摘　　要：以小苍兰(Freesia refracta)16个不同花色品种及后代为试验材料,对花瓣色素用特征显色反应和紫外-可见光谱扫描,分析其色素的成分和花色素苷的稳定性。结果表明,小苍兰花色的色素属于类黄酮化合物,含黄酮和花色素苷类物质,可能含有异黄酮,不含黄酮醇、二氢黄酮、二氢黄酮醇、查耳酮和橙酮,其中黄色系品种及后代还含有类胡萝卜素。避光下小苍兰花色素苷的稳定性要强于光照;温度对花瓣色素的稳定性有一定的影响。The component and stability of anthocyanidins in petals of sixteen Freesia refracta cultivars were analyzed by the specific color reactions and UV-visible spectrum. The results showed that the petal anthocyanidins in all cultivars belonged to flavonoids, including flavones, anthocyanins substance, and might contain isoflavones, but no flavonols, flavanones, flavanonols, chalcones and aurones. The cultivar of yellow petals lines also contained carotenoids. The anthocyanins under dark were more stable than that under light. And there were some effects of temperature on the stability of petal anthocyanidins.
