采用紫外分光光度快速测定法、Folin-酚法、静态顶空和气相色谱-质谱联用技术,分别对上海植物园20世纪90年代木瓜属Chaenomeles×superba和Chaenomeles speciosa杂交选育的11个果用新品系果实进行了分析.结果表明,维生素C含量在25.27～168.69 mg·100 mL-1,酚类物质含量在185.49～346.03 mg·100 mL-1;新品系23-0183的维生素C含量最高,达168.69 mg·100 mL-1;4-067的酚类物质含量最高,达346.03 mg·100 mL-1.果实具浓香的新品系4-067共鉴定出25种主要挥发性成分,主要有:辛酸丙酯、乙酸-2-甲基-1-丁醇酯、己酸丙酯、异丁酸叶醇酯、己酸丁酯、乙酸叶醇酯、2-甲基丁酸己酯、辛酸正丁酯、己酸异戊酯、辛酸异丁酯、a-紫罗兰酮、己酸己酯、Z-3-己烯基-2甲基丁酸酯、2-甲基丁酸己酯和E-4-葵烯酸乙酯.%:Chaenomeles is one of the important germplasm for medicine, food and landscaping, Shanghai Botanical Garden started a breeding program among Chaenomeles X superha and Chaenomeles speciosa from 1990s) a series of new strains which are suitable for food industry, flavor or medicine had been selected. In this paper, knowledge of vitamin C, phenolic compounds and aroma components in fruits of Chaenomeles new strains were studied by UV Spectrophotometry , Folin-phenol method, SPME and GC-MS separately, vitamin C and phenolic compounds of 11 strains were 25. 27~168. 69 mg · 100 mL-1 and 185. 49~346. 03 mg · 100 mL-1 respectively. New strain of 23-0183 had the highest content of vitamin C, while the strain 4-067 had the highest content of phenolic compounds. This is of great interest for its applications in food industry as acidifying agent with antioxidant properties. Twenty five main volatiles were identified from the fruit of the strain 4-067 with strong fragrance. The main components were as follows- propyl octano-ate; 1-butanol 2-methyl- acetate, hexanoic acid propyl ester, cis-3-hexenyl isobutyrate, hexanoic acid butyl ester, (Z)- 3-hexen-l-ol acetate, hexyl 2-methylbutanoate, butyl caprylate, isopentyl hexanoate, iso bu-tylcaprylate, alpha.-ionone, hexanoic acid hexyl ester, Z-3-hexenyl 2-methylbutanoate, hexyl 2-methylbutanoate and ethyl E-4-decenoate.
