Abstract:
OBJECTIVE: To compare content of anthraquinones in the decoction and maceration of Rheum officinale.METHODS: Aloe emodin and four other components in R.officinale were taken as analysis objects.HPLC was used to determine the content of nomadic anthraquinone,conjugated anthraquinone and total anthraquinone in R.officinale during decoction process and maceration process.RESULTS: The linear range of aloe emodin,rhein,emodin and chrysophanol were 0.03～0.64?g and the linear range of physcion were 0.01～0.34 ?g.The concentration of total anthraquinones in decoction process was much higher than in maceration process.The change of dissolution of nomadic anthraquinones in two processes kept stable with process time.The content of conjugated anthraquinones in two processes was all decreased to some extent.CONCLUSION: The concentrations of anthraquinones in R.officinale are influenced by decoction process and maceration process.
