产地和树叶类型与厚朴质量关系的研究

Study on the Relationship between Provenance, Leaf Type and Quality in Magnolia officinalis

研究结果表明,不同树叶类型的厚朴有效成份含量存在极显著的差异,是决定厚朴质量的关键。不同产地厚朴质量虽有显著差异,但主要受栽培品种和类型的影响。

An analysis of effective ingredients in 20 to 29 year old Magnolia officinalis of three different leaf types coming from various sources shows that the content of phenols differ extremely significantly in various leaf types which are a key to determination of quality of Magnolia officinatis also varies significantly among different sources which only have a significant effect on the content of magnolol. Varieties and types cultivated in different places are responsible for the variation in content of magnolol. The conclusions obtained from this study coincide with the traditional insight into quality of Magnolia officinalis
