The magnolol powder is a natural bisphenolic compound extracted from the bark of the Magnolia officinalis tree. It appears as fine brownish-yellow crystals or powder, with the unique aromatic aldehyde aroma and a mild pungent sensation of the magnolia plant. Its molecular structure is centered on a biphenyl framework, combining the strong antioxidant and lipophilic properties of phenolic hydroxyl groups, enabling it to effectively penetrate biological membranes and exert its effects. This component is the core active substance of the magnolia medicinal material, demonstrating broad-spectrum pharmacological activities: it not only has significant inhibitory effects on Gram-positive/ negative bacteria and fungi, but also can produce sedative and anti-anxiety effects by regulating GABA receptors, and has multiple biological activities such as anti-inflammatory, antioxidant, anti-tumor, and protection of the gastrointestinal mucosa. In clinical applications, magnolol powder is an important raw material for digestive system drugs (such as relieving abdominal distension and promoting gastrointestinal motility) and oral care products. At the same time, it is widely used as a natural preservative in the food and cosmetic industries. Its unique natural origin and multi-target action mechanism make it occupy an important position in modern Chinese medicine preparations and green health products.
