Polyploidy plays a prominent role in the speciation process in plants. Many species are known to be part of agamic complexes comprising sexual diploids and more or less exclusively asexual polyploids. However, polyploid formation has been studied in very few cases, primarily because of the challenges in examining these cases phylogenetically. In this study, we demonstrate the use of a variety o...

A review with 54 references covers all aspects of hawthorn, the genus Crataegus, including its traditional uses, chemical constituents, pharmacological activities, and clinical effects. Although the effectiveness of hawthorn on the treatment of cardiovascular diseases has received extensive attention worldwide, further scientific research on various areas such as pharmacokinetics, mechanism of ...

The present study was carried out to study the effect of antioxidants on oxidised LDL + VLDL and found that vitamin E, eugenol and tincture of crataegus (antioxidants) inhibited oxidation of (LDL + VLDL) similar to standard antioxidant (butylated hydroxy toluene). Vitamin C acted as an antioxidant at lower concentration, and prooxidant at higher concentration.

An agamic complex of 20- and 10-stamen, black-fruited hawthorns (Crataegus subg. Sanguineae, sect. Douglasianae) occurs in western North America, with a 10-stamen taxon disjunct the upper Great Lakes basin. Here, we recircumscribe 20-stamen taxa at core this (C. ser. Douglasianae). This is needed order to distinguish between presumptively ancestral diploid its allo- autopolyploid derivatives, a...

introduction: despite extensive studies about effects of crataegus monogyna on cardiovascular diseases yet, a few study has been undertaken antiarrhythmic property of this plant. aims of the present study were: 1) to determine the protective role of methanolic extract of c.monogyna on the rate-dependent model and the concealed conduction . 2) to explore the role of na+-k+ a tpase in the protect...

[1] We use Interferometric Synthetic Aperture Radar (InSAR) to search for surface deformation in the southern Andes (40 S–46 S and 49 S–53 S) associated with magmatic processes. Although the available data are not optimal, we can constrain the amount of volcanic deformation at about 27 Holocene volcanoes between the years 1993–1999. We detect inflation of Cerro Hudson volcano following its 1991...

A New pregnane type Alkaloid named Sracosalgminol [(20S)-20-(dimethylamino)-3β-methoxy-16β-hydroxyl-pregn-5-ene] was isolated from sarcococca saligna and its structure was established on the basis of spectroscopic techniques includingH,13C-NMR and inverse 2D-NMR techniques (DEPT,HMQC and HMBC) UV,MS etc.
