Object To examine if Leonurus artemisia (Lour ) S Y Hu (Labiatae) contains ferulic acid Methods The samples were extracted by different solvents and the extracts examined by TLC and HPLC Results Ferulic acid was detectable in the extracts of L artemisia Conclusion L artemisia possibly contains free ferulic acid The use of 5% Na 2CO 3 as the extractant instead of methanol, as described in Chinese Pharmacopoeia seemed to be more simple, highly stable and with good reproducibility
