adiantifolia: The methanol extract (CAM), n-hexane (CAH), dichloromethane (CAD), ethyl acetate (CAE) and water (CAW) fractions were studied qualititavely for the presence of alkaloids, flavonoids, saponins, terpenoids, diterpenes
, triterpenoids, anthraquinones, anthranol glycosides, reducing sugars and phenols using different test protocols.
, triterpenes and steroids from flowers of Wedelia paludosa.
Sesquiterpenoids and diterpenes
(including the retinoids), and tetraterpenes (carotenoids such as a and a carotene, lutein, lycopene, zeaxanthin and cryptoxanthin) are of the ingredients of H.
New Delhi-beta-lactamase, Diterpenes
, Infectious diseases, Antibiotic resistance.
These effects can be attributed to the presence of substantial and possible synergies of the chemical components viz., anthraquinones, coumarins, anthracene derivatives, mono-, sesqui- and diterpenes
, triterpenes and steroids, as well as water-soluble tannins.
Potentiation of methicillin activity against methicillin-resistant Staphylococcus aureus by diterpenes
. FEMS Microbiol Lett 1999; 179: 233-239, doi: 10.1111/j.1574-6968.1999.tb08733.x.
pallida rhizomes were fatty acids (89%), alkanes (8.29%), aromatic compounds (1.36%), sesquiterpenes (4.53%), and triterpenes (0.69%); monoterpenes and diterpenes
were not found.
Phytochemlcal studies have indicated the occurrence of diterpenes
and sesquiterpenes in ethanolic extract obtained from the leaves of G.
Significant chemical constituents of horehound are diterpenes
marrubiin and marrubenol, with confirmed vasodilatory effects.
When grouping the components into different terpenoid types, there were found eight monoterpenes hydrocarbons (MH), 17 oxygenated monoterpenes (MO), 11 sesquiterpene hydrocarbons (SH), five oxygenated sesquiterpenes (SO), and one oxygenated diterpenes
The species belonging to the Asteraceae family are characterized by their abundant biological activity , which results from their chemical composition, including secondary metabolites such as terpenes, diterpenes
, flavonoids, and coumarins .
(2012) reported the presence of fatty acids and their esters, aromatic acids, sesquiterpenes, diterpenes
, triterpenes, and flavonoids among others, on propolis collected from Antioquia.
Tricyclic sesquiterpenes and futher diterpenes
from Espeletiopsis species.
In turn, diterpenes
promote the scavenging of free radicals, which results in the inhibition of lipid peroxidation [46, 47].
Secondary metabolites tested included alkaloids, terpenoids, diterpenes
, flavonoids, phenolics, saponins, anthraquinones, steroids, and tannins.
