Abstract: In order to clarify the influences of different processing methods on the quality of Forsythia suspensa, this paper took suncure as control to study the effects of boiling-drying, steaming-drying, boiling-drying and integrated processing methods on the water content, total ash content, alcohol-soluble extractive, forsythin and forsythiaside A content. The results showed that there were no significant differences in water content and total ash content among the control group. The contents of alcohol-soluble extractive, forsythin and forsythiaside A in the integrated machine processing of Forsythia suspensa were significantly higher than that in other processing methods. Under the boiling-drying, steaming-drying and boiling-drying methods, the contents of alcohol-soluble extractive and forsythiaside A in Forsythia suspensa were significantly higher than that in the control group. Different processing methods had different influences on the quality of Forsythia suspensa. Within the scope of all indexes specified in Chinese pharmacopoeia, the quality of Forsythia suspensa processed by integrated machine was the best, followed by boiling-drying, steaming-drying and boiling-drying, and the effect of suncured was the worst.
