牛羊肉脂肪（4:1）混合物的维生素A活性（通过生物测定表明）已被证明完全是由于维生素A，以及少量的[β]-胡萝卜素。通过反相分割色谱法测定了未皂化部分中维生素A的巨大浓度。
The vitamin A activity (as indicated by bioassay) of a mixture of rendered beef and mutton fats (4:1) has been shown to be due entirely to vitamin A, together with a minor amount of [beta]-carotene. An enormous concentration of the vitamin A in the unsaponifiable portions was effected by means of reversed-phase partition chromatography.
