13. Due to the ease and high yield of this chemical transformation, it had been expected since 1978 that isobarbartene should also be a natural constituent of sesquiterpene-rich essential oils. Recently, it was isolated for the first time from the roots of the higher plant Meum athamanticum (L.) Jacq. See: Koenig, W.; Rieck, A.; Saritas, Y.; Hardt, I. H.; Kubeczka, K.-H.
