Cedrus deodara is a cedar plant from the Pinaceae family. Because Cedrus is widely used in health care products, cosmetics, medicine, and insecticides, the essential oils of Cedrus deodara (CDEOs) are gaining increasing levels of attention. However, there have only been a few studies on the anti-inflammatory effects of CDEOs. This study aimed to systematically study the composition and biological effects of CDEOs, in line with this, the study assessed the chemical composition of CDEOs and evaluated their anti-inflammatory mechanisms in mice. Gas chromatography-mass spectrometry (GC-MS) was used to determine and analyze a total of 41 compounds from CDEOs. It was found that the major components of CDEOs are thujopsene (28.23%), α-cedrene (17.01%), and cedrol (15.55%); moreover, our results showed that the active ingredients in CDEOs have anti-inflammatory and antioxidant effects and that the active ingredients in CDEOs can be used as an antioxidant, as an important biological resource in functional food, and as ingredients in cosmetics and pharmaceuticals. Taken together, these CDEOs serve as ideal additives for anti-inflammatory drugs.
