摘　　要：以70%的乙醇为溶剂从商陆果实中提取色素,研究料液比、提取温度、提取时间对色素提取效果的影响.选择不同的媒染剂,采用不同的媒染方式,将从商陆提取液中得到的色素粉末配制成染液,对真丝织物进行染色,考察不同条件下染色真丝织物的色牢度.结果表明,较佳的提取工艺为:料液比1∶20,提取温度50℃,浸提45 min.所用媒染剂种类和媒染方式不同,染色织物的颜色强度和色相都不同.与直接染色织物相比,媒染可提高染色织物的耐皂洗牢度.Colorant from the fruit of phytolacca was extracted with 70% ethanol as solvent. The influenc- es of solid-liquid ratio, extraction temperature and extraction time on the extraction effect were studied. Choosing different kinds of mordants and different mordant dyeing methods, the phytolacca dyeing solution was prepared with the colorant powder obtained from the extracted solution for silk fabric dyeing. The color fastness of dyed silk fabric in different dyeing conditions was investigated. The results showed that better ex- traction conditions for phytolacca berry colorant were： traction time 45 min. The color depth and hue of dyed dant dyeing method. Compared with the direct dyed fastness of dyed fabric. solid-liquid ratio 1：20, extraction temperature 50 ℃, ex- fabric changed with different types of mordant and morsilk fabric, mordant dyeing could improve the washing
