杜仲花粉营养成分的研究

为了给杜仲花粉开发利用提供科学依据，采用紫外可见分光光度计、氨基酸分析仪、高效液相色谱仪、原子吸收分光光度计等对杜仲花粉中蛋白质、氨基酸、糖、粗脂肪、维生素、总黄酮及矿质元素进行了测定。结果表明杜仲花粉含蛋白质28.27 %、氨基酸总量180.10 g·kg-1、人体必须的氨基酸60.97 g·kg-1、还原糖6.70%、蔗糖1.90%、粗脂肪2.50%、VA1153.10 μg·kg-1、VE 22.46 mg·kg-1、总黄酮3.36%，并含有丰富的矿质元素。杜仲花粉营养成分丰富，具有较高的开发利用价值。西北林学院学报22卷第6期马仁萍等杜仲花粉营养成分的研究

Nutritional Components of Eucommia ulmoides Pollen

Nutritional components of Eucommia ulmoides pollen were measured,such as crude protein,amino acids, sugar,crude fat,vitamins,flavonoids and mineral elements. The results showed that the contents of crude protein were 28.27%,tatal amino acids 180.1 g·kg-1,incruding 60.77g·kg-1 essential amino acids,reducing sugar 6.70%,sucrose 1.90%,and crude fat 2.50%.The pollen was also rich in vitamins,bioactive constituent,and mineral elements.The contents of VA1 were 153.10 μg·kg-1,VE 22.46 mg·kg-1,and total flavonoids 3.36%. Indicating that E. ulmoides pollen is worth to be explored and utilized due to it's allround and abundant nutritional ingredients.
