大孔吸附树脂纯化栀子中总环烯醚萜苷和栀子苷的研究

目的建立栀子中总环烯醚萜苷测定方法,研究HPD 450大孔吸附树脂纯化栀子总环烯醚萜苷、栀子苷的工艺条件。方法采用紫外分光光度法和高效液相色谱法测定目标成分,考察HPD 450大孔吸附树脂对栀子总环烯醚萜苷、栀子苷的吸附和洗脱条件。结果栀子总环烯醚萜苷最大吸收波长为238 nm,与栀子苷一致,栀子苷在9.36~21.84μg/mL与吸光度呈良好线性关系,平均回收率为98.37%;HPD 450大孔吸附树脂可以将提取物中总环烯醚萜苷由45.45%提高到83.72%,栀子苷由24.46%提高到62.28%。结论HPD 450大孔吸附树脂能有效富集并纯化栀子总环烯醚萜苷、栀子苷;紫外分光光度法测定栀子总环烯醚萜苷具有快速、准确的特点。

Objective To study the solubility of lipo-alkaloids from prepared aconite root(Radix Aconiti Lateralis Preparata) and identify the sources of lipo-alkaloids in Sini Decoction.Methods The electrospray ionization mass spectrometry was employed to analyze the alkaloids in crude aconite roots,Sini Decoction,the gruffs of concocted aconite roots and the decoction of prepared aconite root and pinellia tuber(Rhizoma Pinellae).Results Lipo-alkaloids were observed in Sini Decoction,however,no lipo-(alkaloids) were found in the decoction of aconite roots with pinellia tuber.Lipo-alkaloids were the dominant components in the gruffs of concocted aconite roots.Conclusion Lipo-alkaloids are barely soluble in boiling water.The alkaloids existed in the Sini Decoction stem from the ester-exchange reactions of diester-diterpenoid alkaloids and fatty acid in the boiling water
