摘要
研究迎春花黄色素的提取工艺条件和基本性质。结果表明,丙酮提取效果最好,较优提取工艺条件是:1g干花粉加入40mlpH6的丙酮溶液,60℃1.0h。该色素对弱酸、弱碱、还原剂、金属离子等较稳定,耐热性较强,但对氧化剂和强光照射不稳定。
This paper studied the extraction method, basic properties and stability of the yellow pigment obtained from Jasmine nudiflorum L. The effects of pH value, metal ions, oxidants, temperature and light on the stability of the yellow pigment were studied. The optimum technology of extraction is that the sample： solvent （1：40）, selecting acetone （pH=6.0）, heated at 60℃ for 1 .0h.
