Pharmacognostic Specification of Cyclea Barbata Roots

Abstract

The morphology and histology of the roots of Krung Kha Mao or Cyclea barbata (Wall.) Miers (Menispemaceae) were studied and illustrated. Pharmacognostic specification were performed by studying of chromatographic patterns of chemical constituents, both one-dimensional and two-dimensional TLC, with a view to bring out the diagnostic characters of the drug. Loss on drying, ash content, moisture content and extractive values represent the specification of this particular species. In additional, the quantitative analysis by thin-layer chromatographic densitiometry method and capillary electrophoresis method using (+)- tetrandrine as a marker is reported.
