The phytochemical screening was carried out to detect the presence of secondary metabolites such as alkaloids, flavonoids, quinones, polyphenols, tannins, saponins, steroids, monoterpenoid, triterpenoid, and sesquiterpenoid
were performed following the method described by Farnsworth.
The essential oils of plants from Costa Rica resemble the composition of the oil from Venezuelan origin, but differ from both Brazilian and Venezuelan essential oils by the presence of sesquiterpenoids
of the guaiane carbon skeleton, some of them as prominent members: viridiflorol, globulol, and spathulenol.
Beyond monoterpenoids, the seasonality can also influence the contents of sesquiterpenoids

Other potential sources of alkylnaphthalene include the thermal degradation of spores, coals, and sporopollenin (Allan and Larter, 1981), and of kerogens and cyclic sesquiterpenoids
present in resinous components (Anderson et al, 1992).

Malvaceae: The first sesquiterpenoids
discovered to be nematotoxic were the aldehydes hemigossypol and 6-methoxyhemigossypol, in addition the dimmers gossypol, and 6-methoxygossypol.
Some other constituents including monoterpenoids, sesquiterpenoids
, triterpenoids and steroids were also identified (MARTINS et al.
pinene, phellandrene, eucalyptol) and sesquiterpenoids
(aromadendrene, globulol), respectively, present in Eucalyptus sp.
