Spectral features of c methylflavones






Khimiya Prirodnykh Soedinenii (3): 306-309

Spectral features of c methylflavones

The properties of nor-eucalyptin, methylapigenin, eucalyptin, sideroxylin, dimethylapigenin, silpin and dimethylsilpin isolated from Eucalyptus viminalis (Myrtaceae), Ledum palustre, (Ericaceae) and Pinus sylvestris (Pinaceae) were studied. Data were presented on their mass and UV spectra.
