terpene

(21) Essential oils contain terpenic hydrocarbons and their oxygenated derivatives, as well as a small amount of volatile aliphatic hydrocarbons and mixtures of aromatic substances derived from phenylpropene.

Antioxidant compounds presented in some essential oils, such as terpenic and phenolic, prevent or delay oxidation processes or even interrupt or delay reactions between peroxyl and hydroxyl radicals (MASTELIC et al., 2008; MIGUEL, 2010; AMORATI et al., 2013).

Squalene is a terpenic hydrocarbon, a precursor of sterols, which has been highlighted due to its health benefits [20].

grandis uses conspecific herbivore-induced volatiles enriched with the aggregation pheromone to locate host cotton plants and that terpenic compounds may be involved in their attractiveness (Magalhaes et al., 2012).

The authors suggest some important structural features for the activity, such as the presence of the phenolic hydroxyl, and a good balance between the polar and nonpolar portion of the structure (alkyl residue and terpenic group).

Shellac contains polyester unit consisting of aleuritic acid and terpenic acid parts (14).The elemental analysis of C, H and N content of shellac sample shows % of C and H as 28.3, 16.5, respectively.

altilis (DC): a source of valuable bioactive terpenic compounds.

Biotransformation of terpenic compounds by fungi I.

A new sulfur-containing spiroketal glycoside, breynin I, and a new terpenic glycoside, breyniaionoside E, together with 10 known compounds, were isolated from the aerial parts of B.
