Quality Control of Danggui Buxue Tang, a Traditional Chinese Medicine Decoction, by -NMR Metabolic Profiling
Figure 4
Quantification of identified metabolites in DBT and other herbal extracts. The peaks associated with identified metabolites in all of the -NMR spectra were integrated to yield the concentrations in the extracts. Although glutamate was also observed to differentiate DBT samples from others, as in Figure 2(b), statistical analysis showed that the differences between DBT and AR groups were not significant. The values are expressed as means ± SEM (, , ), by Student’s t-test. Abbreviations: AR: Astragali Radix; ASR: Angelica Sinensis Radix; DBT: Danggui Buxue Tang; AR + ASR: Astragali Radix + Angelica Sinensis Radix.
