采用纸层析法制取山葡萄色素中各纯组分。以浓盐酸：甲酸:水:24．9:23.7:51．4（V／V）为展开剂。分离出两个独立的非常明显的色谱带。根据0.1％盐酸甲醇液中显色，紫外-可见吸收光谱测定，与Alcl3反应，糖组分鉴定，色素的部分及完全水解，A44／A-max比值等综合研究结果推断，山葡萄色素两组分分别为芍药色素-3-葡萄糖苷（Pn-3-glu）和矢车菊素-3-葡萄糖苷（Cy-3-glu）。
The chromatographic method was used to prepare the pure components of the mountain grape pigment. Concentrated hydrochloric acid: formic acid: water: 24.9: 23.7: 51.4 (V / V) as the developing agent. Two separate, very distinct chromatographic bands are separated. According to the results of the comprehensive study of the color, UV-visible absorption spectroscopy, reaction with AlCl3, the identification of sugar components, the partial and complete hydrolysis of pigment and the ratio of A44 / A-max in 0.1% hydrochloric acid methanol solution, They were Pn-3-glu and Cy-3-glu, respectively.
