Extracting Technology of Luteoloside from Callicarpa formosana Rolfe

Objective To study the extracting technology of luteoloside from Callicarpa formosana Rolfe. Methods The optimum extrac- tion process was screened with the orthogonal design, and the influence of factors such as the ethanol concentration, ethanol dosage and extracting time were investigated for optimizing the extracting condition. The HPLC method was adopted to determine the luteoloside content for comparing the extraction effect. Results The optimum extraction process was adding 10 times the amount of 70% ethanol and extracting for 3 h. Conclusion This technology is stable, feasible and suitable for industrial production.
