咖啡碱咖啡碱caffeine一种生物碱。分子式C8H10N4O2。存在于茶叶、咖啡和可可中。重升华制得的咖啡碱为六角形棱柱状晶体。熔点238℃，178℃升华，密度1.23克／厘米3（19℃）。溶于水、乙醇、丙酮和氯仿，易溶于吡啶、四氢呋喃和乙酸乙酯，微溶于乙醚和苯。咖啡碱的盐酸盐、硫酸盐、磷酸盐均易溶于水或乙醇，并分解成游离碱和酸。其盐酸盐在80～100℃分解，析出水和HCl。目前咖啡碱主要靠人工合成，或为工厂生产不含（或低含量）咖啡碱的咖啡时的副产品。咖啡碱具有兴奋中枢神经作用，医药上可用作心脏和呼吸兴奋剂，是利尿合剂的成分之一。咖啡碱是重要的解热镇痛剂，是复方阿司匹林和氨非加的主要成分之一。在美国等国家咖啡碱大量用作可乐等饮料的添加剂。咖啡碱的半数致死量为200毫克／千克（大白鼠口服）。
