The stability of protein and phenolic measures in excised foliage from two oak species was measured under conditions that simulated the handling and treatment of foliage during insect rearing trials. Excised foliage kept hydrated under refrigeration or insect-rearing conditions maintained stable levels of protein content, proanthocyanidins, gallotannins, total phenolics, and protein-binding capacity for up to 48 hr following field sampling. Measures of protein content, total phenolics, protein-binding capacity, and proanthocyanidins were significantly greater 48-72 hr after field sampling, followed by declines to near field levels within 120 hr.
两种橡树的离体叶片在模拟昆虫饲养试验中叶片处理和操作条件下，测定了蛋白质和酚类物质的稳定性。离体叶片冷藏或在昆虫饲养条件下保持水分，其蛋白质含量、原花青素、鞣花单宁、总酚和蛋白质结合能力在野外采样后 48 小时内保持稳定水平。在野外采样后 48-72 小时，蛋白质含量、总酚、蛋白质结合能力和原花青素的测定值显著更高，随后在 120 小时内降至接近野外水平。
