To study the change of paeonol and paeoniflorin, the two major active ingredients contained in Cortex Moutan cultivated in Dianjiang county of Chongqing, due to the change of some influence factors, and explore suitable plant conditions and quality cotrol methods of Cortex Moutan.
Paeonol and paeoniflorin were determined by HPLC in samples from Dianjiang.
The ratio of paeonol and paeoniflorin in Cortex Moutan was regularly influenced by altitude, the growth years and harvest time. Cortex could be cultivated at altitude of 400 m to 800 m but 600 m is the best aria because of the peak of the percentage composition of paeonol and paeoniflorin at 600 m. The first and middle third of October in the fifth year is the best picking time of Cortex Moutan because of the maximum of the percentage composition of paeonol and paeoniflorin.
研究重庆垫江县栽培的牡丹皮中主要活性成分丹皮酚和芍药苷因某些影响因素变化而发生的改变，探索牡丹皮适宜的种植条件和质量控制方法。
采用高效液相色谱法测定垫江样品中丹皮酚和芍药苷的含量。
牡丹皮中丹皮酚与芍药苷的比例受海拔、生长年限和采收时间的规律性影响。牡丹皮可在海拔400米至800米的区域种植，但600米为最佳种植区域，因为在600米处丹皮酚和芍药苷的百分含量最高。第五年10月上旬和中旬是牡丹皮的最佳采收时间，因为此时丹皮酚和芍药苷的百分含量最高。
