摘要
为了探明不同茶梅品种花朵挥发性成分的差异,该研究采用固相微萃取和气相色谱-质谱联用技术,分析了6个茶梅品种花朵挥发性成分及其相对含量。结果表明:‘冬星’挥发性成分为29种,‘小玫瑰’24种,‘冬玫瑰’42种,‘昭和之荣’25种,‘新乙女’31种;5种茶梅品种花朵挥发性成分及相对含量有较大差异,但其主体特征成分均为苯乙酮、顺式-芳樟醇氧化物及芳樟醇;成分分类以醛酮类和醇类为主。完全重瓣型茶梅‘富士之峰’挥发性成分为21种;主体特征成分分别是顺式-芳樟醇氧化物、丁香醇、环己酮和十四烷;成分分类以醇类为主,其次为烷烃类。不同茶梅品种花朵挥发性成分化合物种类和相对含量差异较大;雄蕊、花瓣是挥发性成分释放的主要部位。
This study aimed to determine the difference of the volatile components in flowers of six Camellia sasanqua cultivars by solid phase micro-extraction and gas chromatography-mass spectrometry(GC-MS).The results showed that there were 29 components identified in‘Dongxing’,24 in‘Xiaomeigui’,42 in‘Dongmeigui’,25 in‘Zhaohe Zhirong’and 31 in‘Xinyinv’.The volatile components and relative contents had greater differences among the five C.sasanqua cultivars,but the main characteristic volatile components of them were all acetophenone,cis-linaloloxide and linalool,and the main component types were alcohols,aldehydes and ketones.There were 21 components identified in‘Fushi Zhifeng’with formal double.The main characteristic volatile components of‘Fushi Zhifeng’were cis-linaloloxide,eugenol,cyclohexanone andtetradecane,and the main component types were alcohols,then alkanes.Analysis of volatile components showed obvious differences.These indicate that there are obvious differences of volatile components kinds and their relative contents of different C.sasanqua cultivars;Petals and stamens are the main flower parts of volatile components releasing.
