产地加工方法对青翘中连翘苷、连翘酯苷A的影响

目的:利用不同的评价指标,探讨青翘药材产地加工方法,选择最佳产地加工工艺.方法:采用L9(34)正交试验法和单因素试验法对青翘进行产地加工,采用HPLC测定不同青翘炮制品中连翘苷、连翘酯苷A的含量.结果:蒸制青翘中连翘苷、连翘酯苷A的质量分数分别为1.33～ 3.05,9.71～44.82mg· g-1;煮制青翘中连翘苷、连翘酯苷A的质量分数分别为4.63 ～5.46,40.20 ～64.84 mg·g-1.结论:以连翘苷、连翘酯苷A为评价指标,煮法优于蒸法.青翘采收后当采用4倍量的水,煮制10 min,有利于青翘中连翘苷、连翘酯苷A的保存和稳定.

Effect of habitat processing method on phillyrin and forsythiaside A of Forsythiae Fructus

Objective: To investigate the habitat processing method of Forsythiae Fructus based on the different indexes, and to choose the best habitat producing process. Method: The habitat producing process was researched by the L₉(3⁴)orthogonal and the single factor test. The contents of phillyrin and forsythiaside A were determined by HPLC. Result: The contents of phillyrin and forsythiaside A from Forsythiae Fructus processed by evaporating were 1.33-3.05, and 9.71-44.82 mg·g^-1, respectively. The contents of phillyrin and forsythiaside A from Forsythiae Fructus processed by cooking were 4.63-5.46 mg·g^-1, and 40.20-64.84 mg·g^-1, respectively. Conclusion: With phillyrin and forsythiaside A as evaluation indexes, cooking method is superior to evaporate method while it is superior to dry method. It is conductive to the preservation and stability of phillyrin and forsythiaside A that add 4 times water of material volum and boil 10 min.
