中药女贞子所致大鼠垂体促肾上腺皮质激素细胞超微结构变化的观察发现，胞浆中的分泌颗粒、核糖体和线粒体的数量显著增加，显示女贞子能提高该细胞合成促肾上腺皮质激素（ＡＣＴＨ）的能力，为中药女贞子补益作用机理的研究提供了形态学依据 Observation of the ultrastructural changes of pituitary adrenocorticotropic hormone in rats induced by Ligustrum lucidum found that the number of secretory granules, ribosomes and mitochondria in the cytoplasm increased significantly, indicating that Ligustrum lucidum can increase the synthesis of adrenocortical cells. The ability of hormones (ACTH) provides a morphological basis for the study of the mechanism of replenishing action of Ligustrum lucidum
