Acylated anthocyanins from flowers of Begonia

Anthocyanins from red flowers of Camellia cultivar ‘Dalicha’

“…2). Except pigments 1-6, known pigments, cyanidin 3-O-(2-O-b-xylopyranosyl)-b-glucopyranoside (Cy3GX) (Robinson and Robinson, 1931;Cabrita and Andersen, 1999;Du et al, 2004), cyanidin 3-O-(2-O-b-xylopyranosyl-6-O-(Z)-p-coumaroyl)-b-glucopyranoside (Cy3GXZ) (Inami et al, 1996;Nakatani et al, 1994) (Chirol and Jay, 1995), cyanidin 3,5-di-O-b-glucopyranoside (Cy3G5G) (Mas et al, 2000) and (Goto et al, 1978) were detected (Fig. 2).…”

“…Furthermore, the 13 C NMR spectrum established that there are four additional quaternary carbons at d 127.7, 146.8, 149.7 and 169.1 (COO). Taking into account all of these spectroscopic data, pigment 4 consists of pigment 1 coupled with an E-caffeoyl group(Chirol and Jay, 1995). The E-caffeoyl group is concluded to be attached to the 6-position of the galactose moiety due to the downfield shift observed in the 1 H NMR spectrum at d 4.56 and 4.31 (each 1H, dd).…”

Convenient Methods for the Extraction and Discrimination of Water-Soluble Plant Pigments

“…For the clarification, previously well identified and reported anthocyanins and betacyanins were newly selected and extracted from plant tissues and applied to gel electrophoresis as references. The anthocyanin pigments were from red leaves of maple (Acer palmatum) [8], and poinsettia (Euphorbia pulcherrima) [24], and flowers of begonia (Begonia semperflorens) [9], touch-me-not (Impatiens balsamina) [12], rose (Rosa hybrida) [22], geranium (Pelargonium × hortorum) [23], morning glory (Pharbitis nil) [10], and balloon (Platycodon grandiflorum) [11]. On the other hand, the betacyanin pigments were from root of red beet (Beta vulgaris) [7], flowers of cockscomb (Celosia cristata) [13] and four o'clock (Mirabilis jalapa) [14], fruit of pokeweed (Phytolacca americana) [15], and red leaf of goosefoot …”

Flavonoids and Antimicrobial Properties of Begonia fischeri var. palustris in vitro Plantlets

“…In leaves and flowers, luteolin, luteolin 7-О-glucoside (cynaroside), quercetin, rutin, quercitrin, isoquercitrin, quercetin 3-О-xyloside, kaempferol 3-O-glucoside (astragalin), kaempferol rutinoside, kaempferol 3-methyl ether (isokaempferide) and its 7-О-glucoside, quercetin 3-methyl ether and its 7-О-glucoside, quercetin 3, 7, 3´-trimethyl ether and gossypetin 3,7,8,3´-tetramethyl ether, glycosyl flavones (vitexin, isovitexin and orientin) were found. In anthocyanin composition, glycosides of cyanidin, pelargonidin and peonidin were detected (Chirol and Jay, 1995;Harborne and Williams, 2001;Saffidine et al, 2017). There are very few reports concerning the concentrations of flavonoids in in vitro derived plants (Murugan et al, 2016) and the chemical content of B. fischeri var.…”
