摘要
大麦虫是一种高含油的新型资源昆虫。利用高效液相色谱法测定了大麦虫幼虫体内维生素E的含量,并对其随日龄、体重、体长的变化趋势进行了分析。结果表明:大麦虫幼虫含有丰富的α-维生素E和少量的δ、β、γ-维生素E,α-维生素E的变幅在168.64～264.57 mg/kg之间。在45～87日龄期间,大麦虫幼虫的日龄、体重、体长三者之间有极显著的线性相关(R2≥0.964,P<0.01)。α-维生素E含量与这三项指标有极显著的二项式曲线相关,其与体长相关性最高(R2=0.640,P<0.01),当体长达5.1 cm时,幼虫体内α-维生素E含量最高,是生产高维生素E产品结束养殖的最佳时间。
Zophobsmorio L. is a new kind of resource based insect with high oil content. In this study, the content of vitamin E in Zophobsmorio L. larvae was determined by HPLC and the varied trends of vitamin E in larvae according to age, body weight and body length were analyzed. The results indicated that the larvae contains rich α vitamin E and a small amount of δ、β、γ vitamin E, the content of α vitamin E ranged from 168.64 mg/kg to 264.57 mg/kg. At the period of 45 - 87 days of age, there were significant linear correlations either between age and body weight, or age and body length, all the square of correlation coefficients were more than 0.964 （P〈0.01）. The relationship among vitamin E of larvae and these three indexes significantly met the binomial curve （P〈0.01） , the maximum correlation existed between vitamin E and body length, the square of correlation coefficient was up to 0.640 （P〈0. 01 ）. The larvae could have the most α vitamin E content when the body length reached 5.1cm. So it was the best time to end the farming and process the larvae into production with high vitamin E content.
