Abstract: This study aimed to investigate the effect of water extraction process on the main active components of Cllicarpa nudiflora. An orthogonal experiment was designed to study optimal water extraction technology of Cllicarpa nudiflora based on the investigating the solid??liquid ratio and the number of decoction times on the contents of luteolin and verbascoside. The results showed that there was no significant difference in the effect of solid ?liquid ratio on the contents of luteolin and verbascoside（P>0.05），but the content of luteolin and verbascoside was the best when the water addition ratio was 14 times. There was a significant difference in the effect of the number of decoction times（P< 0.05），and the contents of verbascoside and luteolin in the extract was the highest when the number of decoctions was 3 times. The orthogonal test results showed that the extraction times had the greatest influence on the contents of multein and luteolin，followed by the extraction time，the ratio of solid to liquid had the least influence，and the optimal water extraction process was 14 times of water for 3 times，and 1 hour each.

摘要： 本文主要进行水提工艺对裸花紫珠主要有效成分的影响研究，在考察料液比、煎煮 次数对木犀草苷和毛蕊花糖苷含量影响的基础上，设计正交试验，研究裸花紫珠最佳水提工 艺。试验结果表明，料液比对木犀草苷和毛蕊花糖苷含量无显著影响（P>0.05）；煎煮次数对木 犀草苷和毛蕊花糖苷含量的影响显著（P<0.05），其中煎煮次数为3次时提取液中毛蕊花糖苷和 木犀草苷的含量最高。正交试验结果表明，提取次数对毛蕊花糖苷和木犀草苷含量的影响最 大，其次是提取时间，料液比对其的影响最小，最佳水提工艺为14倍水提取3次，每次1小时。
