  • embedding leaf tissue in graphene ink to improve signals in electrochemistry based Chemotaxonomy
    Electrochemistry Communications, 2018
    Co-Authors: Li Fu, Yuhong Zheng, Pengchong Zhang, Haoyang Zhang, Luxi Zhang, Weitao Su
    Abstract:

    Abstract We propose a method for the electrochemical identification of plants by embedding leaf tissue into graphene deposited on a screen-printed electrode (SPE). The embedding process significantly enhanced the electrochemical signals, which made the SPE sufficiently sensitive to record information about electro-active compounds in plants. In this work, five Lycoris herbs have been used as examples to evaluate the feasibility of the proposed technique. Multidimensional pattern recognition was successfully established for plant identification. In addition, the recorded “electrochemical fingerprints” provided valuable taxonomic information, demonstrating the enormous potential of the technique for plant Chemotaxonomy.

  • phytochemical and biological research of fritillaria medicine resources
    Chinese Journal of Natural Medicines, 2013
    Co-Authors: Dacheng Hao, Peigen Xiao, G U Xiaojie, Yong Peng
    Abstract:

    The genus Fritillaria is a botanical source for various pharmaceutically active components, which have been commonly used in traditional Chinese medicine for thousands of years. Increasing interest in Fritillaria medicinal resources has led to additional discoveries of steroidal alkaloids, saponins, terpenoids, glycosides and many other compounds in various Fritillaria species, and to investigations on their Chemotaxonomy, molecular phylogeny and pharmacology. In continuation of studies on Fritillaria pharmacophylogeny, the phytochemistry, Chemotaxonomy, molecular biology and phylogeny of Fritillaria and their relevance to drug efficacy is reviewed. Literature searching is used to characterize the global scientific effort in the flexible technologies being applied. The interrelationship within Chinese Bei Mu species and between Chinese species, and species distributed outside of China, is clarified by the molecular phylogenetic inferences based on nuclear and chloroplast DNA sequences. The incongruence between Chemotaxonomy and molecular phylogeny is revealed and discussed. It is essential to study more species for both the sustainable utilization of Fritillaria medicinal resources and for finding novel compounds with potential clinical utility. Systems biology and omics technologies will play an increasingly important role in future pharmaceutical research involving the bioactive compounds of Fritillaria.

  • chemical and biological research of clematis medicinal resources
    Chinese Science Bulletin, 2013
    Co-Authors: Dacheng Hao, Peigen Xiao, Yong Peng
    Abstract:

    Clematis is a botanical source for various pharmaceutically active components, which has long been used in conventional medicine since the beginning of Chinese civilization. Increasing interest in Clematis medicinal resources has led to additional discoveries of triterpenoid saponins, flavonoids, coumarins, alkaloids and many other compounds in various Clematis species, and to investigations on their Chemotaxonomy, molecular phylogeny and pharmacology. In continuation with our studies on Clematis chemistry and biology, we review the chemistry, Chemotaxonomy, molecular biology and phylogeny of Clematis and their relevance to drug efficacy and drug development. Various databases and technology have been used in literature search in order to characterize the global scientific effort. It is essential to study more species for both the sustainable utilization of Clematis medicinal resources and finding novel compounds with potential clinical utility. Systems biology and omics technologies will play an increasingly important role in future medicinal research involving bioactive compounds of Clematis.

  • research progress in the phytochemistry and biology of ilex pharmaceutical resources
    Acta Pharmaceutica Sinica B, 2013
    Co-Authors: Dacheng Hao, Peigen Xiao, Zhanguo Liang, Yong Peng
    Abstract:

    Abstract Ilex is a botanical source for various health-promoting and pharmaceutically active compounds that have been used in traditional Chinese medicine and food for thousands of years. Increasing interest in Ilex pharmaceutical and food resources has led to additional discoveries of terpenoids, saponins, polyphenols (especially flavonoids), glycosides, and many other compounds in various Ilex species, and to investigation of their Chemotaxonomy, molecular phylogeny and pharmacology. In continuation of our studies on Ilex pharmacology and phylogeny, we review the phytochemistry, Chemotaxonomy, molecular biology and phylogeny of Ilex species and their relevance to health-promotion and therapeutic efficacy. The similarity and dissimilarity between Ilex paraguariensis , the source plant of mate tea, and the source plants of large-leaved Kudingcha (e.g., Ilex kudingcha and Ilex latifolia ) are discussed. It is essential to utilize emerging technologies in non- Camellia tea studies to promote the sustainable utilization of Ilex resources and the identification and development of novel compounds with potential health and clinical utility. Systems biology and “-omics” technologies will play an increasingly important role in pharmaceutical and food research on the bioactive compounds of Ilex species.
