Hyptis suaveolens (L.) Poit (Bush Tea): Volatile composition of fruits and stems essential oils

Abstract

Hyptis suaveolens is an aromatic and medicinal plant harvested in the wild. The volatile oils isolated from the fresh fruits and stems of H. suaveolens were subjected to gas chromatography-mass spectrometry (GC-MS). GC-MS analyses permitted the identification ofthirty-six constituents, accounting for 98.0% and 99.4%composition of the fruits and stems oils respectively. The oxygenated terpenes (66.8%) and terpenoid hydrocarbons (75.5%) predominated the fruits and stems oils respectively. The fruits volatile oil was characterized by the abundance of 1, 8-cineole (29.5%), fenchone (17.2%), fenchol (9.5%), and sabinene (8.4%). The main components of the stems oil were β-pinene (20.9%), estragole (16.3%), β-caryophyllene (11.1%), and α-pinene (6.8%). The composition of the fruits essential oil of H. suaveolens is reported for the first time.
