Representative extracted ion chromatograms of m/z 74 of mixed standards and methyl ester of fatty acids in tuberous roots (A) and rhizomes (B) derived from C. wenyujin, C. phaeocaulis, C. kwangsiensis and C. longa. The mixed standards contain 32 fatty acid methyl esters as described in the Chemicals section. Fatty acids were represented as the corresponding methyl esters. 1. C14:0; 2. C15:0; 3. C16:0; 4. C16:1 n-7; 5. C17:0; 6. C17:1 n-7; 7. C18:0; 8. C18:1 n-9; 9. C18:2 n-6; 10. C18:3 n-3; 11. C20:0; 12. C20:1 n-9; 13. C22:0; 14. C24:0.
