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 few species in the genus Adonis are the only land plants known to produce the valuable red ketocarotenoid astaxanthin in abundance. Here, we ascertain the pathway that leads from the β-rings of β-carotene, a carotenoid ubiquitous in plants, to the 3-hydroxy-4-keto-β-rings of astaxanthin (3,3'-dihydroxy-β,β-carotene-4,4'-dione) in the blood-red flowers of Adonis aestivalis, an ornamental and m...

The object of this research is the herb Adonis vernalis and hydroalcoholic extracts obtained on its basis. By nature action, drugs belong to group cardiac glycosides occupy an intermediate place between strophanthin digitalis. In official medicine, biologically active compounds are included in such as Cardiovalen, Adonis-bromine, Caridiolin Cardiophyte. extemporal formulation, extract part Bech...

Chemical investigation of the seeds of Adonis aestivalis has led to the isolation of a new cardenolide (3β,5α,14β,17β-tetrahydroxycard-20,22-enolide) (1), two new glycosides (2, 3) of 1, and a new strophanthidin hexaglycoside (4), together with a known compound, strophanthidin 3-O-β-D-glucopyranoside (5). The structures of 1-4 were determined by 1D- and 2D-NMR spectroscopic analysis and the res...

OBJECTIVES The objective of this study was to analyze the fatty acid content, antioxidant, and antibacterial activities of hydro-methanolic extract of Adonis wolgensis L. (A. wolgensis L.) growing wild in north of Iran. MATERIALS AND METHODS Oils of A. wolgensis L. was obtained by means of Soxhlet apparatus from leaves and stems. Methyl esters were derived from the oily mixtures by trans-este...

Imidacloprid, a relatively long residual neonicotinoid soil insecticide, is often applied to lawns and golf courses in spring for preventive control of root-feeding white grubs. We evaluated effects of such applications on spring parasitism of the overwintered third-instar Japanese beetle, Popillia japonica Newman, by Tiphia vernalis Rohwer, an introduced solitary ectoparasitoid. Natural rates ...
