GC-MS Analysis of Pyrethrum Seed and Leaf Oil Constituents.

Chloroform extracts of complete seeds, including trichomes (A), seed contents after trichome extraction (B), contents of seed glandular trichomes only (C), complete young leaves including trichomes (D), leaf contents after trichome extraction (E), and contents of young leaf glandular trichomes (F). The major pyrethrin components identified by mass spectrometry are labeled by numbers: 1, cinerin I; 2, jasmolin I; 3, PI; 4, cinerin II; 5, jasmolin II; 6, pyrethrin II; and the major STLs by letters A to M (see Supplemental Table 1 online for GCMS identification details).
