Monoterpenes and sesquiterpenes produced by Artemisia annua plant. Fresh samples of stem, root, inflorescence, young leaf, and mature leaf were extracted with N-pentane containing 2 ng/μl nonyl acetate in a shaker at 28°C for 1 h and analyzed by gas chromatography–mass spectrometry (GC–MS). Peaks are: IS: Internal Standard, nonyl acetate; peaks 1–23 are monoterpenes: (1) santolina triene; (2) tricyclene; (3) α-thujene; (4) artemisia triene; (5) α-pinene; (6) camphene; (7) sabinene; (8) β-pinene; (9) β-myrcene; (10) I-phellandrene; (11) α-terpinene; (12) limonene; (13) 1,8-cineole; (14) γ-terpinene; (15) artemisia ketone; (16) trans-sabinene hydrate; (17) artemisia alcohol; (18) chrysanthenone; (19) camphor; (20) borneol; (21) 4-terpineol; (22) α-terpineol; (23) trans-carveol; peaks A–H are sesquiterpenes: (A) α-copaene; (B) β-cubebene; (C) β-elemene; (D) trans-caryophyllene; (E) trans-β-farnesene; (F) γ-curcumene; (G) naphthalene; (H) germacrene D; (I) β-selinene; (J) bicyclogermacrene; peaks labeled with dots represent monoterpenes and sesquiterpenes that were not unambiguously identified.
