GC-MS analysis of compounds in leaves and flowering stages (S1 and S4). (A) Chromatogram profiles of T. coccineum leaves and flowering stages (S1 and S4) for extracts analyzed by GC-MS at the ion current (EIC) for m/z 123 and 107. 1. cinerin I; 2. jasmolin I; 3. pyrethrin I; 4. unknown 1; 5. cinerin II; 6. jasmolin II; 7. pyrethrin II; 8. unknown 2. (B) GC-MS analysis of terpene in leaves and flowering stages (S1 and S4) at the ion current (EIC) for m/z 93. 1. Elixene; 2. unknown; 3. caryophyllene I; 4. β-copaene 1; 5. (E)-β-famesene; 6. γ-muurolene; 7. linalool; 8. α-bergamotene; 9. germacrene D; 10. α-farnesene; 11. α-patchoulene. (C) The relative content of pyrethrins. The value for L was set as 1 and used as the reference, except for jasmolin II, as its content was too low to measure in the L stages, so the value of S1 stages was set as a reference. (D) The relative content of terpenes. The value for L was set as 1 and used as the reference. Error bars represent the standard deviations of the mean values of three replicates, and significant differences (*: p < 0.05; **: p < 0.01) were tested using Student’s paired t-test.
