Introduction: Euryale ferox Salisb. popularly called {\textquotedblleft}Foxnut{\textquotedblright} is a spiny aquatic plant locally named {\textquotedblleft}Thangjing{\textquotedblright} in Manipur and is one of the most highly consumed aquatic crops while Eupatorium birmanicum DC. locally named {\textquotedblleft}Langthrei{\textquotedblright} is an endemic ethnomedicinal plant found in Manipur, India. Methods: This study was carried out to examine the phytochemical content, evaluate the Total Phenolic Content (TPC), Total Flavonoid Content (TFC) and the in vitro antioxidant potential (DPPH and ABTS assays) in the seeds, arils of E. ferox and leaves of E. birmanicum. Results: Phytochemicals such as phenols, flavonoids, saponins, tannins, alkaloids and steroids were detected from the plant samples studied. Among the samples, TPC was found in the range 21.95 {\textpm} 1.18 mgGAE/g ext to 119.80 {\textpm} 2.63 mgGAE/g ext while, TFC was recorded in the range 2.57 {\textpm} 0.07 mgQE/g ext to 7.27 {\textpm} 0.28 mgQE/g ext with the highest value of TPC and TFC in E. ferox seeds. In case of DPPH and ABTS assays, the recorded IC50 value were attained in the range 16.99 {\textpm} 0.49 μg/mL to 335.90 {\textpm} 2.19 μg/mL and 70.69 {\textpm} 1.83 μg/mL to 576.26 {\textpm} 4.41 μg/mL respectively with the lowest IC50 value recorded in E. ferox seeds. Conclusions: The results of our study revealed that seeds and arils of E. ferox as well as leaves of E. birmanicum contain a variety of phytochemicals and promising antioxidant activity which will contribute a scientific insight for exploration of their therapeutic potentials in the future.

Background: In ethno-medicinal practices, the leaves of Alocasia macrrorhizos, Canavalia ensiformis, Amaranthus cruentus, Averrhoea carambola, Bauhina tenifloara\ and Capsicum Chinese have different pharmacological activities. The problem encountered with the proper utilization of herbal drugs is lack of documentation and standard parameter, which create problem in acceptance and importance of these plants. Objective: The objectives of our study are to establish scientifically evaluated pharmacognostic profile and in vitro antiinflammatory screening of six plants. Methods: Leaf sample from each plant was evaluated by macroscopic, microscopic and physicochemical parameters (As per WHO recommended methods of standardization). The anti-inflammatory activity screening of methanolic extracts was carried out against inhibition of protein denaturation method taking diclofenac sodium as a benchmark. Results: The macroscopic characteristic and microscopical evaluation reveals the type of stomata within the leaves and presence of parenchyma cells, collenchyma cells, upper epidemis, lower epidermis, vascular bundle, palisade cells and trichomes in the transverse section of leaves. Physicochemical parameter reveals the total ash, acid insoluble ash, water soluble, methanol soluble extractives and moisture content. The IC50 value of MEAM, MECE, MEAC, MEAC1, MECC\ and MEBT against inhibiton of protein denaturation was found to be 72.88, 841.78, 735.12, 303.75, 188, and 354.1855 μg/mL respectively. Conclusion: The present study contributes useful information that will help in the exact identification as well as assessment of purity of crude drugs. Methanolic extract of Alocasia macrorrhizos could be a potential anti-inflammatory agent from the natural sources.
