1、福建警察学院学生毕业论文（设计）关于抗癌中草药有效成分的研究学生姓名：钟标平学号：1130217962系部：法律系专业：法学指导教师：10摘要：癌症已成为仅次于心血管疾病的人类第二类杀手，目前抗癌常用化疗与放疗的方法可造成对人体不利的严重毒副反应。从化学合成药物寻找抗癌药的难度远远超过从传统中药寻找新药。因此，使用中草药来抗癌，寻找抗癌中草药的有效成分，并对其进行化学、药理及临床研究，成为国内外药物化学工作者的研究重点之一。本文将通过探讨了中草药及其有效成分在抗癌中的研究现状,为进一步从中草药中发掘高效低毒的抗癌创新药物提供参考。关键词：抗癌；中草药；有效成分；研

6、子药理学对癌症本质和作用机制方面的阐明,抗癌中草药有效成分的研究水平有了明显提高。本文将通过对抗癌中草药的有效化学成分的研究进行综述对近些年来的抗癌中草药化学研究前沿文献进行整理、分析与总结。从而加强对中草药抗癌有效成分研究。坚持以中医药理论为基础，与国际接轨。学习使用先进科学手段与标准，确立以疗效为中心的指导思想。化学为药效服务，利用生物工程技术，从传统中草药中筛选抗癌有效成分。近几十年来,我国广大医药工作者在中草药及其有效成分的抗癌作用研究方面进行了大量的实验与研究,取得了丰硕的成果。现将近年来关于抗癌中草药有效成分的研究概况综述如下：1.抗癌中草药10很多中

7、药研究者，对现有的中药资源进行了体内外抗癌症筛选试验研究，实验结果显示，很多中药具有不同程度的抗癌作用。临床常用抗癌中药有白花蛇舌草、夏枯草、七叶一枝花、凤尾草、半枝莲、天冬、补骨脂、薏苡仁、黄芪、人参、党参、虫草、女贞子、丹参、当归、莪术、姜黄、柴胡、姜黄、陈皮、雷公藤等等。1.1莪术中药莪术中主要抗癌成分为p一榄香烯(B—Elemene)。托娅报道，p一榄香烯能明显抑制3H—TdR和3H—UdR掺人癌细胞，从而抑制DNA和RNA的合成，使细胞中的核酸含量降低，尤其RNA的下降更明显，从而使癌症细胞发生凋亡。还有实验证明，莪术对DNA聚合酶也有明显抑制作用。1.
