Abstract

Objective: To study the best technology of the extraction of triterpenoids from the stems of Hyptis suaveolens with microwave.

Methods: Orthogonal experiment was carried out to investigate 4 influential factors as follows: the time (A), the temperature (B), the solid fluid compared to (C), the NaOH density (D).

Results: The optimal conditions for microwave extraction were A1 B2 C3 D2.

Conclusion: The microwave extraction can extract more triterpenoids from the stems of Hyptis suaveolens in shorter time with less energy. It also shows a promising prospect for leaching the effective constituents from Chinese herbal medicine by using microwave extraction.
