Abstract:
This study was aimed to establish a method to determine the content of phenolic acids in the soil of cultivation base ofCoptis chinensis, in order to study the accumulation and decrease law of phenolic acids. The content of total phenolic acid was determined by ferric chloride-ferricyanatum calcium colorimetric method. Thecontent of ferulic acid in Coptis chinensis was determined by HPLC. The results showed that the contents of total phenolic acid and ferulic acid in the soil of cultivation base of Coptis chinensis were in the range from 0.545-0.026 mg·g-1 and 0.139 to 0.652 μg·g-1, respectively. It was concluded that the variation of phenolic acids in the soil of cultivation base ofCoptis chinensis was obvious. With the increase of growth age of Coptis chinensis, the contents of total phenolic acid and ferulic acid in the soil of cultivation base of Coptis chinensis were increased in the cultivation period. With the increase of fallow age, the contents of total phenolic acid and ferulic acid in the soil of cultivation base ofCoptis chinensis showed decrease tendency in the fallow period of Coptis chinensis. The variation tendency of phenolic acids contents in the soil of cultivation base ofCoptis chinensis can be referred to in the study of the continuous cropping obstacle of Coptis chinensis.
