Crataegus monogyna Jacq. is naturalized in North America, where it has hybridized with native diploid hawthorns at least twice. We provide names for the two nothospecies (as well as for the corresponding nothosections and nothoseries), referring to existing documentation in the literature for nothosp. nov. Crataegus ×ninae-celottiae K.I. Chr. & T.A. Dickinson (C. monogyna × C. punctata Jacq.). ...

H awthorn, a Crataegus species, is part of a genus of spiny shrubs and trees native to temperate regions in the Northern Hemisphere in Europe, Asia, and North America. Depending on the taxonomic interpretation, between 200 and 1,000 species of Crataegus have been recognized. Hawthorn is the oldest known medicinal plant in European medicine; its actions on the heart were first described by Diosc...

A phytochemical study of two plant species, Viscum cruciatum Sieber and Crataegus monogyna Jacq., was completed to investigate the influence of the parasite Viscum cruciatum on the host Crataegus monogyna. The study was carried out with two samples and consisted of hexane extracts of the Viscum cruciatum parasitizing on Crataegus monogyna and C monogyna. In these samples ursolic acid, beta-sito...

Illicium verum (badiane or star anise), Crataegus oxyacantha ssp monogyna (hawthorn) and Allium cepa (onion), have traditionnally been used as medicinal plants in Algeria. This study showed that the outer layer of onion is rich in flavonols with contents of 103 ± 7.90 µg/g DW (red variety) and 17.3 ± 0.69 µg/gDW (white variety). We also determined flavonols contents of 14.3 ± 0.21 µg/g 1.65 ± 0...

Investigations on procyanidin profile on Bulgarian Crataegus oxycantha fruits extract has been carried out by different analytical approaches based on chromatographic methods. We retained of interest to test the validity of direct infusion of Crataegus extract in ESI conditions to achieve an immediate fingerprinting of the procyanidins therein contained. The results are compared with those obta...
