胡颓子属5种植物果实主要类胡萝卜素成分及含量

利用高效液相色谱法对华东地区常见的胡颓子属(Elaeagnus)4种生态型的胡颓子(E.pungens)、2个变种的大叶胡颓子(E.macrophylla)、蔓胡颓子(E.glabra)、银果胡颓子(E.magna)和佘山胡颓子(E.argyi)9个样品成熟果实所含主要类胡萝卜素成分及含量进行了检测。结果表明,5种胡颓子属植物成熟果实中的主要类胡萝卜素成分为番茄红素,且在不同种间含量差异显著,含量最高的是浙江嵊州的胡颓子,其值为(259.89±26.22)μg·g~(-1)FW,最低的是佘山胡颓子,其含量为(91.19±7.74)μg·g~(-1)FW;其中4种生态型的胡颓子的番茄红素含量都较高。研究表明这5种胡颓子属植物果实富含番茄红素,是一类珍贵的天然番茄红素资源,具有较大的市场开发应用价值。研究结果为揭示果实高积累番茄红素的机理提供了理想的研究材料。

Determination of Carotenoids in Fruit of Five Elaeagnus spp. Genotypes by High Performance Liquid Chromatography

This study analyzed carotenoid types and content in the fruit of several Elaeagnus spp. including 4 ecotypes of E. pungens, 2 varieties of E. macrophylla, E. glabra, E. magna and E. argyi, by high performance liquid chromatography (HPLC). Lycopene is the major carotenoid in the fleshy pulp, and their content differed between the 5 genotypes. The greatest mean lycopene content was up to (259.89±26.22) µg·g^-1 fresh weight (FW) in E. pungens from Shengzhou of Zhejiang and the lowest was (91.19±7.74) µg·g^-1 FW in E. argyi. The lycopene content was high in all 4 ecotypes of E. pungens. The flesh of the 5 Elaeagnus spp. showed abundant lycopene, for beneficial fruit resources with important development and application value. These genotypes are also ideal research material for studying the mechanism of high accumulation of lycopene in fruit.
