TL;DR: Compounds (I and II) which inhibited lipid peroxides formation (in in vitro experiments) were isolated together with various flavonoids from the roots of Scutellaria baicalensis GEORGI.
Abstract: Compounds (I and II) which inhibited lipid peroxides formation (in in vitro experiments) were isolated together with various flavonoids from the roots of Scutellaria baicalensis GEORGI. From the analytical and physical data, compounds I and II were identified as (2S)-2', 5, 6', 7-tetrahydroxy-flavanone and (2R, 3R)-2', 3, 5, 6', 7-pentahydroxy-flavanone, respectively. Compound II inhibited the lipid peroxide formation by Fe2+ and ascorbic acid. Compounds I and II inhibited the lipid peroxide formation induced by adenosine diphosphate and reduced nicotinamide adenine dinucleotide phosphate in rat liver homogenate.

TL;DR: From the bark of Brackenridgea zanguebarica, four novel biflavonoids have been identified as mentioned in this paper, which include a chalcone-benzofuran dimer, its dihydrobenz-ofuran derivative, a known dimeric flavanone, and a CHC-flavanone dimer.

TL;DR: A method has been developed for the individual quantitative determination in grapefruit juice and juice sacs of the bitter flavanone glycosides naringin, neohesperidin, and poncirin and of their tasteless isomers, naringenin-7β-rutinoside, hesperid in, and isosakuranetin- 7β- rutinosides.

TL;DR: In this paper, the separation of enantiomers of flavanone and 5 chiral derivatives was studied on two experimental polysaccharide-based chiral columns by high-performance liquid chromatography with methanol, ethanol, acetonitrile, n-hexane/ethanol and nhexane 2-propanol as mobile phases with emphasis on the effect of analyte and chiral selector structure.
Abstract: The separation of enantiomers of flavanone and 5 chiral flavanone derivatives was studied on two experimental polysaccharide-based chiral columns by high-performance liquid chromatography with methanol, ethanol, acetonitrile, n-hexane/ethanol and n-hexane/2-propanol as mobile phases with emphasis on the effect of analyte and chiral selector structure on separation parameters. Since chiral selectors were covalently immobilized onto the surface of silica, it was possible to use a wider variety of mobile phases in order to optimize enantioseparations. Together with the backbone of the polysaccharide, the significant role of substituents in the phenyl moiety of chiral selectors, as well as the structure of the analyte was observed on retention and enantioselectivity.
