以马尾松针叶软膏为原料，通过化学方法对其中的植醇进行浓缩，然后与２，３，５三甲基氢醌经催化缩合，得到α生育酚浓缩物；再经甲醇提取、酯化及真空蒸馏制得维生素Ｅ浓缩物。主要讨论了合成α生育酚浓缩物的影响因素如原料配比、催化剂种类和用量、反应条件等。分析表明，最终产物中的维生素Ｅ含量高于５０％。 Masson pine needles ointment as raw material, which phytol by chemical methods to concentrate, and then with 2, 3, 5-trimethylhydroquinone by catalytic condensation to give α-tocopherol concentrate; then by methanol extraction, ester Vitrification and vacuum distillation of vitamin E concentrate. The main factors affecting the synthesis of α-tocopherol concentrate such as the ratio of raw materials, the type and amount of catalyst, reaction conditions and so on. Analysis shows that the final product contains more than 50% vitamin E content.
