摘要:

为合理利用桑椹中的白藜芦醇,以不同品种桑椹为原材料,测定不同的物候期和贮藏条件下桑椹中白藜芦醇的含量,分析其变化规律。不同品种成熟的桑椹中,‘中椹1号'中白藜芦醇含量最高,为0.3540 mg/g;同一品种桑椹中白藜芦醇含量随发育时期的推迟而不断减少,桑椹发育初期白藜芦醇含量最高。自发气调、减压、紫外照射、壳聚糖涂膜、水杨酸涂膜、1-MCP熏蒸、茉莉酸甲酯熏蒸等贮藏方式可以有效延长桑椹的贮藏时间,‘中椹1号'和‘白玉王'2个品种均可以延长8天,茉莉酸甲酯熏蒸、壳聚糖涂膜、减压贮藏和自发气调等贮藏条件可以有效保持白藜芦醇的含量。同一发育时期内不同品种、不同发育时期同一品种的桑椹中白藜芦醇含量存在差异。

Abstract:

To utilize resveratrol in mulberry, different varieties of mulberry were used as raw materials to determine the content of resveratrol in different phenological periods and storage conditions. The change rules were analyzed. The results showed that among the mature varieties, the highest content of resveratrol was 0.3540 mg/g in ‘Zhongshen 1', the content of resveratrol decreased with the development of mulberry, and the highest content was in the early stage of mulberry development. Storage methods, such as spontaneous air conditioning, reduced pressure storage, UV irradiation, chitosan coating, salicylic acid coating, 1-MCP fumigation, methyl jasmonate fumigation and etc., could effectively prolong the storage time of mulberry. The storage time of two varieties of ‘Zhongshen 1' and ‘Baiyuwang' could be extended for 8 days. The storage conditions, such as methyl jasmonate fumigation, chitosan coating, reduced pressure storage and spontaneous air conditioning, could effectively maintain the content of resveratrol. There were differences of the contents of resveratrol not only among different varieties, but also among different development periods of the same variety.

Key words: mulberry, resveratrol, phenological period, storage method, storage time
