    文冠果花精油组分研究

    Essential oil composition of Xanthoceras sorbifolium flower

    • 摘要:
        目的  研究3种花色文冠果花精油化学组成,探究精油中化合物构成的异同。
        方法  以白色、粉色、紫色3种花色的文冠果花瓣为原料,提取得到文冠果花精油,利用气质联用技术(GC–MS)对精油的成分进行分析。
        结果  不同颜色的文冠果花精油得率在0.042%~0.050%之间,得率较高的是白色花,为(0.048 ± 0.002)%。3种花色精油中共检测到96种化合物,其中白色花精油检测到的62种化合物,其主要成分为二十一烷(31.46%)、二十四烷(14.16%)、二十烷(7.55%)、壬醛(7.28%)、诱虫烯(4.84%)、植酮(4.83%);粉色花精油检测到的65种化合物,其主要成分为二十一烷(31.96%)、四十四烷(20.83%)、壬醛(6.72%)、十八烷(3.86%)、植酮(3.76%)、十六烷(3.30%);紫色花精油检测到的47种化合物,其主要成分为二十一烷(30.33%)、三十六烷(25.09%)、二十四烷(14.44%)、二十烷(7.42%)、叶绿醇(3.95%)、十六烷(3.28%)。烃类物质在3种精油中的百分含量显著高于其他几类物质(P < 0.05)。对3种精油中的29种共有化合物进行主成分分析(PCA),可简化为2个主成分,累计方差贡献率达98.112%,可反映样品的绝大部分信息。
        结论  不同花色文冠果花精油的得率和化合物组成存在一定差异,在得率方面,白色花精油高于其他花色,但差异并不显著(P > 0.05);在精油组分方面,粉色花精油化合物种类多于其他花色精油,每种精油中的主要化合物种类与百分含量也存在较大差异。本研究为文冠果花精油的开发利用提供了数据支撑。

       

      Abstract:
        Objective  The chemical composition of essential oil from flowers with different colors of Xanthoceras sorbifolium was studied, and the similarities and differences of the compounds in the essential oil were investigated.
        Method  The essential oil was extracted from the petals of X. sorbifolium in white, pink and purple. The components of essential oil were analyzed by gas chromatography-mass spectrometry (GC-MS).
        Result  The yield range of essential oil of the three flowers was between 0.042%−0.050%. The higher yield was white flower, which was (0.048 ± 0.002)%. The 96 volatile compounds were detected in three kinds of essential oil. Among the 62 compounds detected by white flower essential oil, the main components were heneicosane (31.46%), tetracosane (14.16%), eicosane (7.55%), 1-nonanal (7.28%), muscalure (4.84%), perhydrofarnesyl acetone (4.83%); among the 65 compounds detected by pink flower essential oil, the main components were heneicosane (31.96%), tetratetracontane (20.83%), 1-nonanal (6.72%), octadecane (3.86%), perhydrofarnesyl acetone (3.76%), hexadecane (3.30%); among the 47 compounds detected by purple flower essential oil, the main components were heneicosane (30.33%), hexatriacontane (25.09%), tetracosane (14.44%), eicosane (7.42%), phytol (3.95%), hexadecane (3.28%). The content of hydrocarbons in the three kinds of essential oil was significantly higher than that of other types of substances (P < 0.05). Principal component analysis (PCA) of 29 common compounds in the three kinds of essential oil can be simplified into two principal components, and the cumulative variance contribution rate was 98.112%, which can reflect most of the information on the samples.
        Conclusion  There are some differences in the yield and compound composition of the essential oil in X. sorbifolium flower with different colors. In terms of yield, white flower essential oil is higher than other color flower essential oil, but the difference is not significant (P > 0.05). In terms of essential oil components, there are more types of compounds in pink flower essential oil than that in other flowers, and there are also large differences in the types and relative contents of the main compounds in each kind of essential oil. This study provides data support for the development and utilization of essential oil extracted from the petals of X. sorbifolium.
