用索氏提取法提取脂溶性成分,GC-MS联用法结合计算机检索首次对开封产两个黄色菊花品种(春日剑山和麦浪)的脂肪酸成分进行了分析鉴定。结果从春日剑山和麦浪中分别鉴定出了45和35种化合物,其中脂肪酸成分为21和11种,用气相色谱峰面积归一法测定了各组分的相对质量分数,鉴定成分各占其色谱总馏分出峰面积的93.99%和94.00%。两者主要脂肪酸为肉豆蔻酸、棕榈酸、亚麻酸、棕榈油酸、顺-9-顺-12-亚油酸和月桂酸。还检测到具有活性的α-香树脂醇(8.57%)、β-香树脂醇(7.47%)和(3β,5α,24S)-7-豆甾烯-3-醇(19.48%)仅存在于麦浪中,是与春日剑山有明显差别的药效成分。该文报告工作的新颖性已为河南大学图书馆2008年8月14日出具的第CX2008005号《科技查新报告》所证实。
Soxhlet extraction was used to extract fat-soluble components. GC-MS combined with computer search was the first to analyze and identify the fatty acid composition of two yellow chrysanthemum varieties produced in Kaifeng (Jingri Jianshan and Mailang). RESULTS: 45 and 35 compounds were identified from Jianshan and Mailang in Chunri. Among them, 21 and 11 fatty acids were used. The relative mass fraction of each component was determined by gas chromatographic peak area normalization method. The total peak area of the chromatogram was 93.99% and 94.00%. The two main fatty acids are myristic acid, palmitic acid, linolenic acid, palmitoleic acid, cis-9-cis-12-linoleic acid and lauric acid. It was also detected that active α-arosciol (8.57%), β-macromol (7.47%), and (3β, 5α, 24S)-7-sitosterol-3-ol (19.48%) exist only in Mai Lang is a medicinal ingredient that is significantly different from that of Chunri Jianshan. The novelty of this article’s report has been confirmed by the “Science and Technology Innovation Report” No. CX2008005 issued by the Henan University Library on August 14, 2008.
