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.

结果表明，比较优先的β-胡萝卜素提取方法是：试样用4% NaOH甲醇溶液在60℃~70℃皂化1h，用3：7的丙酮－石油醚混合溶剂提取，以Mgo为吸附剂，丙酮－石油醚为洗脱剂分离，提取液用紫外分光光度计在波长447nm，1cm比色皿条件下测定，得出蔬菜中β-胡萝卜素含量：胡萝卜为0.134mgg^(-1)，红椒为0.0863mgg^(-1)，菠菜为0.426mgg^(-1)。
