title: Analysis of genetics and chemical contents relation compared to commonly used Cissus quadrangularis L. and barcode markers of some Thailand Cissus species.
abstract: Several Cissus species are commonly used as traditional and modified medicines, and their chemical constituents are major point for precise usage. However, C. quadrangularis is the only species for which the usages and the chemical composition have been reported. These data should be investigated for other species in the genus. Eight species namely C. assamica, C. carnosa, C. elongata, C. hastata, C. javana, C. pteroclada, C. quadrangular is and C. repens were evaluated for genetic relationships and chemical composition. Constructed dendrogram shows high-powered efficiency of inter-simple sequence repeat (ISSR) data used which can clearly identify different and identical species. Genetic similarity (S) value of the identical species is 0.86, whereas for different species the value can vary from 0.53 to 0.75. Four highly related species (S=0.64-0.72), C. assamica, C. carnosa, C. hastata and C. repens were selected to undergo chemical study by gas chromatography-mass spectrometry (GC-MS) on the methanol crude extract. Only one compound, β-sitosterol, found in the four species is identical to the compound reported from C. quadrangular is, where there were five identical chemicals found in the selected species. Species-specific barcode with rbcL region was constructed. Nucleotide variation was evaluated indicating genetic distance value of 0.025 to 0.072.
