Anthocyanidin extract in methanol showed 3 absorption peaks, at 270, 340 and 520 nm, in the UV-vis spectrum, with bathochromic and hypsochromic shift with methanol+AlCl3 and methanol+AlCl3+HCl, respectively; the ratio of the absorbance at 440 nm to that at 520 nm was 0.29. No fluorescence occurred under UV irradiance, and 5 absorption peaks occurred at 270 nm after HPLC. Five molecular ion peaks occurred on MS: 595, 381, 611, 587 and 571, respectively, and monosaccharides in the extract were identified as rhamuose and glucose on HPLC.

The results showed that the red pigment belonged to anthocyanidin, it was soluble in water, stable against heat treatment, light, acid and sugar concentration, tolerant to reduction, but sensitive to alkaline, oxidation and Fe(superscript 3+). The research also showed that acid medium is favorable for extraction. The pigments have more general stability in acid medium and have high ufility value.
结果表明：该色素为水溶性多酚类花色素，在不同的pH环境下显示不同的颜色；其耐热性、耐光性、耐酸、耐糖、耐还原性较好，但耐氧化性、耐碱性较差；Fe(上标 3+)对色素有破坏性；该色素的提取宜在酸性介质中进行，酸性条件下其综合稳定性较优，有较高的利用价值。
