Material

The stems   (known as Mahuang) and roots (known as Mahuanggen) of Ephedra sinica.

Results

Mahuang was   rich in ephedrine-type alkaloids, while Mahuanggen was rich in macrocyclic   spermine alkaloids. Additionally, different types of flavan-3-ols and   flavones exist in Mahuang and Mahuanggen extracts.

Material

Mahuang (MH,   the stems of Ephedra sinica) and   Mahuanggen (MHG, the roots of Ephedra   sinica)

Results

MH samples had   significantly higher content of two reported pharmacologically important   chemical markers of TMP and α-terpineol, which may account for their   different antioxidant activities.
