摘要： Cortex Moutan is an important crude drug traditionally used in China to treat diverse diseases for thousands of years. The main source of Cortex Moutan is Peaonia ostii 'Fengdan'.The quality and efficacy of this medication were highly affected by the production area, plant age, harvest time, and genotype. To produce high quality Cortex Moutan, the growth parameters and the contents of nutrients and paeonol were studied in the Yanqing District, a new production area, and the two main established production areas, Bozhou and Heze, in this study. The results showed that the paeonol was significantly higher in Yanqing in August than that of Bozhou and Heze in both August and October, showing that Yanqing is a promising area for the production of Cortex Moutan. To futher determine the best harvest time, the annual changes in growth parameters and metabolites were detected. The results showed that paeonol content was the greatest in July, followed by the whole August. Moreover, we found that the shoot growth parameters and the accumulation of flavonoid increased with ages. The root growth parameters and the content of flavonoid and paeonol increased during the first 5 years and then remained stable afterwards. These findings indicated that the Cortex Moutan should be harvested from the 5-year-old plants. In addition, the content of paeonol in 60 genotypes was evaluated. The paeonol content in most (85 %) roots exceeded 1.2 %. Two-thirds of roots contained >1.5 % of paeonol, while one-third of the individual plants contained >2.0 % of paeonol. Two promising genotypes with a content of >3 % of paeonol and five genotypes with 2.5-3.0 % of paeonol were identified. Overall, this study provids a promising area for Cortex Moutan production, identified seven genotypes with a high content of paeonol, and specified the best time for harvest, which is highly significant to produce Cortex Moutan and breed high-quality cultivars.
