OBJECTIVE: To optimize the extraction conditions of total alkaloids from Bidens bipinnata by microwave extraction. Methods: The orthogonal design of L9 (34) was used to optimize the microwave extraction conditions of total alkaloids from Bidensgrass. Results: The optimum extraction conditions for total alkaloids from Bidensgrass were A3B3C2D1. The volume fraction of solvent had a great influence on the extraction. Conclusion: The optimized extraction conditions are efficient and can increase the utilization rate of Bidensgrass.
