生育酚和生育三烯酚。采用皂化法和正相液相色谱法测定了果蔬生品和加工品中的维生素C含量。所有样本都是在当地获得的，或者是作为美国农业部国家食品和营养分析计划（NFNAP）的一部分收集的。所有的水果、蔬菜和加工产品都是从美国农业部的重点食品清单中挑选出来的。这项研究包括32种生的和加工过的水果，22种生的蔬菜，各种番茄制品，烤豆，煮土豆，冷冻花椰菜和冷冻绿色豌豆。α-生育酚（α-T）在所有产品中都可检测到，并且通常代表以最高量存在的维生素E形式。仅在哈密瓜、无花果、红树莓、花椰菜、蘑菇、莴苣和绿色豌豆中γ-生育酚（γ-T）高于α-T。α-和γ-生育三烯酚（α-和γ-T3）在几种水果和蔬菜中是可测量的，但水平通常低于0.1 mg/100 g。(c)2005年由Elsevier Inc.出版
Tocopherol and tocotrienol. contents of raw fruits and vegetables and processed products were determined by saponification and normal phase liquid chromatography. All samples were either locally obtained or collected as part of the US Department of Agriculture's National Food and Nutrient Analysis Program (NFNAP). All fruits, vegetables and processed products were selected from the USDA Key Foods list. The study included 32 raw and processed fruits, 22 raw vegetables, various tomato products, baked beans, cooked potatoes, frozen broccoli and frozen green peas. alpha-Tocopherol (alpha-T) was detectable in all products and usually represented the vitamin E form present in highest quantity. gamma-Tocopherol (gamma-T) was higher than alpha-T only in cantaloupes, figs, red raspberries, cauliflower, button mushrooms, lettuce, and green peas. alpha- and gamma-Tocotrienols (alpha- and gamma-T3) were measurable in several fruit and vegetables but at levels usually less than 0.1 mg/100 g.
