摘要
采用高效液相色谱法测定了采自国内厚朴主产区的70 个单株的树皮样品的厚朴酚及和厚朴酚含量。结果表明: 厚朴树皮外观性状与内在品质存在显著的相关性。皮厚、表面粗糙、油性足、粉末颜色深和纤维含量少的厚朴品质好, 反之品质较差, 其中, 粉末颜色和皮厚是外观性状中的主要性状。它们是制定厚朴品质标准的最主要外观因素。同时, 也为厚朴遗传改良的品质判别提供简单且可操作的外观指标。表4
Contents of magnolol and honokiol in 70 samples collected from the main growing areas of Magnolia officinalis within the country were analyzed by means of HPLC.The results show that there is a significant correlation between the appearance characteristics of bark and its internal quality.The bark which is thick, rough in appearance, oily, dark in powder color and small in fiber content is of high quality and vice versa.Powder color and bark thickness are main parameters in appearance, which are most important in establishing a quality standard for M.officinalis and simple and operationable in making a judgement of quality in the course of genetic breeding.
