Magnolia Bark Extract

Magnolia Bark Extract

Magnolia officinalis contains about 1% volatile oil, and the oil mainly contains β-eudesmol (Machilol), which accounts for more than 95% of the volatile oil. It also contains about 5% of magnolol and its isomers. In addition, it also contains a small amount of magnocurarine and tannins. In addition to magnolol, magnolol, β-eudesmol and a small amount of magnocurarine reported in the literature, the chemical composition of Magnolia officinalis also includes a new allylbenzene-p-benzoquinone compound magnoquinone obtained from the ethyl acetate part of the dry bark of Magnolia officinalis and seven known new wood ester compounds. Among them, magnolol and honokiol are a pair of isomers, and the high content of the two is the main basis for Magnolia officinalis to be used as a substitute for Magnolia officinalis. The active ingredients of Magnolia officinalis extract are honokiol, magnolol, and total magnolol.
