| Abstract: | OBJECTIVE: To optimize different extraction methods of Lamiophlomis rotata Kudo. METHODS: With the content of total flavonoids as assay index, the effect of three extraction methods was compared and the optimal excracting technology was selected by orthogoral test. RESULTS: The contents of flavonoids and solids by ethanol extraction were more than that by the boiling water extraction and ultrasonic extraction. CONCLUSION: The ethanol extraction is the optimal extracting technology, which is to put 10g powder of Lamiophlomis into 200ml 60% alcohol, and then reflux extract for 25 min. |
