中文摘要：

研究了理化因子对芍药花色苷溶液在体外呈色的影响。结果表明：芍药花色苷溶液在黑暗、室温（20℃）等条件下表现稳定;在自然光、紫外光、蓝光、白光、低温（4℃）、氧化剂（H2O2）、还原剂（Na2SO3）、Cu2＋、Mn2＋、Mg2＋、Zn2＋、Fe2＋等条件下易于降解,颜色变淡;而红光、黄光、高温（40℃、60℃）、Na＋对花色苷溶液具有一定的增色作用;不同p H对芍药花色苷溶液呈色影响并不一致。研究结果可为通过理化因子来调控芍药花色奠定基础。

英文摘要：

The effect of physical and chemical factors on the coloring of anthocyanins in herbaceous peony（ Paeonia lactiflora Pall.） was investigated in this paper. The results showed that darkness and room temperature（ 20 ℃） had no effect on the stability of anthocyanins. Furthermore,natural light,ultraviolet light,blue light,white light,low temperature（ 4 ℃）,oxidant（ H2O2）,reductant（ Na2SO3）,Cu2＋,Mn2＋,Mg2＋,Zn2＋and Fe2＋promoted the degradation of anthocyanins. In addition,red light,yellow light,high temperature（ 40 ℃ and 60 ℃） and Na＋had color enhancing effect on anthocyanins,and different p H value had different color effect on anthocyanins. These results would lay a foundation for regulating P. lactiflora flower color by physical and chemical factors.
