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.

Background: Rungia repens is one of the plants cited as \‘Parpata\’ in Ayurvedic literature and indicated as febrifuge, antitussive and vermifuge. Aim: To generate and ensemble data of physical parameters for ascertaining the identification and develop validated HPTLC method for quantification of kaempferol in R. repens. Materials and Methods: R. repens was studied for establishing pharmacognostic standards including macro and microscopical characters, physico-chemical analysis and quantification of kaempferol by HPTLC method. Results: It is a small, much branched, prostrate or sub-erect herb with lanceolate leaf and violet flowers. Microscopically root can be characterized by collenchymatous phloem associated with wide lignified xylem; stem by epidermis with simple and glandular trichomes and collenchymatous hypodermis; and leaf by epidermis embedded with cystoliths and bearing covering and glandular trichomes. Powdered drug can be typified by cystoliths, trichomes of aforementioned type, pollen grains and fragments of cork. Further studies revealed that brunt of heavy metal and microbial load in plant material was within permissible limits. Flavonoids and phenolics were found be major components. HPTLC method was developed for quantification of kaempferol using precoated silica gel plates as a stationary phase, and toluene: ethyl acetate: dichloromethane: formic acid: methyl ethyl ketone (5: 1: 1.5: 0.5: 0.8) as a mobile phase and scanning the plate at 254 nm. Conclusion: The distinctive quality profile data and validated HPTLC method tailored for Rungia repens using kaempferol as a marker, would aid as expedient measures for its evaluation.

Background: Polycarpaea corymbosa is one of the plants cited as \‘Parpata\’ in Ayurvedic literature and indicated for boils, inflammatory swellings, and ulcers. Aim: The present study is an attempt to generate and encompass the data of physical parameters for ascertaining the identification and develop a validated HPTLC method for quantification of lupeol in P. corymbosa. Materials and Methods: The whole plant was studied for establishing pharmacognostic standards including macro and microscopical characters, physico-chemical analysis and quantification lupeol by HPTLC method. Results: It is a small, much branched, erect or spreading herb with linear leaf and silvery-white cymes. Microscopically root can be connoted by continuous or discontinuous concentric rings of xylem and phloem; stem by papillose epidermis with multicellular branched collapsed and glandular trichomes, sclerenchymatous pericycle and hollow pith; and leaf by numerous collateral meristele enclosed within parenchymatous bundle sheath. Further studies evinced that brunt of heavy metal and microbial load in plant material was within permissible limits. Flavonoids, phenolics and saponins were found be major components. HPTLC method was developed for quantification of lupeol using precoated silica gel plates as a stationary phase, and toluene: methanol (9.4: 0.6) as a mobile phase and scanning the plate at 545 nm. Conclusion: The information demonstrated on pharmacognostic parameters and validated HPTLC method for estimation of lupeol for Polycarpaea corymbosa, would aid as coherent measures for its assessment.
