[Orthogonal experiment of the extraction of triterpenoids from stems of Hyptis suaveolens with microwave].
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.


CONCLUSIONS
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.
