This paper presents the distribution of the terrestrial isopod Hyloniscus adonis (Verhoeff, 1927) in croatia. It was recorded for the first time at the edge of Dubravica peat bog and the adjacent forest. Additionally, it was collected at the edges of Đon močvar peat bog. Revision of the terrestrial isopod collection of the Croatian Biospeleological Society revealed that this species also occurs...
Adonis aestivalis (summer pheasant-eye) is an annual plant with a crimson flower, distributed in southern Europe and Asia. The plant has large buttercup-like blossoms and soft, fern-like leaves. It blooms in spring and is often found as a weed in cereal fields. Like other Adonis spp., the plant produces cardiac glycosides. It is used in remedies for mild weakness of the heart, especially when a...
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...
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...
Astaxanthin is a kind of important carotenoids with powerful antioxidation capacity and other health functions. Extracting from Adonis amurensis is a promising way to obtain natural astaxanthin. However, how to ensure the high purity and to investigate related substances in astaxanthin crystals are necessary issues. In this study, to identify possible impurities, astaxanthin crystal was first e...
Karyotypes and genome size of Adonis amurensis and Adonis apennina (Ranunculaceae) from Asian Russia
The process of data taking, reduction and calibration of near-infrared imaging polarimetry data taken with the ESO Adaptive Optics System ADONIS is described. The ADONIS polarimetric facility is provided by a rotating wire grid polarizer. Images were taken at increments of 22.5 of polarizer rotation from 0 to 180, oversampling the polarization curve but allowing the effects of photometric varia...
