Comparison of characteristic chromatogram and the contents of multiple indicator components of Morus alba decoction powder and decoction at different decoction time
To compare characteristic chromatogram and the contents of multiple indicator components of
Morus alba
decoction powder and decoction at different decoction time, and to provide experimental basis for the development of
M. alba
decoction.
METHODS
2
Taking decoction powder and decoction at different decoction time as subject, HPLC characteristic chromatogram of 2 kinds of samples were established with
Similarity Evaluation Software System of TCM Chromatographic Fingerprint
(2012 version), and similarity evaluation was performed. The contents of mulberroside A, geniposide, berberine, baicalin, quercetin and luteolin in decoction powder and decoction were determined by HPLC. The contents of each indicator component and the change of total content were as the evaluation indexes to compare the difference between the two substances during decoction.
RESULTS
2
The similarities of characteristic chromatogram of the two substances ranged from 0.943 to 1.000 and 0.975 to 0.998 at different decoction time, respectively. Six indicator components of the decoction powder dissolved faster and had higher contents. The contents of each indicator component in the decoction powder when decocting at 20 minutes was 1.1-1.5 times of the decoction when decocting at 50 min, and the total content in the decoction powder was 1.2 times of the decoction.
CONCLUSIONS
2
Compared with decoction,
M. alba
decoction powder has the advantages of shortening the decoction time and saving traditional Chinese medicine resources. The results of this study lay a research foundation for “Zungu” to develop its preparation.
