天然药物化学主要是研究药用植物或植物中具有生理活性成分的科学。它是随着分离技术和鉴定方法愈趋于微量、快速而发展的。二十世纪初有机元素的微量分析法问世以后,对植物化学成分研究的发展,起到重大的推进作用。特别是近二、三十年中发展的各种层析分离技术和各种光谱分析法,对天然药物成分复杂、含量太少,不易分离和无法进行结构测定的困难,得到很大程度的
Natural medicine chemistry is mainly a science that studies medicinal plants or plants that have physiologically active ingredients. It is with the separation technology and the identification method becoming more and more micro, rapid and development. After the introduction of the microanalysis of organic elements in the early 20th century, the development of phytochemicals has played a major role in advancing the research. In particular, various chromatographic separation techniques and various spectroscopic analysis methods developed in the last two to three decades have caused a great degree of difficulty in the complexity, low content, difficulty in separation, and inability to structure determination of natural medicines.
