Objective:
To establish a HPLC-ELSD fingerprint of Marsdenia tenacissima from different habitats, in order to provide a reliable method for scientific assessment and effective quality control.
Method:
HPLC-ELSD was adopted to determine 25 baches of M. tenacissima herbs from different habitats. Traditional Chinese medicine chromatographic fingerprint similarity software assessment system 2004 developed by China Pharmacopoeia Committee was adopted to establish a common mode chart and assess chromatographic similarity based on the degree of correlation.
Result:
The common mode for M. tenacissima herb C21 steroidal fingerprint was established, including 11 common characteristic peaks. Among them, 10 were identified. According to the assessment on the similarity of 25 batches of samples, 80% of them showed a similarity of over 0.80 in steroidal HPLC-ELSD fingerprint.
Conclusion:
The method can be used to assess the quality of M. tenacissima.
