Relationships between appearance and internal quality in Magnolia officinalis

Abstract: 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 .
