| Abstract: | Volatile oil was extracted from leaves of Vitex negundo L.var.heterophyl(Franch.)Rehd by steam distillation(SD).The extraction yield of volatile oil by SD was 1.2%.First,the volatile oil was rec- tified.Then the target fraction was further purified by silica gel column chromatography and silica gel im- pregnated with silver nitrate column chromatography.Finally,β-caryophyllene was analyzed with infrared spectroscopy,gas chromatography-mass spectroscopy(relative peak areas was 98.2%),and nuclear mag- netic resonance spectroscopy. |
