| Abstract: | To establish a method for determination of selenium in Gastrodia Powder, atomic fluorescence spectrometer was applied to determine selenium under optimized conditions in Gastrodia, microwave digestion was employed in sample pretreatment. The results show that the precision and recovery of Selenium in gastrodia are between 93.1% - 103.5% and between 4. 5%. It indicates that the methods can be applied to determine selenium in Gastrodia Powder with simple, fast and accurate. |
