Camellia reticulata is a typical Camellia species used for the production of edible oil in Southwest China. Here we analyzed the fatty acid composition and bio-active compounds including tocopherol, sitosterol and squalene in C. reticulata oil. The oil mainly comprises 72.78–75.52% oleic acid, 11.40–12.58% palmitic acid, 6.91–8.01% linoleic acid, 2.29–2.98% stearic acid, 0.33–0.52% linolenic acid. The average content of α-tocopherol, β-sitosterol and squalene in solvent extracted C. reticulata oils from six sites are 27.19 mg per 100 g, 289.47 mg kg⁻¹ and 138.28 mg kg⁻¹, respectively. We also evaluated the effect of elevation, an important environment factor influencing seed oil content, on fatty acid composition and bio-active compounds of C. reticulata oil. The results indicated that only β-sitosterol content showed significant difference at the different elevations.
