| Abstract: | OBJECTIVE： To determine the content of selenium in Verbena officinalis .METHODS： The content of selenium in Verbena officinalis was determined by UV spectrophotometry with o- phenylenediamine as developer under a detection wavelength of 335 nm. RESULTS： The linear range of selenium was 0-0.10μg·mL^-1（r=0. 999 3） with an average recovery of 99.78% （RSD = 0.29%, n = 9） ~ CONCLUSION： The method was proved to be simple, sensitive and accurate, and applicable for the determination of trace element selenium in Verbena officinalis. |
