Accumulation of Curcumin and its genetic variation in medicinal plant Curcuma species

比较不同栽培方式和不同品系姜黄的药用特性、姜黄素和挥发油在根茎中的积累，以评价姜黄属植物的质量和产量。姜黄素和挥发油的含量随着根茎的发育而增加，并与根茎产量密切相关。姜黄素和挥发油的提取率和含量基本上都是国外C.比国内C. longa遗传分析表明，姜黄素含量在不同品系间的差异主要是由于姜黄素含量的差异。longa是由外源C. longa和其他姜黄属物种。详细的系统分析，以阐明遗传联系。

Medicinal properties, curcumin and essential oil, accumulated in rhizomes were compared among different cultivations and different lines to evaluate the quality with the yield in Curcuma species. Contents of curcumin and essential oil increased with the development of rhizome, and closely related to rhizome yield. Higher rates and contents of curcumin and essential oil were basically observed in foreign C. longa than in domestic C. longa. Genetic analysis suggested that the difference of curcumin content among the various lines of C. longa was caused by hybridization and introgression between foreign C. longa and other Curcuma species. Detail system diagramwas made to elucidate genetic affiliation.
