Use of Kñéravidäré As a Substitute for Vidäré As Per Ayurvedic Descriptions Indian Journal of Traditional Knowledge Vol. 8(3), July 2009, pp. 310-318 Use of Kñéravidäré as a substitute for Vidäré as per Ayurvedic descriptions Padma Venkatasubramanian*, Subrahmanya Kumar K & SN Venugopal Foundation for Revitalisation of Local Health Traditions, No 74/2, Jarakabande Kaval, Post Attur, via Yelahanka, Bangalore 560 064, Karnataka E-mail: [email protected] Received 6 November 2007 revised 22 October 2008 The classical texts of Ayurveda incorporate multiple names for most of the plant drugs described for their medicinal use. As a result, the correct identification of related botanical source, many a times, becomes ambiguous. Extensive background work on nomenclature correlation can be assumed in the scholarly works of several authors of twentieth century including those of the official formularies and pharmacopoeias of Ayurveda of India. However, the works do not describe the research methodology and findings that led to the correlations. There is an urgent need to revisit this issue systematically and to publish the same through books and articles in peer-reviewed journals. Owing to several reasons, including availability of the required plant raw drugs, there are controversies relating to use of more than one botanical entity by the Ayurvedic manufacturing units. Vidäré ( ivdarI ) is one such example where at least four different botanical entities have been recorded in use by the industry. Pueraria tuberosa (Roxb. ex Willd.) DC. is the only accepted candidate for Vidäré as per official pharmacopoeias. Kñéravidäré (]IrivdarI ), a well documented type of Vidäré as per the classical Ayurveda texts, finds no mention as Vidäré in these pharmacopoeias. The study, through etymological analysis of Sanskrit synonyms, formulations and verses, indicates that two distinct botanical entities were used as Vidäré , even during the period of Caraka . Both these entities have been described as having similar properties and actions, thus making them eligible to be used as substitutes of one another. The two botanical entities that merit acceptance as sources of the classical Ayurvedic plant drug Vidäré are Pueraria tuberosa (Roxb. ex Willd.) DC. and Ipomoea mauritiana Jacq., though the later is better known as Kñéravidäré . Keywords : Ayurveda , Medicinal plant, Synonyms, Vidäré, Kñéravidäré IPC Int.

HEARN Department of Ecology and Evolutionary Biology, University of Arizona, Tucson, Arizona 85721, USA ([email protected]) ABSTRACT To understand evolutionary patterns and processes that account for anatomical diversity in relation to ecology and life form diversity, anatomy of storage roots and stems of the genus Adenia (Passifloraceae) were analyzed using an explicit phylogenetic context. Over 65,000 measurements are reported for 47 quantitative and qualitative traits from 58 species in the genus. Vestiges of lianous ancestry were apparent throughout the group, as treelets and lianous taxa alike share relatively short, often wide, vessel elements with simple, transverse perforation plates, and alternate lateral wall pitting; fibriform vessel elements, tracheids associated with vessels, and libriform fibers as additional tracheary elements; and well-developed axial parenchyma. Multiple cambial variants were observed, including anomalous parenchyma proliferation, anomalous vascular strands, successive cambia, and a novel type of intraxylary phloem.

Thus, a replacement of these synthetics by antioxidant extractions from various foods has been proposed. More than 8000 different phenolic compounds have been characterized; fruits and vegetables are the prime sources of natural antioxidants. In order to extract, measure, and identify bioactive compounds from a wide variety of fruits and vegetables, researchers use multiple techniques and methods. This review includes a brief description of a wide range of different assays. The antioxidant, antimicrobial, and anticancer properties of phenolic natural products from fruits and vegetables are also discussed. Keywords: antimicrobial; antioxidants; medicinal plants; BHT 1. Introduction Many antioxidant compounds can be found in fruits and vegetables including phenolics, carotenoids, anthocyanins, and tocopherols [1]. Approximately 20% of known plants have been used in pharmaceutical studies, impacting the healthcare system in positive ways such as treating cancer and harmful diseases [2].

    Identification of Invasive Alien Species using DNA barcodes Royal Belgian Institute of Natural Sciences Royal Museum for Central Africa Rue Vautier 29, Leuvensesteenweg 13, 1000 Brussels , Belgium 3080 Tervuren, Belgium +32 (0)2 627 41 23 +32 (0)2 769 58 54 General introduction to this factsheet The Barcoding Facility for Organisms and Tissues of Policy Concern (BopCo) aims at developing an expertise forum to facilitate the identification of biological samples of policy concern in Belgium and Europe. The project represents part of the Belgian federal contribution to the European Research Infrastructure Consortium LifeWatch. Non-native species which are being introduced into Europe, whether by accident or deliberately, can be of policy concern since some of them can reproduce and disperse rapidly in a new territory, establish viable populations and even outcompete native species. As a consequence of their presence, natural and managed ecosystems can be disrupted, crops and livestock affected, and vector-borne diseases or parasites might be introduced, impacting human health and socio-economic activities. Non-native species causing such adverse effects are called Invasive Alien Species (IAS). In order to protect native biodiversity and ecosystems, and to mitigate the potential impact on human health and socio-economic activities, the issue of IAS is tackled in Europe by EU Regulation 1143/2014 of the European Parliament and Council. The IAS Regulation provides for a set of measures to be taken across all member states. The list of Invasive Alien Species of Union Concern is regularly updated. In order to implement the proposed actions, however, methods for accurate species identification are required when suspicious biological material is encountered.

  • Abstract PARSING POLYPHYLETIC PUERARIA: DELIMITING DISTINCT
    Abstract PARSING POLYPHYLETIC PUERARIA: DELIMITING DISTINCT EVOLUTIONARY LINEAGES THROUGH PHYLOGENY by William Cagle May, 2013 Director: Dr. Ashley N. Egan DEPARTMENT OF BIOLOGY A taxon is defined as polyphyletic when it does not include the last common ancestor of all true members of the taxon, resulting in a number of subgroups not united by a common ancestor. Previous work has suggested Pueraria (Fabaceae) to be polyphyletic. Although several taxonomic treatments have recognized Pueraria as an unnatural grouping since its creation in 1825, and two have put forth taxonomic hypotheses, the polyphyly has never been resolved. The need for further biosystematic research has always been cited as the reason no changes were proposed. This project attempted to address this issue by sampling broadly across phaseoloid legumes with an initial target goal of 156 species including 15 species of Pueraria. Ultimately, 104 species across 69 genera were sampled for AS2 and 116 species across 64 genera for matK. Phylogeny reconstruction was carried out using maximum likelihood and Bayesian inference. Both analyses yielded congruent tree topologies and similar support values. Both previous taxonomic hypotheses show some congruence with the data, but discrepancies do occur. This work provides strong support for the existence of five separate clades within the genus Pueraria, requiring the resurrection of the genus Neustanthus for P. phaseoloides along with the need to create a new genus each for P. stricta, P. peduncularis, and P. wallichii.
