ZOU Jing, LI Lin, REN Qing-ling, et al. Comparison of Fingerprints and Index Components Contents of Jiawei Ermiao Traditional Decoction and Granules[J]. Chinese journal of experimental traditional medical formulae, 2018, 24(12): 14-20. DOI: 10.13422/j.cnki.syfjx.20181102.
Objective: To compare the contents of seven chemical constituents in Jiawei Ermiao granules and traditional decoction
and to establish their fingerprints and evaluate the consistency of material basis. Method: Based on the established analysis method of determination and fingerprint in previous experiments
the contents of phellodendrine
berberine hydrochloride
jatrorrhizine hydrochloride
(R
S)-goitrin
astilbin
hesperidin
atracylenolide Ⅲ in Jiawei Ermiao granules and traditional decoction were determined.Taking berberine hydrochloride as the reference peak
the similarity of the granules and traditional decoction was carried out by similarity evaluation system for chromatographic fingerprint of traditional Chinese medicine (2012 edition).The difference of relative peak area of the granules and decoction was analyzed by principal component analysis (PCA)
and the decoction was decocted with decomposed recipes
the influence of decomposed recipes on fingerprint of Jiawei Ermiao decoction from the qualitative evaluation. Result: The contents of astilbin
jatrorrhizine hydrochloride
atracylenolide Ⅲ in the granules and decoction had no significant difference
the contents of phellodendrine
berberine hydrochloride
hesperidin and (R
S)-goitrin in the granules was higher than those of the traditional decoction.Twenty common peaks were indicated in the granules and 19 common peaks were indicated in the traditional decoction.There were no significant changes in the overall material basis between the granules and decoction.PCA results showed that the relative peak area of the traditional decoction was significantly different from that of the granules.There was no new compound in HPLC fingerprints of decoction with decomposed recipes. Conclusion: The established fingerprint reflects the overall material basis of Jiawei Ermiao granules and traditional decoction
the material basis of the granules and decoction is basically the same.The contents of these seven components combined with the fingerprints can reflect the intrinsic quality of the granules and traditional decoction
and provide reference for their clinical application.
