A total of 38 volatile components were identified in Rhodobryum giganteum (Schwaegr.) Par. collected from two different geographic regions by headspace solid-phase microextraction (HS-SPME), combined with gas chromatography/mass spectrometry (GC/MS). The volatile components included some aliphatic and aromatic aldehydes, monoterpene hydrocarbons and a sesquiterpene (alpha-farnesene), with 1-met...

As a quarantine pest of conifer, Sirex noctilio has caused widespread harm around the world. It is expected that molecular mechanism protein–ligand binding can be elucidated to carry out control. Through studies SnocOBP12–ligand hydrophobic and dynamics responsible amino acid residues identification, we got some promising results. SnocOBP12 had general excellent affinity for host plant volatile...

The oil obtained by hydrodistillation of aerial parts of Phlomis elliptica Benth. (Labiatae), which is a rare shrub endemic to Iran, was subjected to GC-FID and GC-MS analyses. Thirty-one constituents, making up about 98.4 % of the total composition of oil, were characterized. Monoterpenes, sesquiterpenes and other compounds constituted 13.4 %, 78.9 % and 6.1 % of the essential oil, respectivel...
