Objective:
To study the chemical constituents from Lamium maculatum L. var Kansuense.
Method:
The chemical constituents were isolated and repeatedly purified by silica gel column chromatography and the structures were elucidated by the NMR spectra and physico-chemical properties.
Result:
Ten compounds were obtained and they were identified as D-mannitol, beta-sitosterol, stigmasterol, rutin, 3'-methylquercetin-3-O-rutinoside, n-butyl-beta-D-fructopyranoside, daucosterol, acteoside, 20-hydroxyecdysone, allantoin.
Conclusion:
All the compounds were obtained from L. maculatum L. var Kansuense for the first time.
