东革阿里叶提取物
除了自 1998 年以来一直未变的东革阿里 1:200 根提取物外，我们还生产东革阿里叶提取物，并且是全球唯一一家商业化生产的公司。
与根部相比，叶片中的优可马酮含量是根部的 20 倍。每毫升叶片中含有超过 6 微克的东革阿里酮，而每毫升根部中仅含有 0.3 微克。

由于叶片中含有大量柃木烷酮（eurycomanone），使用叶片提取的提取物往往会刺激睾酮的合成，因此在短期内比不使用叶片提取的提取物更容易使人激动。这可能会导致某些人失眠。
科学研究表明，较高剂量的玉竹酮可通过抑制芳香化酶来增加游离睾酮。芳香化酶是一种能分解循环中的睾酮并将其转化为雌激素的酶。这就更加尴尬了，因为芳香化酶不仅会减少生物可利用的睾酮，实际上还会将睾酮转化为抗睾酮。优甲乐能限制了这种反应。
如果剂量足够大，优可马龙还能起到磷酸二酯酶抑制剂的作用。要知道，西地那非等药物也是磷酸二酯酶抑制剂。
