Chemically, the camphors may be divided into two main groups, according to the nature of the corresponding hydrocarbon or terpene.

Hence it is a hydrocarbon of the terpene series, having the general formula CnH2n-4.

It has not yet been converted again into terpene, but the connection is sufficiently proved.

The principal constituents of the oil are a terpene, asarol alcohol, another alcohol, and methyl eugenol.

They are usually present in the plant oil in mixtures with each other or with a terpene.
