摘　　要：对濒危植物长叶榧不同产地、不同质量大小的种子中可溶性糖、粗脂肪、总蛋白质、总黄酮、总绿原酸、总鞣质等6种化学成分的含量进行了测定与分析。结果表明:不同产地、不同质量大小的长叶榧种子中6种化学成分的含量均存在差异。不同产地长叶榧种子中可溶性糖、总黄酮的含量以浦江地区最高,粗脂肪、总绿原酸、总鞣质的含量以桐庐地区最高,总蛋白质的含量以富阳地区最高。桐庐地区不同质量大小的长叶榧种子中,除总绿原酸外,种子质量越大,可溶性糖、总黄酮、总鞣质的含量越高,但粗脂肪、总蛋白质的含量却越低。长叶榧种子可溶性糖的含量与粗脂肪的含量呈显著负相关。The contents of six chemical components, such as soluble carbohydrate, crude fat, total protein, total flavonoids, total chlorogenic acid and total tannin in the seeds of an endangered plant Torreya jackii with different producing area and different quality were determined and analyzed. The results showed as follows： the contents of six chemical compositions were different in the seeds of Torreya jackii with different producing area and different quality. In the seeds of Torreya jackii with different producing area, the contents of soluble carbohydrate and total flavonoids were highest in the Pujiang region, the contents of crude fat and total chlorogenic acid and total tannin were highest in the Tonglu region, the content of total protein was highest in the Fuyang region. In the seeds of Torreya jackii with different quality in the Tonglu region, the contents of soluble carbohydrate and total flavonoids and total tannin were higher and higher but the contents of crude fat and total protein were lower and lower while the quality of seed was larger and larger except total chlorogenic acid. There was significant negative correlation between the total content of soluble carbohydrate and the content of crude fat.
