Abstract

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.

考虑产地、株龄、采收期和基因型的凤丹牡丹资源评价

牡丹皮是中国传统上用于治疗多种疾病的重要药材，已有数千年的历史。牡丹皮的主要原料是凤丹牡丹。该药物的质量和疗效受产地、种植年龄、收获时间和基因型的影响较大。为了生产出优质的牡丹皮，本研究以新产区延庆和两个主要已建立的产区亳州和菏泽为研究对象，对牡丹皮的生长参数、营养成分和丹皮酚含量进行了研究。结果表明，延庆8月牡丹皮酚含量显著高于亳州和菏泽8月和10月的牡丹皮酚含量，表明延庆是牡丹皮生产的理想产区。为了进一步确定最佳采收期，检测了生长参数和代谢物的年度变化。结果表明，7月份丹皮酚含量最高，整个8月份次之。此外，我们发现随着年龄的增长，茎部生长参数和黄酮类化合物的积累量增加。根生长参数、类黄酮和丹皮酚含量在前5年呈上升趋势，后5年保持稳定。这些结果表明，牡丹皮应采自5年生的植株。此外，还对60个基因型的丹皮酚含量进行了评价。大部分（85%）根中丹皮酚含量超过1.2%。三分之二的根含有1.5%的丹皮酚，而三分之一的单株含有2.0%的丹皮酚。鉴定出2个有前途的基因型（含>； 3%丹皮酚）和5个含2.5 ~ 3.0%丹皮酚的基因型（含2.5 ~ 3.0%丹皮酚）。总体而言，本研究为牡丹皮的生产提供了广阔的发展空间，鉴定出7个丹皮酚含量较高的基因型，并确定了最佳采收时间，对牡丹皮的生产和优质品种的选育具有重要意义。

期刊介绍： Scientia Horticulturae is an international journal publishing research related to horticultural crops. Articles in the journal deal with open or protected production of vegetables, fruits, edible fungi and ornamentals under temperate, subtropical and tropical conditions. Papers in related areas (biochemistry, micropropagation, soil science, plant breeding, plant physiology, phytopathology, etc.) are considered, if they contain information of direct significance to horticulture. Papers on the technical aspects of horticulture (engineering, crop processing, storage, transport etc.) are accepted for publication only if they relate directly to the living product. In the case of plantation crops, those yielding a product that may be used fresh (e.g. tropical vegetables, citrus, bananas, and other fruits) will be considered, while those papers describing the processing of the product (e.g. rubber, tobacco, and quinine) will not. The scope of the journal includes all horticultural crops but does not include speciality crops such as, medicinal crops or forestry crops, such as bamboo. Basic molecular studies without any direct application in horticulture will not be considered for this journal.
