摘要
采用正交实验设计，以美洲商陆浆果总黄酮提取率为考察指标，对影响总黄酮提取率的各类因素进行了研究，初步确定提取美洲商陆浆果中总黄酮较佳的工艺条件，并测定了总黄酮的含量。结果表明，美洲商陆浆果中总黄酮提取的较佳工艺条件为：水浴温度为60℃，乙醇浓度为60％，提取时间为60min，固液比为1：40，总黄酮（以芦丁计）得率为3．12％。
The optimization of extraction method of total favonoids from the fruits of Phytolacca americana L. was obtained by using orthogonal test design, and the content of total flavonoids （rutin as a comparetion） was determined, the results showed that 60℃ of water--bath temperature, 1 ： 40 of ratio of solid to ethanol solution and 60min extraction time were the optimal conditions, under which ratio of total flavonoids （rutin as a comparetion ） in fruits of Phytolacca americana L. was 3.12%.
