“…In the past decade, a considerable body of literature has grown up around the key technologies of the whole industry chain for high-efficiency planting and the intensive processing of C. camphora and C. bodinieri , including phylogenetic analysis based on the genome of camphor tree [ 7 , 8 , 9 ], transcriptome analysis and the identification of genes [ 10 , 11 , 12 ], metabolic pathways and regulatory mechanisms of essential oil biosynthesis [ 13 , 14 ], the effect of exogenous substances during tissue culture [ 15 ], comparative extraction method analysis [ 16 ], antibacterial, nematicidal and antioxidant activity of essential oil [ 17 , 18 ]; thus, the superior individuals of citral chemotype Sect. Camphora species were screened in Nanchang Institute of Technology over the last five years [ 19 ] and the optimal rooting medium for the C. bodinieri citral type was identified [ 20 ].…”

Citral chemotypes Cinnamomum camphora (C. camphora) and Cinnamomum bodinieri (C. bodinieri) are promising industrial plants that contain abundant citral. For a more in-depth study, their significant biological effect, the chemical composition and antioxidant capacity of essential oils of citral-rich chemotype C. camphora and C. bodinieri (EOCC) were determined in the present study. The EOCC yield, obtained by hydro-distillation and analyzed by gas chromatography–mass spectrometry (GC-MS), ranged from 1.45–2.64%. Forty components more than 0.1% were identified and represented, mainly by a high content of neral (28.6–39.2%), geranial (31.8–54.1%), Z-isocitral (1.8–3.2%), E-isocitral (3.2–4.7%), geraniol (1.3–2.6%) and caryophyllene (0.6–2.4%). The antioxidant properties of EOCC were estimated by DPPH, ABTS and FRAP methods. As our results indicated, the antioxidant activity was significantly correlated to oxygenated monoterpenes. The variety of C. bodinieri (N7) presented the best antioxidant profile, given its highest inhibition of DPPH radical (IC50 = 6.887 ± 0.151 mg/mL) and ABTS radical scavenging activity (IC50 = 19.08 ± 0.02 mg/mL). To the best of our knowledge, more than 88% citral of C. bodinieri was investigated and the antioxidant properties described for the first time. Considering high essential oil yield, rich citral content and high antioxidant activity, the N7 variety will be a good candidate for pharmaceutical and cosmetic development of an improved variety.
