BACKGROUND
Turmeric is a rich source of bioactive compounds useful in both medicine and cuisine. Mineral concentrations effects (PO43-, Ca2+, Mg2+, and KNO3) were tested during in vitro rhizome development on the ex vitro content of volatile constituents in rhizomes after 6 months in the greenhouse.
Optimization of GC-MS conditions based on resolution and stability of analytes for simultaneous determination of nine sesquiterpenoids in three species of Curcuma rhizomes.

Logi sisse
GC-MS is a powerful tool for analysis of volatile oil, and resolutions of analytes were exclusively used as marker for optimization of the conditions. However, volatile oil usually contains heat labile components which may degrade and result in wrong results during GC analysis. In present study,
