Objective: To conduct quality analysis on 4 different batches of samples of Angelica sinensis decoction pieces with different appearance characters, and explore the establishment of preparing and processing standards and quality standard. Methods: Detected each sample via microscopic identification, thin layer chromatography, determination of volatile oil and high performance liquid chromatography. Results: Among the 4 batches of samples of Angelica sinensis decoction pieces,the contents of extract,volatile oil and ferulic acid in the samples 3# were all higher than those in the samples1#,2# and 4#. In terms of smoothness, oil enrichment and thick aroma, the quality of the samples 3# was better;in terms of inapparent external oil smoothness, light aroma, cracks in the section and relatively dry texture, the quality of the samples1#,2# and 4# was comparatively worse. Conclusion: There exists difference in the quality of samples of Angelica sinensis decoction pieces with different appearance characters. When the quality standard of Angelica sinensis is established, it is also significant to establish the preparing and processing standards.
