Test for diterpenes
: A small quantity of extract was dissolved in 3ml distilled water.
trilobata revealed the presence of phenolic compounds, anthracene derivatives, and mono-, sesqui-, and diterpenes
Heteroxenia ghardaqensis are rich in sesquiterpenoids, ceramides, diterpenes
, sterols and acylglycerols (Elshamy et al., 2015; Abdel-Razik et al., 2016) and possess many pharmacological activities such as antitumor nature, antiviral, antibacterial, anti-inflammatory, antifungal, antipyretic, hypoglycemic properties, protective effect against cadmium toxicity and antioxidant (Mohamed et al., 2012).
In this study, we illuminate the binding mode of pimarane diterpenes
(diaporthein A and diaporthein B) to the NMD-1 by molecular docking.
Yew contains a mixture of alkaloids known as taxine, diterpenes
, lignans and resin, it is toxic in all parts except the aril.
It was not just caffeine, but a mix of compounds including hydroxycinnamic acids notably chlorogenic acid, trigonelline, diterpenes
eg cafestol and kahweol, and caffeic acid, that is said to be the reason behind the link, said Mattias Carlstrom, Associate Professor from the Karolinska Institutet, Sweden.
-A number of potentially clinically relevant compounds are present in coffee, including: caffeine, hydroxycinnamic acids notably chlorogenic acid, trigonelline, diterpenes
eg cafestol and kahweol, and caffeic acid ( ANI )
A total of 14 classes of secondary metabolites were investigated, viz., alkaloids, anthocyanins, anthraquinones, flavonoids, coumarins, anthracene derivatives, lignans, mono-, sesqui-, and diterpenes
, naphthoquinones, saponins, water-soluble tannins, condensed tannins, xanthines, triperpenes and steroids.
The analysis in positive and negative ionization modes revealed the presence of 26 diterpenes
skeletons as major components, of which 17 were characterized (Table 1).
pallida consists of alkanes (21.37%), aromatic compounds (6.26%), ketones (47.66%), sesquiterpenes (10.06%), diterpenes
(5.9%), triterpenes (6.12%), accompanied by relatively smaller amounts of monoterpenes (1.16%) and fatty acids (0.88%).
The members of this family have a wide diversity of chemical compounds, including limonoids, triterpenes, steroids, diterpenes
, sesquiterpenes and coumarins (Cortez et al., 2000; Lago et al., 2000, 2002; Soares et al., 2012; Scur et al., 2016).
