采用单因素试验与正交试验方法，对乙醇提取岗稔黄酮苷的工艺进行了探讨，研究了岗稔皮与乙醇的质量配比（料液比）、提取时间、提取温度以及乙醇体积分数等因素对岗稔黄酮苷提取得率的影响，结果表明最佳提取工艺条件为料液比1:40、提取时间2.5 h、提取温度80 ℃、乙醇体积分数60%。

[Abstract]
The ethanol extraction of flavonoid glycosides in Rhodomyrtus tomemtosa was discussed by single factor and orthogonal experiments. The influential factors were investigated and the optimal weight ratio of Rhodomyrtus tomemtosa to ethanol, the extraction time, temperature and ethanol concentration were shown to be 1:40, 80 ℃, 60% and 2.5 h, respectively.
