Abstract

The volatile oil was extracted from leaf of Cratoxylum formosum(Jack) Dyer subsp. pruniflorum (Kurz) Gogelin in Xishuangbanna of Yunnan Province by steam distillation and its constituents were analyzed by GC-MS technique. The results show that 84 peaks are separated from the volatile oil and 70 compounds are identified, which represents 96.91% of total content. Sesquiterpenoids are the major chemical constituents in the volatile oil, accounted for 86.01% of total content.The major compounds are caryophyllene(23.99%), α-cedrene(10.57%), curcumene(8.75%) and α-caryophyllene(8.57%), etc. The results provide basic data for comprehensive utilization of C. formosum  subsp. pruniflorum
