To study the chemical constituents of paeoniflorins from root cortex of the Paeonia suffruticosa.
Paeoniflorins were isolated by partition, silica gel column chromatography, medium-pressure RP chromatography and HPLC. Their structures were elucidated by spectroscopic methods including IR, MS and NMR techniques.
Nine paeoniflorins were isolated and identified from the root bark ethanol extract of P. suffruticosa.
The new compound was identified as paeoniflorin-4-ethyl ether, which may be an artifact produced during extraction proved by simulate experiment.
研究牡丹根皮中芍药苷类化学成分。
采用溶剂分配、硅胶柱色谱、中压反相色谱及高效液相色谱等方法分离芍药苷类成分，运用红外光谱、质谱及核磁共振等波谱技术鉴定其结构。
从牡丹根皮乙醇提取物中分离鉴定出9个芍药苷类成分。
新化合物鉴定为芍药苷-4-乙醚，模拟实验表明其可能是提取过程中产生的假象。
