摘 要 ：研究麻黄炮制前后挥发油含量及其油中化学成分的变化。结果表明:低沸点物质增多,含量也增高;高沸点物质减少,含量也降低。以炒黄麻黄变化尤为明显。

Abstract:This paper deals with the changes in contents and chemical composition in the volatile oil of Ephedra sinica before and after processing. The results indicate that after processing, the more the substances of low boiling point, the higher their contents and vice versa. The changes are particularly obvious in yellow-fried Ephedra sinica.
