Steam distillation of C.decurrens heartwood gave 0.6% of an essential oil composed mainly of p-cymene and p-menthane derivatives. Thymoquinone (35.9%), carvacrol (29.2%), p-methoxythymol 11% and p-methoxycarvacrol 3.2% were the main components. "The tropolone [[http://www.thegoodscentscompany.com/data/rw1044801.html|beta-thujaplicin]] (hinokitiol) was only present in trace amounts. The high concentrations of thymoquinone and carvacrol alone can account for the previously observed high bioactivity of this oil. Carvacrol is well known for its antimicrobial, antioxidant, insecticidal, and repellent activities." \\ | Steam distillation of C.decurrens heartwood gave 0.6% of an essential oil composed mainly of derivatives of p-cymene and p-menthane.
