【Abstract】 Objective: To investigate the contents of magnonol and honokiol in the leaf of Magnolia officinalis in different areas. Methods: TLC scanning method was used to determine both the contents. Results: The method is simple, rapid, accurate and sensitive. The average recovery and RSD of magnonol are 104.4% and 2.4% respectively. The average recovery and RSD of honokiol are 102.3% and 3.9%respectively. Conclusion: The average content of magnonol or honokiol in the leaf is about one quarter of that in the cortex. The leaf can be considered as a substitute of the cortex.更多还原
