Diterpenoid and triterpenoid glycosides from Clinopodium chinense .

Two new compounds, including a diterpenoid glycoside ( 1 ) and a triterpenoid glycoside ( 6 ), along with six known compounds were isolated from Clinopodium chinense . The structures of the new compounds were determined on basis of extensive spectral analysis and chemical method. Compounds 1 - 8 were evaluated for their insulin resistance effect and cytotoxic activity against the A549 and HepG2 cancer cell lines. None of the compounds were cytotoxic (IC ₅₀  > 100 μM), while compounds 1 - 3 and 5 showed the activity of ameliorating insulin resistance in HepG2.
