Abstract:
Objective:To approach the determination method of 5-hydroxymethyl-furfural in Radix Rehmanniae,and to investigate influence of steam processing on catalpol and 5-hydroxymethyl-furfural. Methods:Catalpol and 5-hydroxymethyl-furfural from Radix Rehmanniae at different processing time was determined by high performance liquid chromatography. Results:In the steam processing,content of 5-hydroxymethyl-furfural increased with the increase of time in the beginning,when steamed to 52h,the levels began to decline; content of catalpol reduced with increase of the processing time. Conclusion:Content of catalpol and 5-hydroxymethyl-furfural changed signifi cantly in the steam processing.
