摘要: 采用顶空固相微萃取—气质联用技术分析了中国李(Prunus salicina)‘绥李3号’、樱桃李(P. cerasifera)‘红果樱桃李’及其种间杂种‘蜜思李’的果实香气成分。结果表明,3种果实香气物质组成及含量存在显著差异,‘蜜思李’、‘绥李3号’和‘红果樱桃李’分别检测出58、53和29种香气成分,且‘蜜思李’香气物质含量最高;‘绥李3号’主要香气物质是醛类,‘红果樱桃李’为醇类,‘蜜思李’为酯类;γ–十二内酯和γ–癸内酯是‘蜜思李’特有香气物质;根据香气成分的种类及含量,可将‘蜜思李’和‘红果樱桃李’分别划为“酯香型”李和“醇香型”李类型。

Abstract: Volatiles in fruits of three cultivars belonging to different plum species[‘Suili 3’(Prunus salicina),‘Hongguo Yingtaoli’(P. cerasifera)and‘Methley’(interspecific hybrid of the two previous species)] were evaluated by HS–SPME–GC–MS. Results showed that there were differences in both volatile compounds and their contents among cultivars. A total of 58,53 and 29 aromatic volatile compounds were detected in‘Methley’,‘Suili 3’and ‘Hongguo Yingtaoli’,respectively. Moreover,the highest content of volatiles were found in‘Methley’fruits. Aldehydes,alcohols and esters were the dominant volatiles in‘Suili 3’,‘Hongguo Yingtaoli’and‘Methley’,respectively. γ-dodecalactone and γ-decalactone were unique components to‘Methley’. According to volatile components,‘Methley’could be classified as an ester-type plum and’Hongguo Yingtaoli’as alcohol-type.
