Chrysoeriol derivatives and other constituents from Glandularia selloi

Perplexing Polyphenolics: The Isolations, Syntheses, Reappraisals, and Bioactivities of Flavonoids, Isoflavonoids, and Neoflavonoids from 2016 to 2022

“…Compounds 3 and 4 were isolated from the aerial parts and roots of Glandularia selloi and are glycosylated derivatives of chrysoeriol. They are acylated disaccharides and are the first acylated flavone O -glycosides to be isolated from the Verbenaceae family [ 21 ]. Compounds 5 and 6 were isolated from the gametophytes of Ceratodon purpureus and were fully characterized for the first time.…”

“…Compounds 3 and 4 did not exhibit significant inhibition of leukocyte chemotaxis [ 21 ]. Compound 5 was considerably more potent than rutin (IC 50 : 38.6 μM), a powerful antioxidant.…”

“…One of the best sources to evaluate the molecular weight or m/z of any compound of the "PubChem" site is that Ipolamiide (PubChem CID: 442425) with a m/z of 424.1822 appears to be a terpene compound with a molecular weight of 406.4 g/mol (M-H ~ 405 g/mol and M+H ~407 g/mol) (2,3). Other combinations of this compound (glucoside or 6β-hydroxy-ipolamiide) can have different molecular weights that the type of which is accurately mentioned (4). Other compounds also appear as follows: Decenedioic acid, with a molecular weight of 200.23 g/mol, PubChem CID: 181528, M-H ~199 g/mol and M+H ~201 g/mol while the m/z is mentioned in article 218.1384 (5), 2,3-dinor Thromboxane B 1 (2,3-Dinor-TXB1), with a molecular weight of 342.5 g/mol, PubChem CID: 52921884, M-H ~341 g/mol and M+H ~343 g/ mol while the m/z is mentioned in article 362.2541 (6).…”

“…Homoesperetin 7-rutinoside, with a molecular weight of 624.6 g/mol, PubChem CID: 42607988, M-H ~623 g/ mol and M+H ~ 625 g/mol while the m/z is mentioned in article 642.2401 (7) and 11-hydroperoxy-12,13epoxy-9-octadecenoic acid, with a molecular weight of 328.4 g/mol, PubChem CID: 5282862, M-H ~327 g/mol and M+H ~329 g/mol while the m/z is mentioned in article 346.259 (8). Since two factors (Acquisition time and Counts (Mass-to-charge) ×10 4 ) are important in identifying compounds in interpreting the results of the LC-MS, it is best to compare the results with respect to these two factors in Tables 1-5. In addition, in the LC-MS technique, all the peaks recorded in the chromatogram are recorded precisely according to the Acquisition time and Counts (Mass-to-charge) ×10 4 of each, so it is best to add all peaks in the tables accurately (9).…”
