Ingredient Profile & Common Uses
Magnolol, CAS 528-43-8, occurs naturally in Magnolia officinalis bark and is chemically identified as 5,5′-diallyl-2,2′-dihydroxybiphenyl. Unlike conventional bark powders and ratio extracts, the purified ingredient is commercially defined by the concentration of one target phytochemical. This distinction makes it more appropriate for projects requiring a chemically characterized Magnolia-derived active rather than the broader constituent profile of a botanical extract.
Commercial grade selection centers on individual magnolol purity and the analytical method used to quantify it. The ≥98% HPLC grade is distinct from Honokiol 98% and from specifications based on combined magnolol and honokiol. For purchasing and QA teams, this distinction is important because products described broadly as “Magnolia phenols” may represent different analyte compositions even when their headline percentage appears similar.
The high-assay material is used in concentrated botanical-active development, dietary supplement formulation, cosmetic and personal-care R&D, and specialty premixes. Its low aqueous solubility and lipophilic character make carrier selection, wetting, dispersion, blend uniformity, and precipitation control more relevant to formulation development than the extraction-ratio parameters normally used for conventional botanical extracts.
