  Medicinal Uses: Magnolia flower oil has a strong ability to scavenge free radicals. When the mass concentration reaches 20 μg/mL, the removal rate is comparable to that of ascorbic acid. Magnolia flower essential oil contains abundant terpenoid oxides and terpenoid compounds, such as linalool (11.06%), citronellol (9.94%), eucalyptol (3.95%), caryophyllene (37.94%), and β-pinene (2.67%). These compounds containing methylene and hydroxyl groups are chemically active and easily oxidized, giving the essential oil its antioxidant activity. The easily oxidized nature of the essential oil requires it to be stored in a brown bottle, protected from light, at a low temperature, and sealed. Otherwise, the aroma-enhancing, antioxidant, and antibacterial active ingredients are easily destroyed. Magnolia flower essential oil has an inhibitory effect on bacteria and fungi, especially on red yeast. When the essential oil mass concentration in the culture medium is 5.00 mg/mL, it can completely inhibit the growth of red yeast in the culture medium. Red yeast is widely distributed in nature and is one of the microorganisms that cause food spoilage, especially easily causing spoilage of foods with high sugar content. Magnolia flower essential oil can be used in the food industry not only as a flavoring agent but also as a preservative. Therefore, magnolia flower essential oil has certain development and utilization value.;
