The content of phytochemicals associated with the antioxidant activity of the fruits of species of hawthorn (Crataegus spp.; Rosacea) located in Mexico is unknown. The objective of the present study was to evaluate the content of phenolic compounds, flavonoids, vitamin C and the antioxidant activity in a selection of Mexican hawthorn species. A quantification was made of total phenols, flavonoi...

Both edible fungal polysaccharides (Auricularia and Tremellan) Crataegus flavonoids promote the balance of dyslipidemia, which have a positive biological regulating effect on intestinal flora. In this study, extraction water-soluble from Auricularia Tremellan was investigated optimized firstly. Polysaccharides were then combined to study effects mediating role abnormal blood lipid concentration...

The use of Crataegus species for the treatment cardiovascular ailments is widely distributed. Even then only a few are included in Pharmacopoeias. In this study bioactive flavonoids azarolus and pallasii were identified quantified comparison with well-known pharmaceutical product Crataegus; Crataegutt® Tropfen using reverse phase-high performance liquid chromatography. method developed simple, ...

The purpose of the current study was to investigate the effect of a high- intensity treadmill running (8 weeks) with or without aqueous extraction of black Crataegus-Pentaegyna (Siyah -Valik) on liver ABCA1 mRNA expression and plasma HDL-C, total, and direct bilirubin concentration in male rats. Twenty Wistar male rats (4-6 weeks old, 140-170 g weight) were used. Animals were randomly assigne...

Many tyrosinase inhibitors have been alleged to have serious side effects. To search for relatively mild and safe tyrosinase inhibitors, two new 8-O-4′ neolignans, named huangnin A (1) and B (2), and four known analogs (3-6) were isolated from the seeds of Crataegus pinnatifida. Their structures were elucidated by spectroscopic analyses (1D, 2D NMR, HRESIMS, CD and Rh2(OCOCF3)4-induced CD). In ...
