Hawthorn (Crataegus spp.) fruit: Some physical and chemical properties
Scopus
Toplam 115 atıf DOI
The hawthorn (Crataegus spp.) fruits were analysed for some physical (dimensions, geometric mean diameter, sphericity, bulk density, fruit density, volume, terminal velocity, hardness and porosity) and chemical (moisture, crude protein, crude oil, crude energy, crude fiber, ash, pH, acidity, water- and alcohol soluble extract) properties. Mineral content of wild hawthorn growing in Turkey were determined by Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AES). All materials contained high amounts of Ca, K, Mg, Na and P. These values were found as 3046.37 ppm, 13,531.96 ppm, 1502.55 ppm, 312.18 ppm, 1477.88 ppm and 431,307.29 ppm, respectively. The mean pulp and seeds weight, length, diameter, mass, volume, geometric mean diameter, sphericity and projected area were measured as 2.16 g, 0.87 g, 14.39 mm, 19.34 mm, 3.03 g, 3083.3 mm3, 17.52 mm, 1.22 and 4.19 cm2, respectively. The energy, protein, cellulose, oil, ash, acidity and water-soluble extract values of hawthorn fruits were established as 34.02 kcal/g, 2.48%, 4.67%, 0.87%, 2.28%, 1.98% and 32.31%, respectively. It is very important to evaluate the physical properties for the design of equipment used for harvesting, transportation, storage and processing of fresh fruits. Also, the information supplied on the chemical properties of the hawthorn fruit can be used in human nutrition. © 2004 Elsevier Ltd. All rights reserved.

BACKGROUND: In this investigation, the chemical and biological profiles of three Turkish Crataegus species (Crataegus orientalis, Crataegus szovitsii and Crataegus tanacetifolia) were studied in order to provide the first comprehensive characterization and their health-promoting potential. In this respect, polyphenolic profiles were evaluated using ultrahigh-performance liquid chromatography–quadrupole time-of-flight mass spectrometry. The in vitro antioxidant activities of the Crataegus samples were evaluated by using free-radical scavenging, phosphomolybdenum, ferrous-ion chelating, and reducing power assays. The inhibitory activities against α-glucosidase, amylase, cholinesterases (acetylcholinesterase (AChE) and butyrylcholinesterase (BChE)), and tyrosinase were also established. RESULTS: The untargeted metabolomic approach highlighted the effect of both extraction types and species on the phenolic profiles of different Crateagus tissues (i.e. leaves and twigs). The methanolic extracts showed the maximum radical scavenging and reducing activity in all test systems, whereas for ferrous-ion chelating assays the decocted and infused extracts showed the highest activity. Only the methanolic extracts were effective against AChE and BChE. The extract tested showed remarkable inhibitory effects against tyrosinase and α-glucosidase, whereas all the extracts exhibited modest inhibition against α-amylase. Overall, the twig extracts of the three species studied showed superior antioxidant and enzyme inhibitory activities. CONCLUSION: On the basis of these results, the three Crataegus species can be classified as potent bioresources for high-value phytochemicals, which warrant further investigations for developing novel nutraceuticals. © 2019 Society of Chemical Industry.
