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.

Background: Mollugo oppositifolia, is one of the plants commonly used as, \‘Parpata\’ by Ayurvedic practitioners. It is indicated as a bitter tonic, antiseptic and febrifuge. Aim: To generate and ensemble data of physical parameters for ascertaining the identification and to develop validated HPTLC method for quantification of oleanolic acid and lupeol in M. oppositifolia. Materials and Methods:M. oppositifolia was studied for establishing pharmacognostic standards including macro and microscopical characters, physico-chemical analysis and quantification of oleanolic acid and lupeol by HPTLC method. Results: It is an annual, prostrate herb with linear-lanceolate leaf and white coloured flower. Microscopically root can be characterized by crescent shaped phloem associated with continuous or discontinuous rings of xylem; stem by epidermis bearing multi-cellular simple and glandular trichomes, and sclerenchymatous pericycle; and leaf by continuous band of a palisade cells and rosettes and prisms of calcium oxalate throughout parenchyma. Powdered drug can be typified by multi-cellular trichomes, fragments of epidermis of leaf in surface view, epidermis of corolla and entire or broken seeds. Saponins and flavanoids were found be the major components. HPTLC method was developed for quantification of oleanolic acid and 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. The amount of oleanolic acid and lupeol were found to be 0.027-0.029\% w/w and 0.015-0.016\% w/w respectively. Conclusion: The quality parameters and HPTLC method developed would serve as useful gauge in standardization of Mollugo oppositifolia.
