## Abstract ^13^C CP/MAS NMR spectra were recorded to characterize the solidβstate conformation of flavonoids: galangin, kaempferol, quercetin, myricetin, chrysin, apigenin, luteolin, acacetin, hesperetin and naringenin. Correct assignment of the signals in solutionβstate spectra (using APT, HSQC a
Monotrimethylsilylated flavonoid methyl ethers were studied with electron impact mass spectrometry, and derived from natural compounds by methylation, hydrolysis and trimethylsilylation. Spectra were compared with those of the permethylated fiavonoid. Fragment ions were distinguished among the vario
