Lack of Pharmacological Basis of Substitution of An Original Article Lack of Pharmacological Basis of Substitution of an Endangered Plant Group “Ashtawarga”- A Significant Ingredient of Polyherbal Formulations Jaswinder Kaur Virk1, Vikas Gupta1, Sanjiv Kumar2, Ranjit Singh3 and Parveen Bansal*1 1University Centre of Excellence in Research, BFUHS, Faridkot, Punjab, India 2National Medicinal Plants Board, Department of AYUSH, New Delhi, India 3Shobhit University, Meerut, India ABSTRACT Objective: Ashtawarga plants have been included among 560 plants appearing in the red list of endangered species. To overcome problem of scarcity of endangered species Department of AYUSH, Govt. of India has permitted the substitution of rare herbal drugs with available substitutes on the basis of Ayurvedic concepts. Metadata analysis has been carried out to find out the basis of substitution of the original Ashtawarga plants by similar plants. Methods: The review on substitution of Ashtawarga plants was initiated by accumulating and analyzing the data presented on internet search engines, WHO and ancient Ayurveda texts Bhavaprakasha Nighantu, Sushruta Samhita and Charaka Samhita etc. In this review, Rasa, Guna, Virya Vipaka, Doshic (Rasapanchakas) and pharmacological actions of original Ashtawarga drugs and substitutes have been evaluated. Result: The investigation of review indicates that only forty percent Address for of total parameters of Rasapanchakas and pharmacological actions of Ashtawarga plants and their substitutes are similar whereas 60% of Correspondence total parameters do not match with each other. Dr. Parveen Bansal, Conclusion: Our survey reflects that basis of substitution of Joint Director individual herbs is neither based on pharmacological actions nor University Centre of based on Ayurvedic philosophy of drug action. It seems that Excellence in substitution of Ashtawarga plants is on the basis of some Guna- Research, BFUHS, Karma similarities which are not clinically effective. As the Faridkot, Punjab, India Rasapanchakas are inter- related to each other, so any change in Guna-Karma property shall alter the therapeutic action of the drug. E-mail: This basis of substitution has been found irrational and seems to play [email protected] with the eternity and medical importance of Ayurveda at International level.

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.

In the present study, those results were reexamined in molecular phylogenetic analyses using chloroplast DNA and nuclear DNA (ITS). Our molecular data show that Shuteria africana is sister to the genus Amphicarpaea, and that A. ferruginea is sister to A. edgeworthii and A. bracteata within the genus. For a consistent systematic treatment with the discrepancy between the results of the pollen morphology and the present molecular study, a new monotypic genus Afroamphica is proposed for Shuteria africana.

The acetone fraction showed the strongest 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging Keywords: activity among four fractions and was subjected to separation and Ipomoea mauritiana purification using preparative reverse-phase high-performance liquid Phenolics DPPH chromatography (HPLC). LC-ESI-MS Results : Two compounds were separated from the acetone fraction using preparative LC fraction collector. The purified compounds were screened for their antioxidative potential using DPPH assay. The compounds were subjected to LC-MS analysis in ESI negative mode. One of the compounds was identified as Caffeoyl glucose based on the mass fragmentation. Conclusion: The acetone fraction showed highest radical scavenging activity and the phytoconstituents of the same were identified by LC- MS/MS analysis.
