摘要
以钝裂银莲花(Anemone obtusiloba)的萼片为提取材料,选取料液质量浓度、pH、提取时间、提取温度4个因素,以钝裂银莲花花色素提取液的吸光值为响应面,对钝裂银莲花花色素的提取条件进行优化,用四舍五入法确定了钝裂银莲花花色素提取的最佳工艺为:料液质量浓度70g·mL^(-1),pH 3.8,提取温度61℃,提取时间87min,在此条件下,钝裂银莲花花色素提取液的吸光值可达最佳,为0.154 5。
In this study, we used the sepals of Anemone obtusiloba as experimental material for extraction of anthocyanidin using response surface methodology. Four factors were selected in this experiment., the material liquid mass concentration, pH, extraction time, and extraction temperature. We selected the light absorption value of the anthocyanidin of A. obtusiloba as a response surface to optimize the extraction conditions of anthocyanidin. Our results confirmed that the most efficient extraction of anthocyanidin was achieved under the following conditions： a material liquid mass concentration of 70 g ·mL-1 , an extraction temperature of 61 ℃, an extraction time of 87 rain, and pH 3.8. Under these conditions, we conclude that the best light absorption value of A. obtusiloba is 0.154 5.
