ABSTRACT
The study on natural product chemistry plays an important role in drug development, and the structure elucidation is one of the vital tasks in the natural product chemistry research. This paper summarized the application of UV, IR, MS, and NMR spectra in the structure elucidation of natural products with 123 papers cited. This article is one of the series of historical stories on natural product chemistry published in this journal, which are reviewed and summerized. The developing future is looked forward.
ABSTRACT

This article is one of the series of historical stories on natural product chemistry written by the authors.
ABSTRACT
Objectives to evaluate the quality of examination paper of natural product chemistry of clinical pharmacy for Grade 2005 so as to feed back teaching information and provide gist for improving the teaching quality.Methods Selecting examination paper of all the students of clinical pharmacy to analyze.Results The examination achievement accords with normal distribution with average(78.64?11.12),difficulty 0.62 and discrimination 0.40.Conclusion The model of the paper has the full-scale distribution,the discrimination is good,and it evaluates the mastery level of the students quite objectively.The training of students analysis ability and comprehensive judging ability should be strengthened in the future.
