Abstract Leontopodic acid—a novel full substituted hexaric acid derivative, was isolated from the aerial parts of Edelweiss ( Leontopodium alpinum Cass.) as one of the major compounds. The complex structure of leontopodic acid-2-[(3 S )-3-hydroxybutanoate]-3,4,5-tris-[(2 E )-3-(3,4-dihydroxyphenyl)-2-propenoate]- d -glucaric acid—was elucidated by mass spectrometry, 1D- and 2D NMR spectroscopy and HPLC monitored transesterification. Leontopodic acid exhibited pronounced antioxidative effects in… Expand

Analysis of hydroxycinnamic acids derivatives in calafate (Berberis microphylla G. Forst) berries by liquid chromatography with photodiode array and mass spectrometry detection.
It is suggested that calafate could be considered a very interesting fruit from the point of view of their nutraceutical composition, despite of the high anthocyanin concentrations, showing a much higher concentration of these acids than other widely consumed berries. Expand
Phenylpropanoid profiling reveals a class of hydroxycinnamoyl glucaric acid conjugates in Isatis tinctoria leaves.
The brassicaceous herb, Isatis tinctoria, is an ancient medicinal plant whose rosette leaf extracts have anti-inflammatory and anti-allergic activity and a large amount of hydroxycinnamic acid derivatives changes radically the view of the woad metabolite profile and potentially contributes to the pharmacological activity of I. tinctoria leaf extracts.
