摘　　要：A comparative study of Cannabis sativa(Hemp)essential constituents obtained by using Supercritical Fluid Extraction(SCFE),Steam Distillation(SD)and Hydrodistillation(HD)is presented here.The optimized extraction temperatures were 130,110and 50℃for hydrodistillation,steam distillation and supercritical fluid extraction respectively.The essential oil of C.sativa was analyzed by using Gas chromatography mass spectrometry(GC-MS).A total of 33,30and 31components have been identified in HD,SD and SCFE respectively.Yield of essential oil using SCFE(0.039%)was more than HD(0.025%)and SD(0.035%)extraction respectively.The main component of sesquiterpenes obtained by hydrodistillation at 130℃with their percentages included caryophyllene(40.58%),trans-α-bergamotene(5.41%),humulene(10.97%),cis-β-farnesene(8.53%)and monoterpenes includedα-pinene(2.13%),d-limonene(6.46%),p-cymol(0.65%)and cineole(2.58%)respectively.The main component of sesquiterpenes obtained by SD steam distillation at110℃including caryophyllene(38.60%)trans-α-bergamotene(4.22%),humulene(10.26%),cis-β-farnesene(6.67%)and monoterpenes includedα-pinene(3.21%),d-limonene(7.07%),p-cymol(2.59%)and cineole(3.88%)whereas the more percentages of major components were obtained by SCFE at 50℃included caryophyllene(44.31%),trans-α-bergamotene(6.79%),humulene(11.97%)cis-β-farnesene(9.71%)and monoterpenes includedα-pinene(0.45%),d-limonene(2.13%)p-cymol(0.19%)and cineole(1.38%)respectively.We found yield/efficiency,chemical composition,quality of the essential oils by supercritical fluid extraction superior in terms of modern,green,saving energy and a rapid approach as compared to traditional techniques.A comparative study of Cannabis sativa（Hemp）essential constituents obtained by using Supercritical Fluid Extraction（SCFE）,Steam Distillation（SD）and Hydrodistillation（HD）is presented here.The optimized extraction temperatures were 130,110 and 50 ℃for hydrodistillation,steam distillation and supercritical fluid extraction respectively.The essential oil of C.sativa was analyzed by using Gas chromatography mass spectrometry（GC-MS）.A total of 33,30 and 31components have been identified in HD,SD and SCFE respectively.Yield of essential oil using SCFE（0.039%）was more than HD（0.025%）and SD（0.035%）extraction respectively.The main component of sesquiterpenes obtained by hydrodistillation at 130 ℃ with their percentages included caryophyllene（40.58%）,trans-α-bergamotene（5.41%）,humulene（10.97%）,cis-β-farnesene（8.53%）and monoterpenes includedα-pinene（2.13%）,d-limonene（6.46%）,p-cymol（0.65%）and cineole（2.58%）respectively.The main component of sesquiterpenes obtained by SD steam distillation at110 ℃ including caryophyllene（38.60%）trans-α-bergamotene（4.22%）,humulene（10.26%）,cis-β-farnesene（6.67%）and monoterpenes includedα-pinene（3.21%）,d-limonene（7.07%）,p-cymol（2.59%）and cineole（3.88%）whereas the more percentages of major components were obtained by SCFE at 50℃included caryophyllene（44.31%）,trans-α-bergamotene（6.79%）,humulene（11.97%）cis-β-farnesene（9.71%）and monoterpenes includedα-pinene（0.45%）,d-limonene（2.13%）p-cymol（0.19%）and cineole（1.38 %）respectively.We found yield/efficiency,chemical composition,quality of the essential oils by supercritical fluid extraction superior in terms of modern,green,saving energy and a rapid approach as compared to traditional techniques.
