Summary of "Chemical basis of hawthorn processed with honey protecting against myocardial ischaemia."

Hawthorn including many plants from the genus Crataegus (C.) is used for traditional medicines, herbal drugs, and dietary supplements all over the world. In China, C. pinnatifida Bge. var. major N, E. Br, and C. pinnatifida Bge. are two major species that are used as hawthorn. The purpose of this study is to assay the myocardial protection of hawthorn fruit processed with honey (MSZ) and screen the chemical basis of MSZ on this effect. Firstly, ultra-performance liquid chromatography-quadrupole time of flight-mass spectrometry (UPLC/Q-TOF-MS) was used to analyze the chemical constituents of the sliced dry fruit of hawthorn (SZ) and MSZ. Principal component analysis (PCA) was used to differentiate them. Orthogonal partial least squares-discriminate analysis (OPLS-DA) was applied to screen different compounds between SZ and MSZ, and 32 different compounds were selected. Then a pharmacodynamic test to investigate their protective effect against myocardial ischaemia was carried out. The results demonstrated that the protective effect of MSZ was better than that of SZ on the same dose. Finally, the chemical basis for the protective effect provided by MSZ against myocardial ischaemia was speculated based on correlation analysis. Taken together, all these results suggest that phenylpropanoids, organic acids, tannins, and flavonoids might be the chemical basis of MSZ protecting against myocardial ischaemia.

Medical and Biotech [MESH] Definitions

A sweet viscous liquid food, produced in the honey sacs of various bees from nectar collected from flowers. The nectar is ripened into honey by inversion of its sucrose sugar into fructose and glucose. It is somewhat acidic and has mild antiseptic properties, being sometimes used in the treatment of burns and lacerations.

The medical use of honey bee products such as BEE VENOM; HONEY; bee pollen; PROPOLIS; and royal jelly.

Mucins that are found on the surface of the gastric epithelium. They play a role in protecting the epithelial layer from mechanical and chemical damage.

Genes bearing close resemblance to known genes at different loci, but rendered non-functional by additions or deletions in structure that prevent normal transcription or translation. When lacking introns and containing a poly-A segment near the downstream end (as a result of reverse copying from processed nuclear RNA into double-stranded DNA), they are called processed genes.
