1State Key Laboratory of OSSO, Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, Lanzhou 730000, China.
Objective:
To study the chemical constituents from Lamium maculatum var. kansuense.
Method:
The chemical constituents were isolated and repeatedly purified on silica gel column and the structures were elucidated by the NMR spectra and physico-chemical properties.
Result:
Six compounds were obtained and identified as polypodine B (I), 5-OH-8-epiloganin (II), shlanzhiside methyl ester (III), liriodendrin (IV), quercitroside (V), uridine (VI).
Conclusion:
Compound IV was found from genus Lamium for the first time and the rest of the compounds were found from Lamium maculatum var kansuense for the first time.
