- Abstract
The purpose of this experiment was to optimize the process of probiotics solid-state fermentation on stems and leaves of Angelica pubescens Radix, and to increase the content of osthole in stems and leaves of Angelica pubescens Radix. In this experiment, Bacillus amyloliquefaciens strain SSYB was used to ferment the stems and leaves of Angelica pubescens Radix, and on the basis of single factor test, the solid-state fermentation process was optimized by orthogonal experimental design, and the content of osthole in stems and leaves of Angelica pubescens Radix before and after the fermentation process was determined by high performance liquid chromatography. The results showed that the optimized fermentation process of stems and leaves of Angelica pubescens Radix was fermentation time of 72 h, fermentation temperature of 37 ℃, inoculation amount of 5%, and water content 65%. Under these conditions, the content of osthole in stems and leaves of Angelica pubescens Radix was 1.81 mg/g, which was significantly higher than that before fermentation by 45.97% (P<0.01). The results show that the content of osthole in stems and leaves of Angelica pubescens Radix is increased by optimizing the solid-state fermentation process of Bacillus amyloliquefaciens SSYB.
