Adonis vernalis

Partial Purification and Characterization of d-Ribose-5-phosphate Reductase from Adonis vernalis L. Leaves.

This study presents evidence for a new enzyme, d-ribose-5-P reductase, which catalyzes the reaction: d-ribose-5-P + NADPH + H(+) --> d-ribitol-5-P + NADP(+). The enzyme was isolated from Adonis vernalis L. leaves in 38% yield and was purified 71-fold. The reductase was NADPH specific and had a pH optimum in the range of 5.5 to 6.0. The Michaelis constant value for d-ribose-5-P reduction was 1.3...

THE STUDY OF BLOOMING AND POLLEN EFFICIENCY OF Adonis vernalis L. IN XEROTHERMIC PLANT COMMUNITIES

The study was conducted in the years 2004 – 2005 using two populations of Adonis vernalis L. occurring in the Adonido-Brachypodietum pinnati community at Pliszczyn near Lublin and in the Brachypodio-Teucrietum community at Stawska Góra near Che3m. The blooming of A. vernalis in the Lublin region occurs from the first days of April to the end of May. The species is characterized by an early, day...

A new flavonol glycoside from Hylomecon vernalis.

Purification of a MeOH extract from the aerial parts of Hylomecon vernalis Maxim. (Papaveraceae) using column chromatography furnished a new acetylated flavonol glycoside (1), together with twenty known phenolic compounds (2-21). Structural elucidation of 1 was based on 1D- and 2D-NMR spectroscopy data analysis to be quercetin 3-O-[4‴-O-acetyl-α-L-arabinopyranosyl]-(1‴→6″)-β-D-galactopyranoside...
