摘　　要：采用高效液相色谱法（HPLC）,对3个牡丹品种花瓣的花青素和黄酮组成及含量进行测定,以比较四种不同处理方法对牡丹花瓣色素组成及含量的影响。最后采用紫外-可见分光光度法进一步研究了干燥箱不同干燥温度对色素的影响。实验结果表明：4种方法的保存效果差别明显,其中以干燥箱干燥后密封避光保存法对色素影响最小,且该方法成本低、运输方便、操作简单,为保存牡丹花瓣的最优方法。建议干燥温度范围为60-80℃。In this paper,the effect of four different preservation methods on the pigment in tree peony petal were explored by determining the component and content of flavonoids and anthocyanins using high performance liquid chromatography（ HPLC） with three tree peony cultivars. UV- visible spectra of total anthocyanins（ TA） and total flavonols（ TF） were used to further examine the effect of different drying temperatures on pigment. The results showed that there were noteworthy differences among the four methods in terms of preserving pigment.Among the four methods,the hot- air- drying method was regarded as the optimal method to preserve tree peony petal due to its advantages including minimum impact on pigments,low cost,easy transportation and easy operation.Finally,it was suggested that the drying temperature should range from 60 ℃ to 80 ℃.
