Objective:To investigate the contents of anthraquinones in the root of Rumex , and to evaluate its pharmaceutical value. Methods: HPLC method was applied to measure the contents of anthraquinones in the root of 5 kinds of Rumex and 3 intraspecies of R. japonicus. Results: The contents of emodin, chrysophanol, physcion ranged from 0.051% 0.303%, 0.095% 0.320%, 0.025% 0.142% in the root of 5 kinds of Rumex , and ranged from 0.051% 0.125%, 0.127% 0.193%, 0.049% 0.096% respectively in 3 intraspecies of R. japonicus. Conclusion: Both R.patientia and R.japonicus can be employed as ‘Yangti’ clinically as antibiotics for their anthraquinone contents are almost the same. Contents of anthraquinone in R. japonicus from different place and under different enviroment are different. Contents of 3 anthraquinones in R.japonicus (Nanjing) are the highest, and those in R.madaio and R.acetosa are next to them, but less in R.dentatus . [
