The result indicates that the best method for extracting β-carotene is to saponify the test specimen one hour with 4% NaOH methyl alcohol solution in 60-70'c and then to separate with 3:7 acetone-benzine component solvent as extraction solvent, MgO as the absorbent, the acetone-benzine as the eluent. Extracted solvent has been determined in the color dish condition (1cm) by ultraviolet spectrophotometer at 447 nm. The result shows that the β-carotene in carrotis 0.134 mgg^(-1), 0.0863mgg^(-1) in red pepper and 0.0426 mgg^(-1) in spinach.

Digestion conditions, working conditions of atomic fluorescence spectrometer and conditions of hydride generation reaction were studied. Methods for the reduction from Se to Se by using boiling water bath and UV were compared. The amount of sulfamic acid for the elimination of the interference of nitrogen oxides was also investigated.

探讨了消解条件、原子荧光光度计工作条件及氢化物发生反应条件，对比沸水浴加热和紫外光加热2种将Se还原为Se的方法，研究氨基磺酸消除氮氧化物干扰的最佳条件。

N-substituded thioacridones with five different structures were synthesized via a route involving Ull-man reaction, cyclization, N-alkylation and sulfurization. The structures of each thioacridone were identified with IR and MS. The results from UV-spectrophotometry show that the five N-alkythioacridones all have stronger absorption in the visible light region.
