To study the genetic diversity of Pinellia ternata. on the chemical composition.
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.
The difference in contents of beta-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.
研究半夏在化学成分方面的遗传多样性。
收集了主要源自长江中下游流域的15个半夏种群，并在南京农业大学卫岗实验农场相同栽培条件下进行种植，持续比较了从这些种群块茎中提取的三种指标性化学物质的含量。
观察到从种群块茎中提取的β-谷甾醇、缬氨酸和精氨酸含量存在差异，且这些含量也随收获时间而不同。但秋季这三种化学物质各自的平均含量均分别高于夏季。
