Abstract
The amounts of Zn,Cu,Fe and Mn in Amomum Villosum Lour were determined by FAAS after pretreated at 550℃.The relative standard deviations were between 1.70%—2.70% with the recoveries of 85.5%—99.4%.The calibration curves were linear with good regression coefficients (r0.998).The method was simple,rapid with a satisfactory result.
