Abstract:
AIM: To investigate the influence of microwave-assisted extraction on flavone contents of Pollen Tyhae micropowder. METHODS: Ultraviolet spectrophotometer and HPLC were applied to analyze Pollen Tyhae micropowder, total flavon and isorhamnetin-3-O-neohespridoside were adopted as the marker, respectively. RESULTS: Appropriate conditions of microwave-assisted extraction included: extraction time of 8min, ethanol concentration of 70%, Solid/liquid ratio of 1∶18 (g?mL -1) and the power of microwave oven of 540w. CONCLUSION: Compared with normal reflux method, microwave-assisted extraction of Pollen Typhae micropowder is more useful and can improve the extraction rate the reduce the extracting time.
