North-eastern India is having rich biodiversity. Phytochemical are non-nutritive, chemical compounds occurs naturally on plants during metabolic processes and they have diverse proactive properties or disease preventive properties. Plants are known to produce these chemicals to protect them. While recent research demonstrates that they can also play an important role in protecting humans against diseases. Even some of these plants are in use as traditional medicine for centuries. Methanol extract showed the presence of most phytochemicals. Distilled water and acidified water extracts showed moderate phytochemical diversity. Ether extract showed presence of lipophilic phytochemicals like lipids, steroids, terpenoids, and triterpenoids. The TPC values for Clitoria ternatea range from 50-350 mg GAE/g. The methanolic extract of Clitoria ternatea showed higher total phenolic content of 209.2 mg GAE/g compared to the aqueous extract, which shows 122.1 mg GAE/g. The results indicate that methanol is a more efficient solvent for extracting phenolic compounds from Clitoria ternatea. The inorganic composition of plants, in a solid state, was determined using ED-XRF. The amount of silver, barium, cadmium, chromium, iron, nickel, lead, zinc, calcium, potassium, sodium, magnesium in plants were determined using ICP-OES. The most significant findings in this section include high concentrations of Potassium (K) in Asian pigeonwings followed by Calcium (Ca). According to the toxicity level, Cadmium (Cd) and Lead (Pb) levels are within safe limits. Hence, further research should be carried out to identify the active biomolecules or Phyto-molecules from the plants and determine the effects of them in vitro as well as in vivo.
