摘　　要：以桑果、杨梅为材料,通过特征颜色反应和紫外-可见光谱分析对其色素成分进行了研究。结果表明:桑果、杨梅色素均属于黄酮类化合物,不含查耳酮、橙酮、儿茶素、黄酮醇等,可能含黄酮、二氢黄酮、二氢黄酮醇、花色素及其苷等。桑果、杨梅色素的红色是由于其花色素及其苷,且其红色的程度与其花色苷含量相关。The pigment components of Morus alba and Myrica rubra fruits were preliminarily stud- ied by means of specific color reactions and ultraviolet-visible spectroanalysis. The results indicated that pigments of both fruits were flavonoids, excluding chalcone, aurone, catechin and flavonol but probably including flavone, flavanone, flavanonol, anthocyanidin and anthocyanin. The red color of both fruits~ pigments derived from anthocyanidin and anthocyanin, and the red chromaticity was re- lated to the anthocyanin content.
