[Spectrum-effect relationships on enriching blood activities of fresh and dry roots of Angelica sinensis].

Ultra performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry(LC-MS) was used to establish the chromatography fingerprint for fresh(FRAS) and dry(RAS) roots of Angelica sinensis from 10 different places. The rat model of blood deficiency was established by acetyl-phenyl-hydrazine(APH) and cyclophosphamide(CTX). Then grey relational analysis(GRA) and partial least squares regression(PLS) were used to investigate the spectrum-effect relationship between the relative contents and the data of enriching blood pharmacodynamics efficacy.

[Spectrum-effect relationships on enriching blood activities of aerial parts of Angelica sinenis].

Ultraperformance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was used to establish the chromatography fingerprint for aerial parts of Angelica sinenis(AAS) from 10 different places. Acetyl-phenyl-hydrazine(APH) was used to duplicate the mouse model of blood deficiency. Then partial least squares regression was used to investigate the spectrum-effect relationship between the relative contents and the data of enriching blood pharmacodynamics efficacy.
