摘 要 ：采用顶空固相微萃取法（HS-SPME）提取了山茶品种‘克瑞墨大牡丹’不同花器官自然挥发的花香挥发油，并用气相色谱—质谱联用仪（GC-MS）分析了花香成分。分别从整花、花瓣、雄蕊中检测到了89、80、21种化合物。花香成分主要由萜类、芳香族化合物、脂肪族化合物等组成，其中以单萜中的芳樟醇相对含量最高，以下依次为顺式氧化芳樟醇、水杨酸甲酯、十四烷等。花瓣和雄蕊中花香成分有较大差别，芳樟醇在花瓣和雄蕊中均占首位，相对含量分别为15.12%和63.97%，雄蕊缺乏烷烃和芳香烃。同一朵花所有花瓣的花香绝对挥发量是所有雄蕊的3倍以上，但质量相同时雄蕊的挥发量却明显高于花瓣，表明花瓣和雄蕊对‘克瑞墨大牡丹’的花香具有同样重要的贡献。

Abstract:The volatile oils from different organs of Camellia ‘Kramer’s supreme’ flowers were extracted by HS-SPME and analyzed by GC-MS. Eighty-nine, eighty and twenty-one kinds of compounds were detected from the integral flower, petals and stamens, respectively. The aroma components were consisted of monoterpenes, sesquiterpenes, benzene compounds, alkanes, alcohols, straight chain olefins, aldehydes, ketones. The relative content of linalool is the highest in the compounds list, followed by cis-linaloloxide, methyl salicylate, tetradecane, etc. A significant difference exited between petals and stamens. The relative contents of linalool in petals and stamens were 15.12% and 63.97%. Alkanes and aromatic hydrocarbons were rare in stamens. The absolute amount of aroma components from all petals was three times over to that from all stamens in a same full flower, but the results were converse when comparing the weight of two sample. It indicated that petals and stamens had the same contribution to the fragrance of ‘Kramer’s supreme’.
