摘要:

采用顶空—固相微萃取结合气相色谱—质谱联用技术,对芍药属19个组间杂种花瓣的挥发性成分进行了分析。共检测到84种挥发性成分,包括萜类25种,苯环型/苯丙素类14种,脂肪酸衍生物29种,杂环类12种和含氮类4种。定量分析结果表明,不同杂种的挥发性物质含量存在显著差异,‘史密斯黄’和‘凯丽的记忆’中总挥发性物质含量显著高于其他杂种,分别为97.47和97.43 μg · g-1 · h-1;而‘红天堂’中含量最低,仅有8.43 μg · g-1 · h-1。萜类化合物是19个杂种的主要挥发性物质,其中β-石竹烯和芳樟醇是其主要香气成分,根据其构成特点,可分为以芳樟醇为主,以β-石竹烯为主,同时具有较高含量的芳樟醇和β-石竹烯,以香叶醇为主和挥发性物质含量均较低这5类,不同杂种中香气物质的构成特点对其花香的形成具有重要作用。

Abstract:

In order to better understand the volatile compounds of intersectional hybrids of Paeonia(IHP),headspace-solidphase microextraction(HS-SPME)combined with gas chromatography-mass spectrometry(GC-MS)was used to analyze the volatiles of the petals among 19 intersectional hybrids of Paeonia cultivars. A total of 84 volatile compounds were identified,comprising of 25 terpenoids,14 benzenoids/phenylpropanoids,29 fatty acid derivatives,12 miscellaneous cyclics and four nitrogen- containing compounds. The results from quantitative analysis showed that the content of volatile compounds varied significantly among IHP cultivars. The total content of volatiles in‘Smith Family Yellow’and‘Callie’s Memory’were higher than other cultivars,which were 97.47 and 97.43 μg · g-1 · h-1,respectively. By contrast,‘Scarlet Heaven’had the lowest content,namely 8.43 μg · g-1 · h-1. Terpenoids were the main volatile components of 19 IHPs,in which β-caryophyllene and linalool were the dominant volatile components. Specifically,they were divided into five groups,in which linalool,β-caryophyllene,both β-caryophyllene and linalool,geraniol were the predominant,respectively. The remaining group emitted extremely low content of volatiles. The varied proportion of volatiles especially β-caryophyllene and linalool between IHPs played an important role in the formation of floral scent.
