Diabetes mellitus type 2 is a metabolic disorder characterized by hyperglycemia including insulin resistance and relative lack of insulin. Type 2 diabetes is expected to reduce ten-year-shorter life expectancy. In this research article, we have isolated two terpenoids from the stem bark of Syzygium alternifoliumby column chromatography.The isolated compounds were identified as friedelin and 3β-...

Phytochemical analysis of Cymbopogon citratus revealed presence of bioactive compounds such as alkaloids, flavonoids, saponins, tannins, phenols, terpenoids etc. Each of the bioactive compounds were estimated and isolated separately by solventsolvent extraction for methanolic and aqueous extracts of Cymbopogon citratus. Saponins content was higher in methanolic extracts of Cymbopogon citratus (...

In order to analyze whether the reducing redox status and activation of thioredoxin reductase (TRR)/thioredoxin(TRX) system induced by oligo-carrageenan (OC) kappa in Eucalyptus globulus activate secondary metabolism increasing terpenoid synthesis, trees were sprayed on the leaves with water, with OC kappa, or with inhibitors of NAD(P)H, ascorbate (ASC) and (GSH) synthesis and TRR activity, CHS...

The aerial parts of Achillea setacea afforded, in addition of a rare monoterpene triol and 12 known sesquiterpene lactones, a new guaianolide containing an endoperoxide ring. Its structure was elucidated by spectral methods.

Terpenoids, or isoprenoids, are a family of compounds with great structural diversity which are essential for all living organisms. In cyanobacteria, they are synthesized from the methylerythritol-phosphate (MEP) pathway, using glyceraldehyde 3-phosphate and pyruvate produced by photosynthesis as substrates. The products of the MEP pathway are the isomeric five-carbon compounds isopentenyl diph...

This work reviews the production of terpenoids by endophytic fungi and their biological activities, in period of 2006 to 2010. Sixty five sesquiterpenes, 45 diterpenes, five meroterpenes and 12 other terpenes, amounting to 127 terpenoids were isolated from endophytic fungi.

Alkaloids, tannins, saponins, steroids, terpenoids and flavonoids distribution in n-hexane and aqueousmethanolic extract of kalanchoe laciniata was assessed and compared. The present study was carried out to study the phytochemical constituents of Kalanchoe laciniata. Aqueous-methanol and n-hexane were the solvents used for the extraction of the plant. Phytochemical analysis was carried out on ...

The transcription factor, nuclear factor kappa B (NF-kB) is one of the principal inducible protein in mammals known to control the gene expression in many critical physiological responses such as oxidative stress, inflammation etc. and has been shown to play an important role in the pathogenesis of cancer. Terpenoids are major constituents present in nutritionally used fruits, vegetables and di...

Urinary tract infection by Proteus mirabilis depends on several virulence properties that are coordinately regulated with swarming differentiation. Here we report the antibacterial and anti-swarming effect of seventeen terpenoids, and the effect of subinhibitory concentrations of five selected terpenoids on swarming, biofilm formation and haemolysin activity. The results showed that all the ter...
