Abstract: Solvent extraction, ultrasonic-assisted extraction and microwave-assisted extraction of polyphenols from Canarium album (Lour.) Rauesch. were studied, and extraction effects of three methods were also compared. The results indicated that 60%-70% aqueous acetone was the preferred solvent for polyphenol extraction, the optimum condition of solvent extraction was as follows: leaching time 1 h, temperature 20-30℃, ratio of material to solvent 1:20, the optimal power and action time for ultrasonic extraction were 80 W and 25 min, while that for microwave extraction were 280 W and 5 s. The polyphenol yields of three methods were 17.1%, 19.3% and 20.3% respectively. As compared with solvent extraction method, ultrasonic-assisted and microwave-assisted methods were more rapid and efficient for extracting polyphenols from C. album, and their UV spectrograms and HPLC chromatograms of polyphenol extracts were identical.
