Aim to study the effect of the hawthorn shoots on kidney excretory function.
 Material and methods. We used the shoots of Crataegus sanguinea Pall., Crataegus monogina Jacq. and Crataegus submollis Sarg. harvested during the flowering period in the arboretum of the Botanical Garden of Samara University in 2021. The raw material of each type, separately, was used in fractional maceration with 70% ethyl alcohol for creation liquid extracts, then, after extractant removal, the thick extracts were obtained. The thick extracts were processed with differential spectrophotometry method to calcul

Abstract:
Background: myocardial ischemia-reperfusion (I/R) injury may occur in a variety of clinical settings and this remains a significant problem. Oxygen free radicals, produced on reperfusion have been shown to play a major role in myocardial I/R injury. Various therapeutic effects have been described for Crataegus. Additionally, it has been presented that Crataegus has protective effect against ischemia reperfusion induced myocardial injuries to various organs. Therefore, it seems possible that the administration of Crataegus might protect the heart against the ischemia reperfusion injury.Objectiv

Abstract:
An extract of Crataegus-WS 1442-standardized by a special process of production and adjusted to 18.75% oligomeric procyanidines, was investigated in single and repeat-dose toxicity studies. No target organ toxicity was defined at high multiples of the human dose (100 times) and the battery of standard mutagenic and clastogenic tests were negative. The results presented are for Crataegus extract WS 1442 only; other preparations of Crataegus have to be investigated case by case.

The flowers and fruits of various species of the hawthorn genus (Crataegus L.) are widely used in domestic and foreign medical practice as cardiotonic agents. A perspective species for collecting of the raw material is Crataegus submollis Sarg. It was determined that 70% ethanol is an optimal extragent for the extraction of flavonoids from Crataegus submollis Sarg. flowers. The content of the total flavonoids in terms of hyperoside in the liquid extract of Crataegus submollis Sarg. flowers is 0,24 0,01%.

Abstract:
The contraction of aortic tissues induced by 50 mM KCl is primarily mediated through the activation of voltage-dependent L-type Ca2+ channels in smooth muscle cells. In this study, the effects of Crategus Rosaceae and Inula helenium extracts on KCl-induced contraction were investigated. Extracts of Crataegus attenuated the KCl-induced contraction by 15.0 ± 2.6 and 70.0 ± 2.8 % at concentrations ranging from 20 - 70 μg/mL, while Inula helenium extract reduced the contraction by 5.0 ± 3.1 and 80.0 ± 2.8 % at concentrations of 10 - 50 μg/mL.

Among the different Hawthorn species, Crataegus monogyna seems to be one of the most often used in herbal medicine, and is commercially available. The methanolic extract and the acidified methanol extract of an herbal medicinal product based on Crataegus monogyna inflorescences were analyzed by using high-pressure liquid chromatography/electrospray ionization mass spectrometry (HPLC/ESI-MS). On the basis of m/z of [M-H]− ions and characteristic fragmentation patterns, a number of polyphenolic compounds, namely flavonoids and chlorogenic acids, were identified.
