摘要

To reveal the violet blue color expression in the tall bearded iris cultivar 'Victoria Falls', colorimetric value, absorption spectra, quantitative analysis of phenolic compounds, and pH value were measured using falls and standards of the flowers. Higher lightness and lower chroma values were shown in standards than those of falls. Absorption spectral curves of the intact falls and standards are essentially the same, i.e. λmax at 578.9 nm and 580.2 nm, respectively. Copig-ment index [total C-glycosylflavone (TF) contents per total anthocyanin (TA) contents] in each part were calculated as 9.4 to 12.8 from the quantitative analysis. Total C-glycosylxanthone (TX) contents per TA value were also calculated as 3.1 to 4.1, respectively. Based on these results, in vitro examination using isolated anthocyanin, violanin, C-glycosylfiavone, swertisin 2″-O-arabino-side, and C-glycosylxanthone, mangiferin, was performed. Degradation rate of the optical density of these solutions was also measured. Bathochromic shift of 34.3 and 37.8nm was observed by the addition of 0.3 and 0.9 mM swertisin 2″-O-arabinoside to 0.1 mM violanin solution. Bathochromic shift of Amax 5.2nm by the addition of 0.3mM mangiferin to violanin solution was observed. Furthermore, we were reappeared the absorption spectral curve of the intact falls by the addition of 0.9mM swertisin 2″-O-arabinoside and 0.3 mM mangiferin to 0.1 mM violanin solution, suggesting that the violet blue color expression and stability of the tall bearded iris cultivar is expressed by mixture of these compounds.
