12.74 % ）, linoleic acid （ 12. 62%）, hexadecanoic acid （ 8. 69% ）, calycanthidine （8.15%）, caryophyllene（3, 90%）, linolenic acid（3.88%）, phthalie acid diisobutyl ester（2.30%） and stearic acid （2. 17%） were the major components of the essential oils, their total up is 76.15%.
