摘要:目的 研究不同配伍比例对当归补血汤化学成分和促血管新生作用的影响。方法 采用高效液相色谱法测定不同配伍比例当归补血汤中的主要化学成分阿魏酸、毛蕊异黄酮苷、毛蕊异黄酮和芒柄花素含量;采用转基因斑马鱼模型比较不同配伍比例当归补血汤的促血管新生作用。结果 随着黄芪含量的增加,不同配伍比例煎液指标成分综合得分有上升趋势,且在黄芪与当归之比为8∶2与5∶1时综合得分最高。对于斑马鱼血管损伤模型,血管恢复率排名前3位的配比分别是黄芪与当归之比为5∶1、6∶1和2∶1。结论 从化学成分及促血管新生疗效综合分析,黄芪与当归经典配伍比例(5∶1)好于其他比例。

Abstract: Objective To study chemical ingredients and angiogenesis effects for different compatibility proportions of Danggui Buxue Decoction. Methods For chemical components, HPLC was performed to study the ingredients (Ferulic Acid, Calycosin-7-glusosido, Calycosin, Formononetin) in Danggui Buxue Decoction. For angiogenesis effects, transgenosis zebrafish model was incubated with different proportions of Danggui 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.

当归补血汤为补血的代表方剂,由黄芪和当归2味药组成,用于治疗血虚发热证,亦治妇人经期、产后血虚发热头痛,或疮疡溃后、久不愈合等[1]。药理研究表明,当归补血汤具有保护心肌缺血再灌注引起的心功能减弱、促进造血、改善血液黏度等作用[2-4],临床资料显示其对冠心病、心绞痛等心血管疾病具有很好的疗效[5-6]。历代医家对当归补血汤证的病机、主治及用药法度皆有争议。或云为气虚而设,君黄芪补气为主;或云为血虚而设,君当归补血为主;也有说为气血兼治,用于气血两虚证的治疗[7]。因此,当归补血汤中2味中药的用药剂量在中医古籍中有许多种用法,而药物剂量的变化直接影响有效成分含量和治疗作用。……
