Abstract:The appearance quality，nutritive components and volatile oil composition of three kinds of Rosa rox－ burghii Tratt in Anshun City were determined and analyzed by conventional means to provide a reference for de－ velopment and utilization of Rosa roxburghii Tratt in Anshun City. The experimental results showed that： there was a big difference between the physical properties of three kinds of Rosa roxburghii Tratt； the moisture content was as follows： sample 2＞sample 3＞sample 1； the fiber content was as follows： sample 3＞sample 1＞sample 2； the content of total acid， total sugar，VC and β-carotene was as follows： sample 1＞sample 3＞sample 2； the tan－ nin content was as follows： sample 3＞sample 2＞sample 1； the volatile oil components was as follows：simple 1＞＞sample 2＞sample 3；sample 2 had the highest K content，sample 1 had the highest Ca，Mg，Mn content，sam－ ple 3 had the highest Fe，Zn，Cu content. The volatile oil of sample 1， sample 2 and sample 3 were composed of 29， 28 and 14 species， the composition of species， content and proportion of volatile oil of three kinds of Rosa roxburghii Tratt were significant differences.
