Studies on the quantitative and qualitative composition of phenolic compounds in healthy apple leaves and leaves with scabs have been conducted to evaluate the influence of apple scab (Venturia inaequalis (Cooke) Wint ) on the biosynthesis of phenolic compounds [1 2] However there is still a lack of studies of apple leaves which would allow for their use in medical practice pharmacy and

HPLC-DAD quantitative analysis of leaf phenolic compounds Lyophilized leaves (1 5 g per sample) were extracted with 300 ml of boiling water for 20 min with subsequent filtration The resulting extracts were lyophilized and maintained in a dessicator at room temperature in the dark Lyophilized extracts were dissolved in water (100 mg ml −1) and analysed using an HPLC unit (Gilson) and a

Plums (Prunus domestica L and Prunus salicina L ) are edible fruits mostly consumed in America China and Europe We have used LC-MSn to detect and characterize the phenolic compounds in plum varieties Forty-one phenolics were detected comprising caffeoylquinic acids feruloylquinic acid p-coumaroylquinic acids methyl caffeoylquinates methyl p-coumaroylquinate caffeoylshikimic acids

The phenolic compounds were separated on a C18 column (4 6 150 mm 1 8 μm) with 1% formic acid in water/acetonitrile 90:10 v/v and acetonitrile as mobile phases The accuracy mass data generated by TOF-MS together with the fragmentation pattern obtained by IT-MS2 experiments confirmed the presence of 25 and 30 phenolic compounds in the aqueous and ethanolic extracts respectively
