TL;DR: Four known compounds including three phenolics, isovitexin, astragalin, and methyl gallate 3-O-β-D-(6'-O-galloyl)-glucopyranoside, and the terpene glucoside icariside B 2 have been isolated from the aerial parts of Circaea lutetiana ssp. canadensis.
Abstract: A new alcohol glycoside, 1-octyl α-D-arabinofuranosyl-(1→6)-β-D-glucopyranoside (1), four known compounds including three phenolics, isovitexin, astragalin, and methyl gallate 3-O-β-D-(6'-O-galloyl)-glucopyranoside (2), and the terpene glucoside icariside B 2 (3) have been isolated from the aerial parts of Circaea lutetiana ssp. canadensis.

TL;DR: Swertisin, C22H22O10, m.p. 243°(decomp.), was isolated in a pure state from the whole herb of Swertia japonica MAKINO (Gentianaceae), and identified as 6-C-β-D-glucopyranosylgenkwanin, which was found that they were interconvertible into each other, reminiscent of the interrelationship between vitexin and isovitex
Abstract: Swertisin, C22H22O10, m.p. 243°(decomp.), was isolated in a pure state from the whole herb of Swertia japonica MAKINO (Gentianaceae), and identified as 6-C-β-D-glucopyranosylgenkwanin. Isoswertisin, C22H22O10, m.p. 295°(decomp.), was obtained by the acid-treatment of swertisin, and formulated as 8-C-β-D-glucopyransylgenkwanin. At the same time, it was found that they were interconvertible into each other, reminiscent of the interrelationship between vitexin and isovitexin.

TL;DR: Seven compounds were isolated from ethyl acetate and n-butanol extract and identified as 5-hydroxyl-7, 3', 4'-trimethoxy flavone, luteolin, isoorientin, quercetin, isovitexin, and 8-C glucosylprunetin.
Abstract: OBJECTIVE To investigate the chemical constituents of Patrinia villosa. METHOD The chemical constituents were isolated by silica gel column chromatography and semi-preparative high-performance liquid chromatography, and identified by physicochemical properties and spectral analysis (MS, 1H-NMR and 13C-NMR). RESULT Seven compounds were isolated from ethyl acetate and n-butanol extract and identified as: 5-hydroxyl-7, 3', 4'-trimethoxy flavone (I), 5-hydroxyl-7, 4'-dimethoxy flavone (II), luteolin (III), quercetin (IV), isoorientin (V), isovitexin (VI) and 8-C glucosylprunetin (VII). CONCLUSION Compounds I , II, III, V, VI and VIII were obtained from the plant of genus Patrinia for the first time, compound IV was separated from P. villosa for the first time.

TL;DR: The phenylpropanoid profiles of the first and third leaf of barley seedlings in Scarlett and four members of the S42IL-population were obtained by LC-MS and revealed a change in the glycosylation pattern of the flavone-6-C-glucoside isovitexin in the elite cultivar Scarlett.
