Flavonoids mints

Negative atmospheric pressure chemical ionization (APC) low-energy collision activation mss spectrometry has also been employed for the characterization of flavonoids in extracts of fresh herbs. Besides the separation, quantitative determination and identification of flavonoids, the objective of the study was the comparison of the efficacy of the various detection systems in the analysis of flavonoids in herb extracts. Freeze-dried herbs (0.5g of chives, cress, dill, lovage, mint, oregano, parsley, rosemary, tarragon and thyme) were ground and extracted with 20 ml of 62.5 per cent aqueous methanol. After sedimentation the suspension was filtered and used for HPLC analyses. Separations were carried out in an... 

The determination of the antioxidant activity and phenolic profile of various tea and herbal infusions were recently reported. Atoui et al. [67] applied TEAC and luminol PCL assays to assess the antioxidant activity, and positive-ion LC-DAD-ESI-MS to assess the phenolic profile in 9 different teas, including Greek mountain tea, mint, chamomile, black Ceylon, and Chinese green tea. About 60 different flavonoid and phenolic acid derivatives were identified.
