Analysis of Antioxidant Activity from Mentha arvensis Extracts by DPPH Method

/in /by

The present study was focused on antioxidant activity of Mentha arvensis L. Antioxidant activity was determine from different solvent extracts of Mentha arvensis L. The Ethanol extract show highest 86.98 % DPPH scavenging activity than other solvent extract. The screening tests also were performed for the presence of secondary metabolites such as alkaloids, flavonoids, terpenoids, phenols, steroids, saponins and tannins in the extracts. It is concluded that the ethanolic extract has potential bioactive compounds.

Pharmacological Studies on Dregea Volubilis and Derris Trifoliate – The Medicinal Plants

/in /by

The present work aims to study the pharmacological studies such as physico-chemical and phytochemical screening on Dregea volubilis and Derris trifoliate. The samples were collected, washed, dried in hot air oven and were grinded to form fine powder. Both the powders were subjected to various physic-chemical tests such as ash value, water soluble ash, acid insoluble ash and loss on drying. Solvent optimization was carried out and it was found that water and organic solvent Methanol showed best extractive values. Further Methanolic extract was subjected to phytochemical screening which showed the presence of carbohydrates, alkaloid, flavonoids, tannins and phenols were present in both the plants.

Saponins were only present in Dregea volubilis plant powder.
