利用脏体比、T淋巴细胞数，超氧化歧化酶（SOD），过氧化脂质（LPO）、谷光甘肽过氧化物酶（GSH－Px）测定喂养含不同浓度莲子粉饲料的Wistar大鼠1个月后各项指标，结果发现：胸腺皮质中T淋巴细胞数实验组显著高于对照组，脏体比、SOD、LPO、GSH－Px未发现实验组与对照组之间有明显不同，提示莲子粉有一定增强免疫力的作用。

Antiaging effects or powdered Nelumbo nucifera seed were studied on wistar rats by comparing thcir viscera/body, T lymphocyte, SOD, LPO, GSH-Px between fed animals and control. Results showed that there was obvious increase of T lymphocyte in thorax cortex between fed and control, whereas distinct disparity of other indexes can not be found. These results implied that powdered N.nucifera seed has some functions of enforcing immunity.
