A dietary component that initiates both the tranisition from parthenogenetic to sexual reproduction and the production of lateral, posterodorsal, and posterior outgrowths of the body wall of females was isolated from the neutral lipids of dried grass and identified as (alpha)-tocopherol. The smallest concentrations eliciting both responses were below 100 nanograms per milliliter. Relative activities of (alpha)-, beta3-, and (gamma)-tocopherol and (alpha)-tocopheryl-quinone were roughly 100 : 100 : 20 : 0.4. The synthetic antioxidants tested were without activity.
从干草的中性脂质中分离出一种膳食成分，它既能引发从孤雌生殖到有性生殖的转变，又能促使雌性动物体壁产生侧向、后背部和后部的生长物，该成分被鉴定为α-生育酚。引发这两种反应的最小浓度低于每毫升100纳克。α-、β3-和γ-生育酚以及α-生育酚醌的相对活性约为100 : 100 : 20 : 0.4。所测试的合成抗氧化剂没有活性。
