Determination of polyphenolic compounds in commercial herbal drugs and spices from Lamiaceae: thyme, wild thyme and sweet marjoram by chromatographic techniques
چکیده انگلیسی

HPLC and HPTLC methods were used for a qualitative and quantitative determination of luteolin-7-O-β-glucuronide, lithospermic acid, rosmarinic acid and mthyl rosmarinate, together with other known compounds, in commercial herbal drugs and spices from lamiaceous species: Thymi herba, Serpylli herba and Majoranae herba. The contents of analyzed compounds in the studied hydrophilic extracts, prepared form herbal sources, were established using a C18 column with acetonitrile–water–formic acid as a mobile phase. The HPLC method was validated for linearity, precision and accuracy. Luteolin-7-O-β-glucuronide and lithospermic acid were identified as new wild thyme constituents, luteolin-7-O-β-glucuronide and methyl rosmarinate as new compounds in sweet marjoram. Methyl rosmarinate was isolated for the first time from thyme. The investigated herbal drugs and spices provide polyphenols in high amounts, even up to 84.3 mg per 1 g of a dried herb.
