Anthocyanins from red flowers of Camellia cultivar 'Dalicha'.
Five anthocyanins, cyanidin 3-O-(2-O-beta-xylopyranosyl-6-O-(Z)-p-coumaroyl)-beta-galactopyranoside (2), cyanidin 3-O-(2-O-beta-xylopyranosyl-6-O-(E)-p-coumaroyl)-beta-galactopyranoside (3), cyanidin 3-O-(2-O-beta-xylopyranosyl-6-O-(E)-caffeoyl)-beta-galactopyranoside (4), cyanidin 3-O-(2-O-beta-xylopyranosyl-6-O-acetyl)-beta-galactopyranoside (5), and cyanidin 3-O-(2-O-beta-xylopyranosyl-6-O-a...
متن کاملAcylated Anthocyanins from Flowers of Cineraria, Senecio cruentus, Red Cultivar
Cinerarin, the anthocyanin isolated from the blue flowers of garden cineraria, S. cruentus by Yoshitama et al. [1, 2], was identified as dicaffeylated delphinidin 3,7,3'-triglucoside on the basis of the chemical evidences and its extraordinary sta bility in a neutral aqueous solution was also point ed out. Goto et al. [3] established its complete structure as malonyltricaffeyl delphinidin-tet...
متن کاملAnthocyanins from red flowers of Camellia reticulata LINDL.
Ten anthocyanins, cyanidin 3-sambubioside, 3-glucoside and their acylated derivatives, cyanidin 3-lathyroside and cyanidin 3-galactoside, were isolated from red flowers of Camellia reticulata. Their structures were determined on the basis of spectroscopic analyses, and the chemotaxonomic distribution of the accumulated anthocyanins in the petals of wild Camellia reticulata and C. pitardii var. ...
متن کاملTwo new chalcones from the flowers of Clerodendrum inerme.
Two new chalcones, 3-hydroxy-3',4'-dimethoxychalcone (1) and 3,2'-dihydroxy-3',4'-dimethoxychalcone (2), were isolated from the flowers of Clerodendrum inerme (L.) Gaertn together with two known flavones, 7-O-methylwogonin (3) and eucalyptin (4). The structures of the new compounds 1 and 2 have been established by extensive 2D-NMR and ESI-TOFMS studies.
متن کاملGeneration of blue chrysanthemums by anthocyanin B-ring hydroxylation and glucosylation and its coloration mechanism
Various colored cultivars of ornamental flowers have been bred by hybridization and mutation breeding; however, the generation of blue flowers for major cut flower plants, such as roses, chrysanthemums, and carnations, has not been achieved by conventional breeding or genetic engineering. Most blue-hued flowers contain delphinidin-based anthocyanins; therefore, delphinidin-producing carnation, ...
