LI Xue-yan,CHEN Hai-qiang,DING Ting-ting,CHEN Rui-ying (Zhongshan College,UEST of China,Zhongshan 528402,Guangdong,China)  
Allium Tuberosum pigment material as raw material extraction and use of UV-visible spectrum of material for the identification of carotenoids pigments,a single-factor test and experiment with orthogonal contrast. The results showed:for extractingthe carotenoids pigments of Allium Tuberosum the optimum conditions were perfomed bypetroleumether:temperature of 30 ℃,feed solvent = 1∶4 (g/mL),extracting 1 times with 90 min per time.The study provides reference for further using of Allium Tuberosum.
