OBJECTIVE
To analyze the chemical components of the volatile oil in processed pieces of Eriobotrya japonica by GC-MS.
METHODS
The volatile oil was obtained by steam distillation. The amount of the components from the volatile oil were determinated by area normalization method. The separated components were identified by GC-MS.
RESULTS
The components of volatile oil in pre and post processed pieces of Eriobotrya japonica were different.
CONCLUSION
The methods is reliable, stable and has good repeatability. It will provide the certain scientific methods for further evaluation quality of Eriobotrya japonica.
目的
采用气相色谱-质谱联用（GC-MS）法分析加工后枇杷叶的挥发油化学成分。
方法
采用水蒸气蒸馏法提取挥发油，用面积归一化法测定挥发油中各成分的含量，通过GC-MS对分离出的成分进行鉴定。
结果
加工前后枇杷叶挥发油的成分有所不同。
结论
该方法可靠、稳定，重复性好，将为进一步评价枇杷叶质量提供一定的科学方法。
