METHODS
The essential substance (G4) was extracted from the root by alcohol and ethyl acetate, then it was separated by silica gel column eluted
The effects of low levels of heavy metals on plant growth, biomass turnover and reproduction were investigated for Hieracium pilosella. Plants were grown for 12 weeks on substrates with different concentrations of heavy metals obtained by diluting contaminated soils with silica sand. To minimize
