[Studies on chemical constituents and volatile oil of Xiaochengqi decoction].
OBJECTIVE
To study the chemical constituents and volatile oil of Xiaochengqi decoction.


METHODS
The constituents in decoction were separated by means of column chromatography and their structures were identified by spectral data and compared with literature data. As well as the volatile oil of Xiaochengqi Fang were analyzed and identified by GC-MS.


RESULTS
Eleven compounds were isolated and identified as chrysophanol (1), physcion (2), magnolol (3), beta-sitosterol (4), sitosterol trans-cinnamic acid (5), emodin (6), aloe emodin (7), rhein (8), gallic acid (9), chrysophanol-8-O-beta-D-glucopyranoside (10), aurantiamarin (11). The volatile oils extracted with steam distillation from Xiaochengqi were identified 67 components, and the main components are including.


CONCLUSIONS
All of the eleven compounds were isolated from Xiaochengqi decoction for the first time and the study on their activities in Chinese prescription is being carried out. D-limonene (42.61%), p-cymene (16.43%), and 8-terpinene (14.46%).
