Generally the medicinal plants consist of more phytochemicals and all of them are secondary metabolites. These phytochemicals have the ability to produce physiological changes on the human body. The phytochemicals have various complex substances. Keeping this view in mind the present investigation was carried out in Canthium parviflorum seed material in comparison with in-vitro leaf callus mate...

Isoprenoids (also referred to as terpenoids) are the largest group of natural products, comprising over 25,000 known compounds [1]. Each member of this class is assembled from 5-carbon (C5) isoprene units and derived metabolically from the basic building block isopentenyl pyrophosphate (IPP) and its isomer, dimethylallyl pyrophosphate (DMAPP). Subsequent metabolic reactions (such as cyclization...

Viburnum grandiflorum Wall. ex DC., is a plant of Himalaya and Hazara region of Pakistan which was screened for bioactive secondary metabolite and screen for biological activity. Preliminary phytochemical profiling indicated the presence of different classes of secondary plant metabolites such as alkaloids, terpenoids, saponins, anthraquinone. These secondary metabolites vary in types in differ...

Terpenoids were extracted from grape vine bunches during plant development and analysed by GC-MSD. The grapevines analysed were from a commercial harvest of Vitis vinifera cv. Shiraz. The terpenoids were analysed from 4 weeks post flowering (wpf) to harvest in one season. The data are presented with the structure of the compound and aroma profile and semi-quantified. The sub-class of sesquiterp...

Fruits produce a range of volatile compounds that make up their characteristic aromas and contribute to their flavor. Fruit volatile compounds are mainly comprised of esters, alcohols, aldehydes, ketones, lactones, terpenoids and apocarotenoids. Many factors affect volatile composition, including the genetic makeup, degree of maturity, environmental conditions, postharvest handling and storage....

Heterogeneous catalysis and their application in industrial-scale organic synthesis of fine chemicals are greatly facilitated by catalysis and further on by catalyst recovery and recycles to fits most “principles of green chemistry. In acid media, terpenoids generally undergoes various transformations. The terpenoid transformations include various liquid Bronsted and Lewis Acids, Acid clays, He...
