Identification of components, fingerprint and content determination of the effective parts of Dracocephalum moldavica
To provide a reference for comprehensive quality evaluation and control of the effective parts of
Dracocephalum moldavica
(EPDM).
METHODS
2
A total of 10 batches of EPDM were prepared, and chemical information of EPDM was collected by HPLC-Q-Exactive-MS. EPDM components were identified by literature search, database comparison and manual analysis. HPLC fingerprints of 10 batches of EPDM were established by using the
Similarity Evaluation System for Traditional Chinese Medicine Chromatographic Fingerprint
(2004 A edition); the similarity evaluation and common peak identification were carried out, and the contents of 5 index components were determined by HPLC.
RESULTS
2
A total of 11 compounds in EPDM were identified. The fingerprint similarities of EPDM samples from 10 batches were all above 0.96. Among 11 chromatographic peaks, 5 peaks were identified, such as luteolin-7-
glucuronide(DG), tilianin(TL) . The results of the quantitative ana
lysis showed that all above 5 components had good linearity (
R
2
≥0.999), and the average recoveries were in the range of 95.12%-98.37%. The contents of LG, APG, RA, DG, TL were 21.268 3-29.243 9, 6.365 4-7.771 7, 37.327 4-45.671 2, 17.169 9-21.985 9, 66.940 4-91.206 3 mg/g, respectively.
CONCLUSIONS
2
The established method of component identification, fingerprint and content determination is stable, feasible and reliable, which is suitable for the comprehensive quality evaluation and control of EPDM.
