To identify the endophyte strain E8 with high activity from Curcuma wenyujin and study its secondary metabolites.. The strain E8 was identified by morphological observation and ITS sequence analysis. Manifold chromatographic methods were used to separate and purify the chemical constituents of fermentation broth from strain E8, and their structures were identified by physiochemical properties and spectral data.. The strain E8 belongs to P. oxalicum. Four compounds were isolated from the fermentation broth of this strain and elucidated as chrysophanol, emodin, secalonic acid A and beta-sitosterol.. The endophyte P. oxalicum was isolated from medicinal plant Curcuma wenyujin for the first time. Four compounds were first isolated from endophytic fungus in C. wenyujin. Thus, microbial fermentation is a new access for these compounds production.

To study the chemical constituents and volatile oil of Xiaochengqi decoction.. 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.. 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.. 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%).
