目的:研究厚朴有效成分含量与胸径、树高、树皮厚、海拔、经度之间的关系,为厚朴良种选育提供理论基础。方法:以四川西南地区规模化栽培区产厚朴的树皮为研究对象,采用HPLC法检测厚朴酚与和厚朴酚含量,比较不同地区间的质量差异,同时统计分析影响厚朴有效成分含量的关键因素。结果:5个栽培区产厚朴的厚朴酚含量在1.72%~2.70%之间,和厚朴酚含量在1.42%~3.23%之间,总酚含量最高的地区为都江堰(5.16%),最低的地区为汶川(3.69%);厚朴有效成分含量与其胸径、树高、树皮厚、海拔、经度均具有一定相关性。结论:四川西南地区规模化栽培区产厚朴品质较好,其有效成分含量较高;厚朴总酚含量与胸径、树高、树皮厚呈正相关;厚朴酚与海拔呈正相关,和厚朴酚与海拔、经度呈负相关。
Objective: To study the relationship between the content of active ingredients of Magnolia officinalis and DBH, tree height, bark thickness, altitude and longitude, so as to provide the theoretical basis for the selection of Magnolia Bark varieties. Methods: The bark of Magnolia bark was planted in large-scale cultivation area in southwest Sichuan. The content of magnolol and honokiol were measured by HPLC, and the differences of quality among different regions were compared. Meanwhile, Content of the key factors. Results: Magnolol content of Magnolia officinalis in five cultivated areas ranged from 1.72% to 2.70%, and honokiol content ranged from 1.42% to 3.23%. The highest total phenolic content was Dujiangyan (5.16%), The lowest area was Wenchuan (3.69%). The content of active ingredients of Magnolia officinalis had some correlation with its DBH, tree height, bark thickness, altitude and longitude. CONCLUSION: Magnaporthe giganteum in large-scale cultivation area in southwestern Sichuan has better quality and higher effective content. The content of total phenolics in Magnolia officinalis is positively correlated with DBH, tree height and bark thickness. Magnolol is positively correlated with altitude, Paeonol and altitude, longitude was negatively correlated.
