Objective: To study the effects of different origins, collection and processing methods on the quality of Taraxacum mongolicum. Methods:The HPLC fingerprints of Taraxacum mongolicum were established. Totally 11 batches of Taraxacum mongoli-cum were analyzed by similarity evaluation and cluster analysis. Results:According to the results of HPLC, 11 batches of Taraxacum mongolicum had good baseline separation and showed 5 common peaks. Based on the established HPLC method, the quality of different batches of Taraxacum mongolicum showed difference according to the results of similarity evaluation and cluster analysis. The quality of batch 121231-1 was the best. Conclusion:The origin, collection and processing method show notable influence on the quality of Ta-raxacum mongolicum, and the comprehensive score method can be applied in the quality evaluation of Chinese herbs.

Objective To study chemical ingredients and angiogenesis effects for different compatibility proportions ofDanggui Buxue Decoction.Methods For chemical components, HPLC was performed to study the ingredients (Ferulic Acid, Calycosin-7-glusosido, Calycosin, Formononetin) inDanggui Buxue Decoction. For angiogenesis effects, transgenosis zebrafish model was incubated with different proportions ofDanggui Buxue Decoction.Results With the raise of Astragali Radix content, the synthetic scores of four ingredients in different compatibility proportions increased. When the Astragali Radix content to Angelicae Sinensis Radix content was 8 to 2 and 5 to 1, the scores were the highest. For zebrafish vascular injury model, vessel recoveries in top three were 5:1, 6:1 and 2:1 (Astragali Radix: Angelicae Sinensis Radix).Conclusion From comprehensive analysis of chemical composition and angiogenesis, the best compatibility ratio of Astragali Radix to Angelicae Sinensis Radix is 5:1.
