如何正确看待传统中医药在发现青蒿素中的作用 摘要：中国青蒿素及其衍生物的成功研制与发展已经被广泛用于全球抗疟，是中医药对全世界人民的又一 杰出贡献。屠呦呦因此在2011年9月获得美国拉斯克医学奖之后，又获得了2015年诺贝尔生理学与医学奖。但是伴随着这些荣耀而来的诸多质疑同样值得我们思考。 关键词：屠呦呦，中医药，青蒿素，诺贝尔奖，争论 How to Regard the Role of Traditional Chinese Medicine in the Artemisinin Discovery Process Abstract：The successful research and development of artemisinin and its derivatives in China and is widely used in the global malaria, is one of the important contribution to the Chinese medicine pharmacy benefit all mankind.After won the Lasker Medical Research Awards in September 2011, Tu Yoyo won the 2015 Nobel Prize in physiology or medicine.Concomitant with the honor of dispute is also worth thinking about Keywords: Tu Yoyo; Traditional Chinese Medicine; Artemisinin; Nobel Prize; Dispute 引言：青蒿素的发现在全世界范围内拯救了数百万人的性命，屠呦呦也因此成为第一位获得诺贝尔科学奖的本土科学家，也是第一位获得诺贝尔生理学或医学奖的中国科学家。在我们为此成就无比自豪的同时，关于传统中医药在青蒿素发现过程中到底扮演了怎样的角色在全球学术范围里引起了巨大的争论。本文将讨论如何正确看待传统中医药在青蒿素的发现中的作用，以及该如何看待中医药在现代医学中的地位。 1 两个不同的观点 1.1 20世纪70年代，接到国家的任务，屠呦呦加入了523工程，致力于治疗疟疾的研究。收集了大量关于治疗疟疾的古代药方，并把这些药方归纳整理，命名为《抗疟单验方集》【1】。这本验方集收录了超过600多种中草药，其中就包括了青蒿。关于青蒿入药，最早见于马王堆三号汉墓的帛书《五十二病方》，其后的《神农本草经》、《肘后备急方》等中药典籍，都有青蒿治疗疟疾的经验记载和自洽的理论解释【2】。 屠呦呦从东晋葛洪的《肘后备急方》中“青蒿一握，以水二升渍，绞取汁，尽服之。”得到 灵感【2】，创造性的在低温环境中成功的提取出了青蒿素，并得到很高的临床抑制率。在接下来的猴 子实验以及人体实验都取得了显著的治疗效果。 基于上面的研究历史，一些人则认为，青蒿素的发现完全是基于中医药的贡献，因为无论是从发 现青蒿这一层面还是低温提取这一关键性问题的解决，都是从葛洪《肘后备急方》中得到的灵感。可 以这么说，如果没有传统中医药的帮助，青蒿素的发现也会被推迟很长的一段时间。 1.2 与之相反的是另一种针锋相对的观点，这也是我们讨论的重点。 首先，关于青蒿素的提取工艺-低温乙醚提取【3】，是完全运用现代科技的方法，与传统中医药的煎煮方式完全不同。而恰恰是这种提取工艺避免了高温对青蒿素的破坏，保存了青蒿中的有效成分，如果坚持运用传统工艺煎煮，将很难得到有效成分。 其次，他们认为，记载在古代医术的治疗疟疾的药方很多，但是绝大多数的药方运用在科学实验中很难得到令人满意的结果。即使是葛洪的方法也没有得到古人的绝对认可与重视，因为古人并没有像现代医学一样，有一个类似指南的文件，把青蒿治疗疟疾上升到另一个高度，而还是停留在个人的经验上。 还有一点就是，中医药里所说的青蒿和青蒿素是完全不同的两种东西。用化学术语来解
