Qualitative Estimation of Bioactive Compound Present in Centella Asiatica: An Important Medicinal Plant

Abstract

Abstract-Qualitative phytochemical analysis of this plant confirms the presence of various phytochemicals like alkaloids, flavonoids, tannins, terpenoids, saponin, steroids, and proteins, reducing sugars, carbohydrates and cardiac glycosides in its methanolic extracts. This paper deals with the significance of these phytochemicals with respect to the role of these plants in traditional medicinal system. This preliminary study draws attention to the need for further studies of the active principles identified in the reported species for the treatment of many diseases in order to understand their mode of action in controlling diseases.

“…Similarly, standard phytochemical screening was performed for the detection of flavonyl glycosides, lipids and flavanoids (Singh et al . ).…”

“…) was used for the detection of steroids; sulphuric acid test (Firdouse and Alam ) was used for the detection of quinines; ferric chloride test (Firdouse and Alam ) was used for the detection of phenols; biuret, ninhydrin and Bradford assays (Singh et al . ) were used for the detection of proteins. Similarly, standard phytochemical screening was performed for the detection of flavonyl glycosides, lipids and flavanoids (Singh et al .…”

Antioxidant and α-glucosidase inhibitory activities of constituents from Euonymus alatus twigs

“…Many studies have showed that biological activities of phytochemicals are comparable to previous synthetic compounds, and they have very low side effects. The most important bioactive constituents of plants include alkaloids, tannins, steroids, terpenoids, flavonoids, and phenolic compounds (Singh et al, 2012).…”

“…Crude extracts of cassava and fern leaves were prepared by boiling method (Bakhtiar et al, 1994) and those of pegagan, fruit pericarp of mangosteen and stem bark of A. scholaris by macerated with methanol (Singh et al, 2012;Orozco and Failla, 2013).…”

“…Groups of secondary metabolites potentially developed as biostimulants are mostly found in tropical plants like in leaves of cassava (Manihot esculenta) and fern (Gleichenia linearis) containing flavonoid (Bakhtiar et al, 1994), fruit pericarp of mangosteen (Garcinia mangostana) containing xanton (phenolic) (Orozco and Failla, 2013), stem bark of Alstonia scholaris containing alkaloid (Marliana and Ismail, 2011), and Centella asiatica containing terpenoid (Singh et al, 2012).…”
