摘要 [目的]考察安徽亳州白芍不同采收期有效成分含量的动态变化,结合药材质量、产量和商品性状等因素综合考虑,确定其最佳采收期。[方法]采集亳州地区不同采收期的白芍药材,测定其浸出物、没食子酸、儿茶素、芍药内酯苷、芍药苷和苯甲酰芍药苷的含量,综合评价白芍药材质量。[结果]白芍的有效成分含量随着生长时间显著变化,以5年生所含的有效成分含量最高,而同一年份中以9—10月所含的有效成分含量较高。[结论]综合种植成本、经济效益、药材质量和产量考虑,亳州地区白芍应以4年生9—10月份采收为宜。

Abstract [Objective]To study the dynamic changes of active components in different harvesting time of Paeoniae radix alba in Bozhou City of Anhui Province. The best harvesting time was determined based on the factors of quality, yield and commodity character. [Method]The contents of extracts, gallic acid, catechin, albiflorin, paeoniflorin and benzoyl paeoniflorin were determined by collecting the medicinal materials of Paeoniae radix alba from different harvesting time in Bozhou area and the quality was evaluated comprehensively. [Result]The active components contents of Paeoniae radix alba changed significantly with growth time. The content in five years old was the highest, while the content in the same year was higher from September to October. [Conclusion]Considering planting costs, economic benefits, medicinal material quality and yield comprehensively,Paeoniae radix alba in Bozhou area should be harvested for four years old from September to October.

白芍始載于《神农本草经》[1],为毛茛科植物芍药(Paeonia lactiflora Pall.)的干燥根,味苦、酸,微寒,归肝、脾经,具有养血调经、敛阴止汗、柔肝止痛、平抑肝阳的功效[2]。白芍主产于浙江安阳、磐安(杭白芍)、安徽亳州(亳白芍)及四川中江、渠县、广安(川白芍),其中以安徽亳州产量大、质量好,是白芍道地药材主产区[3]。现代药理研究表明,白芍具有止痛、抗炎、保肝等药理作用,中医临床上用于类风湿性关节炎、系统性红斑狼疮等自身免疫病,疗效确切[4]。
白芍总苷(total glucosides of paeony,TGP)为白芍中提取的主要有效成分,主要含有芍药苷、芍药内酯苷、羟基芍药苷、苯甲酰芍药苷等萜苷类化合物,其中以芍药苷最为典型,含量占芍药总苷中总苷量的90%以上,此外还含有没食子酸、苯甲酸、儿茶素等[5]。……
