文摘

To identify the coumarins constituents in Cnidium monnieri and classify ten samples into three groups and this helpful chemical information could be used for the further pharmacological and clinical study on C. monnieri.

Methods

Qualitative analysis of coumarins in C. monnieri was detected by UHPLC-ESI-Q-TOF/MS. Quadrupole TOF/MS in either full scan mode or extracted ion mode was used for the qualitative analysis of the constituents. Relative peak area of each component was used for the hierarchical cluster analysis.

Results

According to UHPLC-ESI-QTOF-MS data, chemical structures of 28 coumarins in the fruits of C. monnieri were identified, including 19 simple coumarins, seven linear coumarins, and two angular coumarins. Among these constituents, ten coumarins were firstly identified in C. monnieri. In addition, hierarchical cluster analysis suggested that C. monnieri from different regions could be classified into four groups, and this clustering was correlated to the distribution significantly, Xuzhou could be regarded as the genuine producing area.

Conclusion

UHPLC-ESI-Q-TOF-MS is a viable method for qualitative analysis and quality evaluation of coumarins from the fruit of C. monnieri. Coumarins in C. monnieri exists intra-species variance, which indicates significant meaning for the quality control and choice of famous region drug for C. monnieri in the clinic medication.
