摘　　要：为进一步合理开发利用油樟资源,采用系统预试和专项预试相结合的方法分析脱油油樟叶的化学成分,并采用NaNO2-Al(NO3)3-NaOH比色法测定其总黄酮含量。结果表明:脱油油樟叶中含有有机酸、酚、鞣质、黄酮、挥发油或油脂、氨基酸、多肽、蛋白质、还原糖、多糖、甙类、甾体、三萜、内酯、香豆素及其甙类化学成分,其中总黄酮含量为21.2mg·g-1。可见,脱油油樟叶含有多种类型化学成分,其总黄酮含量较高。In order to further legitimately develop and utilize Cinnamomum longepaniculatum resources, it was investigated by the methods of system and special pretesting. The contents of total flavonoids in de-oiled leaves were measured by colorimetric method with sodium nitrite-aluminum nitrate-sodium hydroxide. The results showed that de-oiled leaves contained organic acid, phenol, tannin, flavone, volatile oil or grease, amino acid, pol- ypeptide, protein, reducing sugar, polysaccharide, glycoside, steroid, triterpene, lactone, coumarin and its glyco- side. The content of total flavonoids of de-oiled leaves was 21.2 mg·g^-1. The de-oiled leaves of C. longepanicu- latum contained many kinds of chemical constituent and sufficient total flavonoids.
