Abstract:
OBJECTIVE:To establish the GC fingerpriont for Lingyang ganmao tablets.METHODS:The determination was performed on DB-5 ms capillary column.Flame ionization detector was adopted with temperature of 250 ℃ (temperature programming).The temperature of injector was 240 ℃.Carrier gas was nitrogen with flow rate of 1.0 mL/min;the sample size was 1 μL by split sampling with split ratio of 20 ∶ 1.Using peppermint ketone as reference,Similarity Evaluation Software for Chromatographic Fingerprint of Traditional Chinese Medicine (2012 edition) was used for the similarity analysis of 10 batches of Lingyang ganmao tablets.RESULTS:There were 14 common peaks in the batches of Lingyang ganmao tablets,similarity degrees were higher than 0.98.It was proved that the GC profiles and control fingerprint of 10 batches of samples had good consistency.CONCLUSIONS:The established fingerprint can provide reference for the identification and quality evaluation of Lingyang ganmao tablets.
