摘要
以两种不同颜色的石斛兰为材料,通过特征显色反应和紫外-可见光谱扫描对其花瓣中的色素成分进行了初步分析和鉴定。结果表明,红色石斛兰花瓣主要为类黄酮和花色素苷,而白色石斛兰只含有类黄酮类色素。该项研究为石斛兰花色素成分的进一步分离和鉴定等工作奠定了基础,同时也为石斛兰花色的分子育种提供帮助。
Petal pigment composition of Dendrobium was primarily investigated and identified by using of specific color reactions and UV-visible spectra.The results indicated that flower pigments of red-purple Dendrobium consist of flavonoids and anthocyanins..The pigments of white flower consist of flavonoids only.This paper provides a reference for the identification of molecular structure of flower pigments and the breeding of flower color of Dendrobium.
