| Chemically, the camphors may be divided into two main groups, according to the nature of the corresponding hydrocarbon or terpene. |
| As shown, the extract tested by the NTP contains about one third more flavone glycosides and nearly twice the amount of terpene lactones and ginkgolic acids. |
| This is the rich material from which Carbocycle Construction in Terpene Synthesis is derived. |
| The principal constituents of the oil are a terpene, asarol alcohol, another alcohol, and methyl eugenol. |
| The terpene from American turpentine is called austraterebenthene. |
| Plants and some other organisms have an additional terpene biosynthesis pathway in their chloroplasts, a structure fungi and animals do not have. |
