ZHANG Xue, GAO Ya, YANG Xiao-han, et al. Pharmacognostical Identification and Molecular Pharmacognostical Identification on a New Adulterant of Clematidis Radix et Rhizoma[J]. Chinese journal of experimental traditional medical formulae, 2018, 24(14): 20-23. DOI: 10.13422/j.cnki.syfjx.20181411.
Objective: Research on a new adulterant of Clematidis Radix et Rhizoma was made by the ideas and methods of pharmacognosy and molecular pharmacology
in order to provide the basis for safe use of this herb. Method: The characters
microscopy and other pharmacognostic studies were performed on Clematidis Radix et Rhizoma and its adulterant
the characteristics of pharmacognostic identification of Clematidis Radix et Rhizoma and its adulterant were described.DNA in samples was extracted
internal transcribed spacer(ITS) sequences were amplified by polymerase chain reaction(PCR) and analyzed by ContigExpress.The ITS sequences was calculated the similarity according to the ITS sequences of National Center for Biotechnology Information(NCBI) database. Result: Pharmacognostic identification characteristics of Clematidis Radix et Rhizoma and its adulterant were skin color and the existence of the stem nodes
etc;the difference in their microscopic characteristics of transverse section was the existence of the pith.The molecular pharmacognostic studies showed the adulterant of Clematidis Radix et Rhizoma was Ardisiae japonicae sourced from Myrsinaceae. Conclusion: This adulterant of Clematidis Radix et Rhizoma is the stem and rhizome of A. japonicae. A. japonicae differs from Clematidis Radix et Rhizoma in terms of composition and function
so we should strictly distinguish them in clinical application.
