引进和杂交两类沙棘果实VE含量测定分析

Determination and Analysis of VE Contents in Introduced and Hybrid Seabuckthorn Fruits

摘要: 为了系统掌握引进沙棘和杂交沙棘果实的VE含量，“三北”地区的黑龙江、辽宁、甘肃、青海和新疆5地的沙棘果实于2017年和2018年采摘后，立即采用高效液相色谱法做了测定分析，结果表明：干全果VE含量平均值，引进沙棘为315.67 mg/100g，杂交沙棘为455.79 mg/100g，较引进沙棘高44%，两类间平均值有一定差距；引进沙棘、杂交沙棘干全果VE含量，均以辽宁最高，分别达398.99 mg/100g、565.02 mg/100g，为含量最低的青海的1.44和2.17倍；引进沙棘干果肉VE含量为87.04 mg/100g，较干籽含量27.20 mg/100g高出2.20倍，VE主要存在于沙棘果肉中。引进沙棘和杂交沙棘果实的生物活性成分很多，功能也多种多样，VE含量方面所做的一些测试分析，旨在为全面衡量沙棘果实营养成分、服务大众健康，以及确定合理育种方案等提供有关科学依据。

Abstract: In order to systematically master the VE content of introduced seabuckthorn and hybrid seabuckthorn fruits, the fruits from Heilongjiang, Liaoning, Gansu, Qinghai and Xinjiang in the “Three North” region were collected, measured and analyzed by high-performance liquid chromatography immediately after picking in 2017 and 2018. The results showed that the average VE content of dry whole fruits was 315.67 mg/100g for introduced seabuckthorn and 455.79 mg/100g for hybrid seabuckthorn, which was 44% higher than that of introduced seabuckthorn, and there was a certain gap between the two types. The content of VE in the dry whole fruit of introduced seabuckthorn and hybrid seabuckthorn was the highest in Liaoning, up to 398.99 mg/100g and 565.02 mg/100g respectively, which was 1.44 and 2.17 times higher than that in Qinghai. The VE content of introduced seabuckthorn dry pulp was 87.04 mg/100g, which was 2.20 times higher than that of dry seed 27.20 mg/100g, indicating that VE mainly existed in seabuckthorn pulp. The introduced seabuckthorn and hybrid seabuckthorn fruits had many bioactive components and diverse functions. Those tests and analysis on VE content were designed to provide a relevant scientific basis for comprehensively measuring the nutritional components of seabuckthorn fruits, serving public health, and determining reasonable breeding schemes.
