Abstract:
Objective To establish the fingerprints for characterization of the chemical components of maidong(root of Ophiopogon japonicus) in two main cultivate regions of China,Sichuan(Chuanmaidong) and Zhejiang(Hangmaidong).Methods An HPLC-UV analytical methods was applied to detect 70% ethanol extracts of 20 samples from Sichuan and Zhejiang province,a "Fingerprint similarity evaluating system for TCM" issued by Pharmacopoeia Committee of P.R.China was used to evaluate the similarities all of the samples.Results The fingerprints revealed that the similarities were higher than 0.95 between samples from the same cultivate region,and were lower than 0.80 between samples from different regions of above two.Conclusion The fingerprints of Chuanmaidong and Hangmaidong were provided with high difference,and the difference can be taken as a most important proof for distinguishing the material medica of Chuanmaidong and Hangmaidong,but also in patent medicine of TCM.
