Objective: To provide basis for utilization and development of Rhei Radix et Rhizoma through comparing its quality from different areas in Henan. Method: Rhapontin was checked
qualitative identification was determined by TLC
HPLC was employed to determine the content of free anthraquinones with mobile phase of methanol -0.1% phosphoric acid (85:15) and detection wavelength at 254 nm. Result: In 9 batches of samples
4 batches of Rhei Radix et Rhizoma contained rhapontin
it was identified as Rheum franzenbachii;5 batches did not contain rhapontin
the content of free anthraquinones all exceed 1.5% and conformed to rules in the 2010 edition of Chinese Pharmacopoeia
the content of free anthraquinones (4.65%) was higher in samples from Lushan county
followed by samples from Song county with 4.38%
These two kinds of samples were from R.officinale and R. palmatum
respectively. Conclusion: R. officinale and R. palmatum from different areas in Henan are all consistent with rules in the 2010 edition of Chinese Pharmacopoeia
it is worthy of exploitation and utilization.R. franzenbachii cannot be applied in medicinal materials as Rhei Radix et Rhizoma.
