“…The contour pattern of the planoconvex type is also recorded in species of the family, as in Nicotiana glauca [23]. The angular collenchyma observed in the midrib, petiole and stem of N. physalodes was previously recorded for another genus of Solanaceae, such as Nicotiana [23], Solanum L. [31,32], and Hyoscyamus L [34].…”

Nicandra physalodes (L.) Gaertn is a sub-shrub used in folk medicine for various purposes, as it is also considered a toxic plant. Due to its ethnobotanical importance, a study of vegetative organs (leaves, stem, root) of this species was carried out, for its micromorphological and histochemical characterization, with the objective of finding parameters to support the taxonomy and quality control of their ethnodrugs. Paradermic and cross sections were carried out on fresh samples of leaves, stem and root, from the plant collected in the municipality of Bananeiras, State of Paraíba, Brazil, as well as histochemical tests with specific conductors, following the usual techniques in botanical anatomy. It was observed that N. physalodes has an amphistomatic leaf blade, anisocytic and anomocytic stomata, 1-serial epidermis, sinuous anticlinical cell walls, dorsiventral mesophyll, 1-serial palisade parenchyma and the 3-4-serial spongy border; biconvex midrib, bicolateral, arched; semicircular petiole with lateral, adaxial projections, 5-6-seriate collenchyma and vascular system similar to the midrib, 2 central bundles and 2 accessories in the lateral projections. The stem is irregularly pentagonal, epidermis 1-seriate, angular collenchyma 3-4-seriate, prismatic crystals are observed in the cortex and medullary parenchyma, and the vascular system is amphiphilic siphonostelic. The root is circular, with the endoderm 1-serial, siphonostelic vascular system. Histochemical tests showed a positive reaction for lipids, lignin, starch, alkaloids, phenolic compounds and proteins in the rib, petiole and stem. The anatomical character set of the leaf epidermis, stem and root together with the histochemical data are distinctive for N. physalodes, who support her taxonomy and the quality control of her ethnodrugs.

“…We found several molecules in herbs to have antitubercular effects. These are Petasites japonicus (John, 1977), Piper trichostachyon (Wagner & Wolff, 1977), Solanum torvum (Silva et al, 2011), Fritillaria przewalskii (Chang & Paul, 2001), Hernandia sonora (Udino et al, 1999) and Phyllanthus urinari (Nair & Abraham, 2008). In addition, many of the herbs have been shown to have hepatoprotective activities, which include Annona reticulata (Thattakudian Sheik Uduman, Sundarapandian & Muthumanikkam, 2011; Mohamed Saleem et al, 2008), Annona squamosa (Thattakudian Sheik Uduman, Sundarapandian & Muthumanikkam, 2011; Mohamed Saleem et al, 2008), and Camellia sinensis (Issabeagloo & Taghizadieh, 2012).…”

Background. Traditional Chinese medicine encompasses a well established alternate system of medicine based on a broad range of herbal formulations and is practiced extensively in the region for the treatment of a wide variety of diseases. In recent years, several reports describe in depth studies of the molecular ingredients of traditional Chinese medicines on the biological activities including anti-bacterial activities. The availability of a well-curated dataset of molecular ingredients of traditional Chinese medicines and accurate in-silico cheminformatics models for data mining for antitubercular agents and computational filters to prioritize molecules has prompted us to search for potential hits from these datasets.Results. We used a consensus approach to predict molecules with potential antitubercular activities from a large dataset of molecular ingredients of traditional Chinese medicines available in the public domain. We further prioritized 160 molecules based on five computational filters (SMARTSfilter) so as to avoid potentially undesirable molecules. We further examined the molecules for permeability across Mycobacterial cell wall and for potential activities against non-replicating and drug tolerant Mycobacteria. Additional in-depth literature surveys for the reported antitubercular activities of the molecular ingredients and their sources were considered for drawing support to prioritization.Conclusions. Our analysis suggests that datasets of molecular ingredients of traditional Chinese medicines offer a new opportunity to mine for potential biological activities. In this report, we suggest a proof-of-concept methodology to prioritize molecules for further experimental assays using a variety of computational tools. We also additionally suggest that a subset of prioritized molecules could be used for evaluation for tuberculosis due to their additional effect against non-replicating tuberculosis as well as the additional hepato-protection offered by the source of these ingredients.

“…20,21,22,23,24 Macroscopy involves the use of vegetative and or floral characters to discriminate the desired plant species and plant part or morphologically similar species that might be included in recipes as adulterants while microscopy relates to assessment of micromorphological characters. The macroscopic and microscopic description of C. prostrata given in this study is the first step towards proper identification and authentication of the plant for purity.…”

Background: Cyathula prostrata (Blume) L. from the family Amaranthaceae has been used traditionally for rheumatism, dysentery, wounds and urethral discharges in the tropical regions of the world. Aim: The present study was undertaken to perform quality control standardization and to evaluate antioxidant activity of the leaf, stem, root and the whole plant of Cyathula prostrata. Methods: Macroscopic and microscopic evaluations were carried out on the plant using standard procedures. Powdered sample of the leaf was evaluated with various organic solvents for fluorescence. The chloroform, ethyl-acetate and methanolic extracts of the leaf, stem, root and whole plant were subjected to various pharmacognostic analyses and evaluated for in vitro antioxidant activity using DPPH assay.Further, thin layer chromatoghraphy was used to evaluate the chloroform extract. Results: Important epidermal features in the plant include: coastal cells, unbranched, uniseriate, multicellular and non-glandular trichomes. Leaves are amphistomatic showing mostly anomocytic and actinocytic stomata. Starch grains are restricted to the adaxial surface. Vascular bundles are mainly collateral and well-developed bundle sheath. The transverse section of stem is circular, hypodermis (1-3 layers). Cross section of the root is described in detail for the plant. Cortex has angular cells. Fluorescence studies showed different colours. Physico-chemical results are comparable with standards. The TLC profile showed presence of at least seven compounds in the leaf, root and the whole plant extracts, while nine components were obtained from the stem extract. The ethyl acetate extract of the root and ethanol extract of the stem gave the highest phenolic contents (30.09±3.768 mg GAE/g) and DPPH free radical scavenging activity (87.0 ± 0.208), respectively. Conclusion: The distinctive features established in this study are steps in identification, standardization and quality control of this medicinal plant.
