Antioxidant activity of Crataegus Monogyna L flowers

Crataegus species are known by their biological effects for many years. Crataegus monogyna Jacq. flowers have been ethnomedically used in different parts of Turkey for their many biological effects such as against tachycardia and sedative, antihypertensive, antispasmodic and diuretic. In addition to the widespread use of Crataegus species, many pharmacopoeias and monografts are registered, and a large number of in vitro, in vivo and clinical studies have been carried out with respect to bioactivity and mechanism of action. In vitro, leaves and fruits of Crataegusspecies have also been shown to exhibit antioxidant. However, these properties are influenced by the type of plant organ, the harvest season, the species and the geographical origin. In this contex, different extracts of ripe flowers of Crataegus monogyna (CM) collected from natural habitats on the limit of Konya/Seydişehir-Turkey at September 2015 were evaluated for their antioxidant capacity. Rutin contents was determined as 2.68 μg/ml in ethanolic extract of Crataegus monogyna Jacq., % ABTS· radical scavenging activity of the extract is 78.80±4.09 and 1.080±0.08 μg trolox/mg extract in CUPRAC method. In conclusion, the results of this study indicate that flowers of Crataegus monogyna provide considerable antioxidant protection and can be suitable raw material for the medicine, food and cosmetic industries.
