摘要：

This study investigated subcritical water extraction of trans-resveratrol and its glycosylated form, trans-piceid, from barks of Shorea roxburghii G. Don. The effects of extraction temperature (100-190 degrees C) and water flow rate (2-4 mL/min) at the pressure of 10 MPa were determined on the amounts of compounds extracted. The amount of trans-resveratrol and trans-piceid in the extracts increased with increasing temperature and flow rate, although the increase in flow rate from 3 to 4 mL/min had no significant effect on the extraction yield. Thus the flow rate of 3 mL/min was taken to be the most suitable. At suitable condition (190 degrees C, 3 mL/min), the amount of trans-resveratrol and trans-piceid were 23.18 and 350.28 mu g/g dry weight, respectively. With equal extraction duration, the amount of trans-resveratrol and trans-piceid compound obtained from extraction using 190 degrees C subcritical water were higher than those from extractions with ambient water and 80% ethanol.
