It refers to the extraction, screening and identification of the medicinally active substances found in plants. Some of the bioactive substances that can be derived from plants are flavonoids, alkaloids, carotenoids, tannin, antioxidants and phenolic compounds.
Thereof, how do you do a phytochemical analysis?
Qualitative and quantitative analysis of phytochemicals can be done using Gas Chromatography- Mass Spectroscopy (GCMS). GCMS can be applied to solid, liquid and gaseous samples. First the samples are converted into gaseous state then analysis is carried out on the basis of mass to charge ratio.
- Polyphenols – subcategorised as the flavonoids, phenolic acids and other non-flavonoid polyphenols.
- Terpenoids – subcategorised as the carotenoids and non-carotenoid terpenoids.
- Thiols – includes the glucosinolates, allylic sulfides and non-sulfur containing indoles.
Secondly, what is phytochemical analysis in plant?
Medicinal plants have bioactive compounds which are used for curing of various human diseases and also play an important role in healing. … The aqueous extract of leaf samples were used for the phytochemical analysis to find out the phytochemical constituents in the plants.
What is preliminary phytochemical screening?
Objective: Preliminary screening of phytochemicals is a valuable step, in the detection of the bioactive principles present in medicinal plants and subsequently may lead to drug discovery and development. … Results: All the selected medicinal plants were found to contain tannins and flavonoids.
What is the meaning phytochemical?
Phytochemicals are defined as bioactive nutrient plant chemicals in fruits, vegetables, grains, and other plant foods that may provide desirable health benefits beyond basic nutrition to reduce the risk of major chronic diseases (Liu, 2004).
Why do we do phytochemical analysis?
The phytochemical research approach is considered effective in discovering bioactive profile of plants of therapeutic importance. … Phytocompounds such as Alkaloids, Tannins, Saponins, Phenols, Flavonoids and Terpenoids are observed to be present in the investigated plants in variable proportions.
