In India, many indigenous plants are used in herbal medicine to cure diseases and heal injuries. Major pharmaceutical companies are currently conducting extensive research on plant materials gathered from the rain forests and other places for their potential medicinal value. Toddalia asiatica (L.) Lam. (Rutaceae) is widely used as a folk medicine in India. The roots are used in the treatment of indigestion and influenza and the leaves to treat lung diseases and rheumatism. The root and its bark have been used to treat fever, malaria, cholera, diarrhoea and rheumatism 1. Despite the use of this plant for such purposes, there is little information on the biochemical composition of Toddalia asiatica.  L.Var . floribunda.. This work is therefore aimed at documenting the biochemical compositions of Toddalia asiatica. L. Var . floribunda. From the earlier reports qualitative phytochemical results reveals that the methanolic stem extract of Toddalia asiatica.L. contain secondary metabolites like  Alkaloids, Flavonoids, Saponins, Steroids, Glycosides, Tannins. From the quantification result of various biochemical and phytochemical constituents like carbohydrates, proteins, total ascorbic acid, phenols, tannins and flavanoids content, it was noted that alkaloid found to be the highest with phenol as the next active constituents among the secondary metabolites in the stem. From the results it reveals Toddalia asiatica has the potential to be represented as an effective biochemical and therapeutic constituent for the future use in the medical field.

To evaluate phytochemical constituents and antioxidant potential of methanol aerial parts (leaf and stem) extract of Mentha arvensis L from Kashmiri Himalaya region. The extract shows the presence of flavonoids, saponins, alkaloids, steroids, carbohydrates, proteins, tannins and phenolics. The antioxidant activity of methanol aerial extract of Mentha arvensis L was evaluated by using 1,1-diphenyl, 2-picrylhydrazyl (DPPH) scavenging and reducing power assays. The total phenolic and total flavonoid content (mg/g) was found to be 672.11 and 283.1 respectively. The percentage inhibition of DPPH scavenging was found to be 81.33% at concentration of 0.5mg/ml. The reducing power was found to be 0.76 at 0.1mg/ml and increased to 2.42 at 0.5mg/ml. The results obtained revealed that methanol extract from aerial parts of Mentha arvensis L can be promising candidates for natural sources of antioxidants with high activity.
