WU Ya-nan, ZHANG Gui-jun, LIU Liang, et al. Influence of Single Factor Compatible Dose on Active Components in Dahuang Gancao Tang[J]. Chinese journal of experimental traditional medical formulae, 2016, 22(16): 84-90. DOI: 10.13422/j.cnki.syfjx.2016160084.
Objective: To investigate the influence of dose change of Rhei Radix et Rhizoma and Glycyrrhizae Radix et Rhizoma on active components alignment in Dahuang Gancao Tang by using single factor analysis
to provide scientific basis for clinical rational use of this prescription and establishing the quality standard of traditional Chinese medicine. Method: HPLC-DAD was employed to determine the content of aloeemodin-rhein-glycyrrhizic acid-emodin-chrysophanol-physcion (λ=254 nm)
liquiritin-liquiritigenin (λ=276 nm)
sennoside B-sennoside A-isoliquiritin-isoliquiritigenin (λ=360 nm) in Dahuang Gancao Tang with different compatibility of herbs. Result: When compatible dose of Glycyrrhizae Radix et Rhizoma or Rhei Radix et Rhizoma in Dahuang Gancao Tang increased
contents of active components in Rhei Radix et Rhizoma or Glycyrrhizae Radix et Rhizoma reduced without exception.When compatible dose of Rhei Radix et Rhizoma-Glycyrrhizae Radix et Rhizoma stayed 12 g/3 g
contents of liquiritin-isoliquiritin-liquiritigenin-isoliquiritigenin-glycyrrhizic acid were (1 258.03±35.52)
(115.26±7.88)
(246.09±4.02)
(15.41±0.20)
(1 823.44±23.44) μg·g-1;contents of sennoside B-sennoside A-aloeemodin-rhein-glycyrrhizic acid-emodin-chrysophano1-physcion were (124.51±0.60)
(189.91±7.04)
(214.03±6.08)
(1 110.60±24.36)
(193.83±0.95)
(133.21±3.28)
(51.26±1.00) μg·g-1. Conclusion: As compatible dose of Rhei Radix et Rhizoma and Glycyrrhizae Radix et Rhizoma dose changing
dissolution of active components alignment in Dahuang Gancao Tang is significantly different by comparing with classic compatibility
efficacy of Dahuang Gancao Tang changes with compatible dose.Changes of compatible dose of Rhei Radix et Rhizoma (Glycyrrhizae Radix et Rhizoma) have significant influence on active components alignment in Glycyrrhizae Radix et Rhizoma (Rhei Radix et Rhizoma)
itself and Dahuang Gancao Tang.Influence of dose of Glycyrrhizae Radix et Rhizoma on active components alignment in Dahuang Gancao Tang is stronger than that of Rhei Radix et Rhizoma.
