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.

摘要： 为明确不同加工方式对连翘药材品质的影响，以生晒法为对照，研究了煮-晒、蒸-晒、煮-烘和一体化机器加工方式对连翘水分、总灰分、醇溶性浸出物、连翘苷和连翘酯苷A含量的影响。结果表明：不同加工方式下，连翘药材水分和总灰分含量与对照差异不显著；一体化机器加工的连翘药材中醇溶性浸出物、连翘苷和连翘酯苷A含量显著高于其他加工方式；煮-晒、蒸-晒和煮-烘加工方式下，连翘药材中醇溶性浸出物和连翘酯苷A含量均显著高于对照。不同加工方式对连翘药材品质影响差异较大，各指标都达到《中国药典》规定范围内，一体化机器加工的连翘药材品质最优，煮-晒、蒸-晒和煮-烘方式次之，生晒方式效果最差。
