Clinopodiside A is a natural product from Clinopodium chinense.

The separation was performed in two steps with two different kinds of solvent systems. In the first step, ethyl acetate-1-butanol-water (5:0.8:5, v/v) was used as the two-phase solvent system; nairutin was purified, and didymin and Clinopodiside A were eluted together. In the second step, ethyl acetate-methanol-water (5:1:5, v/v) was used as the two-phase solvent system; didymin and Clinopodiside A were separated and purified. After two-step separation, 15.2 mg of nairutin, 39.1 mg of Clinopodiside A, and 20.6 mg of didymin were obtained from 100 mg of crude extract with purities of 96.5%, 98.4%, and 99.1%, respectively, as determined by HPLC analysis. The chemical structures of the three components were confirmed by 1H NMR and 13C NMR.
