Abstract:
Obective: To study the genetic diversity of Pinellia ternata. on the chemical composition. Method: Fifteen populations of Pinellia ternata. originated mostly from middle and lower reaches of Yangtze River valley were collected and cultivated in Weigang Experimental Farm of Nanjing Agricultural University with same cultural conditions, and contents in three types of index chemicals extracted from tubers of the populations have been compared continuously. Result and conlusion: The difference in contents of β-sitosterol and Val and Arg extracted from tubers of the populations has been observed, and those contents are also different with harvesting time. But the mean contents of each of the three types of chemicals in autumn are all higher than those in summer respectively.
