摘要: 利用顶空固相微萃取结合气相色谱-质谱联用技术对盛花期的香花秋海棠(Begonia handelii)雄花及其变种铺地秋海棠(B. handelii var. prostrata)雌花和红毛香花秋海棠(B. handelii var. rubropilosa)雄花的挥发性香气成分进行分析。结果表明,从铺地秋海棠花中鉴定出香气成分32 种,其中醇类物质含量最高,占总成分50.10,其次分别为碳氢类、醛类和酸类物质,分别占总成分25.39、13.87、4.34;从香花秋海棠花中鉴定出香气成分为21种,醛类物质含量最高,占总成分57.12,其次是醇类、碳氢类、杂环类物质,分别占总成分17.37、15.31、4.88;从红毛香花秋海棠花中鉴定出香气成分44 种,醇类物质含量最高,占总成分38.22,其次是碳氢类、醛类和醚类物质,分别占总成分34.36、16.83、6.91。铺地秋海棠和红毛香花秋海棠香气成分较接近,富含具有清香、甘甜气息的芳樟醇氧化物等物质;香花秋海棠花中醛类物质含量最高,具有淡焦甜香气。

Abstract: Using HS-SPME/GC-MS, the aroma components in the male flowers of Begonia handelii and two of its varieties, B. handelii var. prostrata (female flowers) and B. handelii var. rubropilosa (male flowers) were analyzed. The results showed that 32 kinds of aroma components identified were the flowers of B. handelii var. prostrata, with alcohols accounting for 50.10 of the total composition, and hydrocarbons, aldehydes, acids accounting for 25.39, 13.87, 4.34 respectively. Twenty-one kinds of aroma components were identified the flowers of B. handelii, with aldehydes accounting for 57.12 of the total composition, and alcohols, hydrocarbons, heterocyclic substances accounting for 17.37, 15.31, 4.88 respectively. Forty-four kinds of aroma components were identified the flowers of B. handelii var. rubropilosa, with alcohols accounting for 38.22 of the total composition, and hydrocarbons, aldehydes and ethers accounting for 34.36, 16.83 and 6.91 respectively.comparison and analyses, the aroma components of B. handelii var. prostrata and B. handelii var. rubropilosa were relatively close, emitting the sweet, faint scents that characterized linalool oxides. The aroma components of B. handelii flowers had the highest content of aldehydes and the scent was similar to delicately sweet caramel.
