| 摘 要： | 浙、闽、川、湘、桂、赣、鄂 7省11县76个不同树龄厚朴样本,采用高效液相色谱(HPLC)测定厚朴酚类含量,以研究树龄对厚朴有效成分的影响。结果表明:年龄对厚朴酚类含量的影响与栽培的品种有关,年龄对凹叶型厚朴的酚类含量影响不大;其它类型的厚朴酚类含量随年龄增大、树干长粗、树皮加厚而迅速增加,12年以后基本稳定。树龄增大可能有利于油性性状的充分发挥。本结果为厚朴人工林最佳采收年限的确定提供了科学依据。

| Abstract: | Contents of magnolol and honokiol in 76 samples of Magnolia officinalis collected from 11 counties in Zhejiang, Fujian, Sichuan, Guangxi, Hunan, Jiangxi and Hubei are analyzed by means of HPLC. A study on the effect of tree age on effective ingredients in Magnolia offcinalis shows that the influence of tree age on the content of magnolol and honokiol is correlated with the varieties under cultivation, but a small effect on the content of the phenols with an indent at the tip of leaves.The content of magnolol in other types of leaves increases rapidly with increase in age, diameter of the trunk and thickness of the bark, with not many changes found at the age of 12 or up.Increase in age may be favorable to the full expression of oily characteristic.These results provide a scientific base for the determination of optimal time for harvesting bark from artificially established Magnolia offic-inalis stands. |
