【现代研究】 1．化学成分：肉苁蓉脂溶性成分经气质联用鉴定出6-甲基吲哚，3-甲基-3乙基己烷。从肉苁蓉中得到水溶性的N，N-二甲基甘氨酸甲脂和甜菜碱等。

2．药理作用：肉苁蓉水提液小鼠灌胃，能显著增加脾脏和胸腺重量，增强腹腔巨噬细胞吞噬能力，提高淋巴细胞转化率和迟发性超敏反应指数。肉苁蓉对阳虚和阴虚动物的肝脾核酸含量下降和升高有调整作用。有激活肾上腺、释放皮质激素的作用，可增强下丘脑-垂体-卵巢的促黄体功能，提高垂体对LRH的反应性及卵巢对LH的反应性，而不影响自然生殖周期的内分泌平衡。肉苁蓉乙醇提取物在体外温育体系中能显著抑制大鼠脑、肝、心、肾、睾丸组织匀浆过氧化脂质的生成，并呈良好的量效关系。
