Background: Leonurine is a the aerial part of Leonurus japonicus Houttuyn, which has been used as a traditional medicines and is registered in the Korean Pharmacopoeia.
Methods and Results: In the present study we performed a heavy metals and thin layer chromatography and measured loss on drying, as well as the contents of total ash, acid-insoluble ash, ethanol soluble compounds, and leonurine, using 15 domestically collected L. japonicus samples. The methods were performed according to the ¡®crude drugs test of the general test, processes and apparatus¡¯, published by MFDS, Korea (2014). The purity test (heavy metals) indicated that levels of Pb and Hg were 0.35 - 3.64, and 0.001 ppm, respectively, whereas the levels of As and Cd were undetectable, and stachydrine was identified by thin layer chromatography (Rf : 0.15). We found that 5.93 - 10.62% (average: 8.58 ¡¾ 1.8%) of the sample mass was lost during drying, and the contents of total ash, acid-insoluble ash, ethanol soluble compounds, and leonurine were 7.87 - 10.84% (average: 9.62 ¡¾ 0.82%), 0.99 - 1.76% (average: 1.38 ¡¾ 0.24%), 16.70 - 23.11% (average: 19.49 ¡¾ 2.14%) and 0.04 - 0.17% (average: 0.11 ¡¾ 0.04%) respectively. In addition, HPLC profiling detected leonurine (5.94 min), rutin (16.43 min) and myricetin (26.78 min).
Conclusions: We hope that this the rusult of the present study will contribute to the standardization and quality control of Korean herbal medicines.
