TL;DR: The results of the present study support the development of natural bioactive compounds as cancer chemotherapeutics by revealing that isovitexin gratifies pharmacokinetic bioavailability parameters as evidenced by Lipinski rule and ADMET profile.

TL;DR: A 2''-O-glycosyltransferase ZjOGT38 was identified from Ziziphus jujuba as mentioned in this paper , which could regio-selectively glycosylate 2-hydroxyflavanone C-glycoides.

TL;DR: The results indicate that the process of cultivation has had a noticeable effect on flavonoid synthesis in barley leaves and they confirm the taxonomic status of the H. vulgare complex from all the other species.
Abstract: Seven flavonoids have been identified variously in leaf extracts of 18 wild Hordeum species. Six are C-glycosylflavones. namely isovitexin. iso-orientin and iso-orientin 3′-methyl ether and the respective 7-0-glucosides. The seventh is the flavone 0-glucoside. tricin 5-glucoside. Several other C-glycosylflavones based on iso-orientin 3′-methyl ether are present in trace amounts. The pattern is essentially a simple one, with little variation between species. It contrasts markedly with the much more complex pattern of flavonoids found in different races of cultivated barley. The results indicate that the process of cultivation has had a noticeable effect on flavonoid synthesis in barley leaves and they confirm the taxonomic separation of the H. vulgare complex from all the other species.

TL;DR: In this article, a high-performance thin-layer chromatographic method was developed, validated, and used for quantification of isovitexin in dried whole-plant powder of Enicostemma littorale Blume.
Abstract: A sensitive and accurate high-performance thin-layer chromatographic method has been developed, validated, and used for quantification of isovitexin in dried whole-plant powder of Enicostemma littorale Blume. Chromatographic separation was performed on silica gel plates with acetonitrile-water, 6.0:4.0 (ν/ν), as mobile phase. Detection and quantitation were performed by densitometry, with a deuterium lamp, at 350 nm. The response to isovitexin reference standard was linear in the concentration range of 100–400 ng per band. The method was validated for precision and accuracy. The relative standard deviation for instrumental precision, intra-assay precision, and intermediate precision was <2%. The percentage recovery was 99.76. This method can be used for routine quality control analysis of the whole-plant powder of E. littorale Blume.

TL;DR: The optimum collection time of showy tick trefoil herbs as plant raw material was the flowering and budding phases of herbs regrowing after mowing, and the recommended optimal exploitation time of a plantation is up to six years.
Abstract: Quantitative and qualitative analyses of flavonoids in showy tick trefoil (Desmodium canadense L., Fabaceae) herbs during various vegetative phases were performed using HPLC techniques at the Department of Medicinal Herbs of the Kaunas Botanical Garden (Vytautas Magnus University). A total of 15 flavonoids of aglycone and glycoside nature was determined including apigenin, apigenin-7-O-glycoside, luteolin, rutin, 2-vicenin, vitexin, isovitexin, vitexin rhamnoside, orientin, homoorientin, quercitrin, quercetin, hyperoside, astragalin, and kaempferol. The maximum amount of identified flavonoids was observed during the flowering phase and was 2.45% in the second vegetative year and 1.28% in the sixth vegetative year, i.e., it decreased constantly during the plant perennial vegetation process. Of these, orientin and homoorientin varied from 45.9 to 38.9% of the total flavonoids; 2-vicenin, from 16.3 to 12.8; vitexin, from 12.7 to 8.6; isovitexin, from 13.0 to 7.7; rutin, from 11.6 to 6.9. The optimum collection time of showy tick trefoil herbs as plant raw material was the flowering and budding phases of herbs regrowing after mowing. The recommended optimal exploitation time of a plantation is up to six years.
