Study on extraction process of total flavones of Pollen Typhae / 中成药

ABSTRACT

Objective: To study the extraction process of the total flavones of Pollen Typhae ( Typha angustifolia L.). Methods: The optimum extraction process was selected with the orthogonal design. The content of total flavones was determined by UV spectrophotometry. Results: The significant effects of alcohol concentration, extraction time and extraction times on the extraction of total flavones were discovered. Conclusion: The optimum extraction process was as follows Pollen Typhae was extracted with 70% alcohol for 3 times, with the solvent volume 8, 6, 6 times amount and extraction time 60, 60, 30 minutes in turn.
