2. Magnolia Officinalis Bark Extract Source
Magnolia officinalis (Latin scientific name: Magnolia officinalis Rehd. et Wils.) is a deciduous tree plant. The content of magnolol in different parts of Magnolia Bark is quite different. The total content of magnolol in magnolia bark and branch bark is 2.30%, and the total content of magnolol in magnolia root bark is 8.22%. However, Magnolia officinalis grows slowly and has a long growth cycle. Magnolia officinalis is now listed as a national second-level wild protected plant in China. Therefore, extracting magnolol from the plant causes serious damage to resources. Nowadays, there are also chemical methods for preparing magnolol. The synthesis method is highly efficient and can also protect plant resources.
