乙烯利对红掌佛焰苞花青素和总黄酮含量的影响

为了研究乙烯利对红掌花色的影响及调控，采用高效液相色谱(HPLC)直接进样、梯度洗脱的分析方法，测定5个不同乙烯利浓度处理对红掌佛焰苞的花青素和总黄酮含量的变化。结果表明，红掌 “亚利桑那”花青素主要成分是矢车菊素-3-芸香糖苷。乙烯利处理诱导花青素和总黄酮含量的积累，浓度600 mg/L处理效果最佳，花青素和总黄酮含量提前在展开期出现最高峰，而对照在盛花期才出现高峰，峰值为3496.7581 μg/g和5088.3177 μg/g，比对照峰值分别高出56.9%和59.0%。

The Effect of Ethephon on the Content of Anthocyanin and Flavonoids in Anthurium andraeanum Spathe

In order to study the effect and the control of ethylene on the coloration of Anthurium andraeanum Spathe, the content of anthoeyanin and total flavonoid was detected at 5 different concentrations of ethephon treatment in Anthuriurn andraeanurn Spathe by means of high performance liquid chromatography （HPLC） with direct injection and gradual elution. The result showed that the anthocyanin of Anthurium andraeanurn ＇Arizona＇ was mainly composition of cyanidin-3-o-rutinoside chloride. The content of anthocyanin and total flavonoids was accumulated by ethephon induced and the concentration of 600 mg/L treatment was the optimal. The peak of the content of anthocyanins and total flavonoids was appeared in the expand period while the peak of control was appeared in flowering stage by the peaks were 3496.7581 μg/g and 5088.3177 μg/g, which was higher than the control peak by 56.9% and 59.0% respectively.
