Compound Extraction and Component Analysis on Volatile Oil of Artemisia Argyi
Abstract:
Abstract: In order to prepare natural anti-mosquito agent, the volatile oil was extracted from artemisia argyi by three-step of water extraction, steam distillation and organic solvent extraction. Three factors have been optimized. They were material/liquid ratio, distillation time and crushing particle size having influence on the extraction efficiency. The experimental results showed as: the optimum extraction process was that material/liquid ratio for 1:20, distillation time for 4 hours and crashing particle size for 40 meshes. At optimized extraction process condition, the extraction efficiency was 0.71%. Chemical constituents were determined by gas chromatography-mass spectrometry apparatus (GC-MS). They were mainly single terpenoids and its derivatives, including monocylic single terpenoids and 2-ring single terpenoids. Primary components were eucalyptol, camphor, camphene, borneol and so on. This provided good foundation for preparation of anti-mosquito and anti-insect agent.
