Volatile constituents of Aristolochia trilobata L. (Aristolochiaceae): a rich source of sulcatyl acetate

摘要

Analysis of the volatile fraction of Aristolochia trilobata stem led to the identification of 6-methyl-5-hepten-2-yl acetate (23.31 ?± 0.28%), limonene (15.43 ?± 0.030%), linalool (8.70 ?± 0.29%), p-cymene (7.81 ?± 0.12%), bicyclogermacrene (4.21 ?± 0.11%), and spathulenol (4.17 ?± 0.14%) as the major constituents of the essential oil. Linalool (29.51 ?± 0.49%), 6-methyl-5-hepten-2-ol (19.54 ?± 0.82%), 6-methyl-5-hepten-2-yl acetate (8.92 ?± 0.16%), and a-terpineol (4.62 ?± 0.05%) were identified as major constituents of the hydrolate. The compound 6-methyl-5-hepten-2-yl acetate was isolated for the first time from this plant and was identified as the major component of the volatile fraction.
