| 摘 要： | 经热处理以钝化脂肪氧化酶，进行了小麦胚芽提取天然生育酚的实验和研究。用９５％的乙醇水溶液浸出小麦胚芽，浸出液经脱溶、浓缩和精制处理，得到天然生育酚浓缩物，其生育酚总含量为２１５３．２ｍｇ／１００ｇ；用石油醚浸出小麦胚芽得到毛油，毛油经精炼得精炼胚芽油，在高真空和高温下脱臭得脱臭馏出物，脱臭馏出物经一系列精制处理得到天然生育酚浓缩物，其生育酚总含量为２０６７．６ｍｇ／１００ｇ。

| Abstract: | Extraction of germ is reported. After heat treatment of wheat germ for inactivating lipoxidase,wheat germ was extracted by aqueous ethanol(95%w/w).The extractmixture was desolvented,concentrated and purified by a series of treatment.Thus the natural tocopherol concentrate was obtained.Total tocopherol content of it was up to2153.2mg/100g;In another extraction method, crude oil was extracted from wheat germby petroleum ether,then refined.The refined oil was deodorized under high vacuum andhigh temperature.Then the natural tocopherol concentrate was obtained from deodorized distillate after a series of treatment.Total tocopherol content of it was up to 2067.6mg/100g. |
