“…Three derivatives of vitexin were found in the leaf preparation; two of them (vitexin and vitexin-2′′- O -rhamnoside) were the same as that in the bark preparation, and a new acetylvitexin-2′′- O -rhamnoside peak 24 (Rt 10.75 min, λ max 340 nm) produced ions [M-H] at 619.1664 m / z . The same kind of compounds in the Crataegus leaves were found by Ding et al (2010). Two compounds, 16 and 17 (Fig.…”

The aim of the study was to identify and determine the percent content of polyphenols in extracts from leaves and hawthorn bark, to examine the effect of the extracts on the properties of the biological membrane as well as to determine their antioxidant activity toward membrane lipids. In particular, a biophysical investigation was conducted on the effect of hawthorn extracts on the osmotic resistance and morphology of erythrocyte cells and on the packing of the heads of membrane lipids. Analysis of the polyphenol content of extracts used the HPLC method. Analysis of the polyphenol composition has shown a dominant share of procyanidins and epicatechin in both extracts. The research showed that the polyphenolic compounds contained in hawthorn extracts are incorporated mainly into the hydrophilic part of the erythrocyte membrane, inducing echinocyte shapes. They also diminish the packing order of the lipid polar heads of the membrane, as evidenced by the lowered generalized polarization values of Laurdan. The substances used induced increased osmotic pressure of erythrocytes, making them less sensitive to changes in osmotic pressure. The presence of the extract compounds in the outer hydrophilic part of the erythrocyte membrane, evidenced by examination of the shapes and packing in the hydrophilic part of membrane, indicates that the substances constitute a kind of barrier that protects the erythrocyte membrane against free radicals, while the membrane-bound extracts do not disturb the membrane structure and, thus, do not cause any side effects.

“…The most interesting fragments concern the base peaks at m/z 179 ( [8,9]. According to the data published by Simirgiotis [10], this compound was suggested to be Isoquercitrin (quercetin 3-O-glucose), which were identified previously in hawthorn [11,12], by comparison with authentic compounds showed a molecular anion at m/z 463. The compound has the same mass spectrum behavior detected in negative mode, in particular using the ESI ion trap detector ( Another new three reported compounds are gossypetin-O-diglucoside, gossypetin-O-glucoside -O-glucoronide, and gossypetin-O-glucoronide.…”

Genus Talipariti has long history of use in various traditional medicine therapeutic applications in Cuba, especially in treatment of bronchial asthma and flu. Petals of genus Talipariti are rich source of secondary metabolites and most of these metabolites are reported to possess expectorant, antasthmatic, appetitive, antioxidant, and antibacterial properties. Hence, in our study, we present a validated, sensitive, reliable, and cheap narrow-bore UHPLC-UV-ESI-MS/MS coupled to PDA (photodiode array detectors) method for the simultaneous isolation and identification of flavonoids and their glycosidic derivatives in this flower drug. In addition, about twelve compounds were identified in this specie based on chromatography retention time (t R ), UV and MS/MS spectra and compared with those of isolated authentic compound and literature data. About eighth constituents were reported for the first time from Talipariti elatum. Our results demonstrated the developed method could be employed as a rapid and versatile analytical technique for identification of chemical constituents and quality control of Talipariti elatum.

The red petals of the flowers of Talipariti elatum, commonly named majagua is used as antitussive, expectorant and antasthmatic in phytotherapy, although the plants' composition has not been determined in detail so far. Hence, in this study, we present a validated, sensitive, reliable, and cheap narrow-bore LC-UV-ESI-MS/MS coupled to PDA (photodiode array detectors) method for the simultaneous isolation and identification of flavonoids and their glycosidic derivatives in this flower drug. In addition, the structures of two compounds have been elucidated by LC-MS experiments after isolation. Structure analyses allow proposing the presence of gossypitrin (gossypetin-7-Oglucoside) or gossypetin-3'-O-glucoside, a quercetin derivative, possibly quercetin-3-O-glucoside and an unidentified compound with an impair number of m/z, probably an alkaloid.
