[Objective]To provide references for the establishment of quality standard of RADIX ET RHIZOMA HERACLEI. [Methods]Pharmacognosy,characters and microscopic identification methods were adopted. With reference substances of RADIX ET RHIZOMA HERACLEI as the control,TLC identification was carried out. According to the methods in Chinese Pharmacopoeia( edition 2010),the moisture content,total ash content and acid-insoluble ash content were detected in ten batches of RADIX ET RHIZOMA HERACLEI. [Results]Characters of pharmacognostic identification of RADIX ET RHIZOMA HERACLEI were descibed. RADIX ET RHIZOMA HERACLEI and its reference substances had the same color of fluorescent spots. The moisture,total ash,acid-insoluble ash contents should be less than 12. 0%,8. 0% and 2. 0%,respectively; while the extracts content should be more than 23. 0%. [Conclusions]TLC identification had strong specificity; the research results provided references for the identification,development and utilization of RADIX ET RHIZOMA HERACLEI,as well as the quality standard establishment of RADIX ET RHIZOMA HERACLEI.
