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。
Effects of physico-chemical factors on the color development of peony anthocyanin solution in vitro were studied. The results showed that the peony anthocyanin solution was stable under the conditions of darkness and room temperature (20 ℃). Under the conditions of natural light, ultraviolet light, blue light, white light, low temperature (4 ℃), oxidant (H2O2), reducing agent Mn2 +, Mg2 +, Zn2 +, Fe2 + and other conditions easily degrade, the color fades; while the red, yellow, high temperature (40 ℃, 60 ℃), Na + on the anthocyanin solution has a certain color enhancement; different p H on Peony flower color Glycosides color effects are not the same. The results provide a basis for the regulation of peony flower color by physical and chemical factors.
