monoterpenoidn.adj.

Brit.

/ˌmɒnə(ʊ)ˈtəːpᵻnɔɪd/, U.S.

/ˈˌmɑnəˈtərpəˌnɔɪd/

Origin: Formed within English, by compounding. Etymons: mono- comb. form, terpenoid n.

Etymology: < mono- comb. form + terpenoid n., after monoterpene n. Compare earlier diterpenoid n. at diterpene n. Derivatives, polyterpenoid adj. and n. at poly- comb. form 2, triterpenoid n. at tri- comb. form 3a.

Chemistry.

A. n.

A compound that is either a monoterpene or a simple derivative of one.

2000 Biochem. Systematics & Ecol. 28 177 The total base fraction of A. bifolia yielded a nonbasic monoterpenoid known as Muller's lactone, presumed to be an artifact of the isolation procedure.

B. adj.

Of the nature of a monoterpenoid.
