芍药根化学成分分布及加工工艺研究

Study on chemical components distribution in Paeoniae Radix Alba and its processing methods

对芍药根内化学成分的分布规律进行研究,发现在同一根段的不同部位及同一植株的不同根段中,芍药内酯苷、芍药苷、苯甲酰芍药苷、丹皮酚的含量均具有一定差异。为减小样品质量差异对实验结果产生的影响,选择处理前后的化学成分含量变化百分率为评价指标,对白芍加工工艺进行研究,初步得白芍的加工方法：将芍药根置于沸水中煮制,时间不得超过10 min,再去除外皮,切2~3 mm薄片,于55℃下烘干,与亳白芍传统加工工艺较一致。白芍加工中的去皮、煮制、干燥工艺对芍药内酯苷、芍药苷、苯甲酰芍药苷和丹皮酚的含量有不同程度的影响。

After studying the discipline of chemical components distribution in peony root, it was found that the content distribution of albiflorin, paeoniflorin, benzoylpaeoniflorin and paeonol was inhomogeneous in different parts of peony root, as same as in different roots belonging to a same plant. Therefore, in order to minimize the effects of different qualities of materials on experimental result, the content changing percentages of four chemical components was chosen as indicators to study processing method of Paeoniae Radix Mba. The processing technique of Paeoniae Radix Alba was put peony roots in the boiled water for at most ten minutes, and cut them into 2-3 mm slices after peeling the root bark, finally dry them in a oven under 55 ℃, which was similar to the traditional processing method used in Bozhou. And the peeling, boiling and drying methods would affect the contents of albiflorin, paeoniflorin, benzoylpaeoniflorin and paeonol on several levels.
