摘　要：以樟樹青籽和樟樹紫籽為研究對象，采用浸提法與水蒸汽蒸餾法來提取樟油。結(jié)果表明，用丙酮、石油醚和乙醇作溶劑浸提樟樹籽，青籽的得油率為2.70%～3.10%，紫籽的得油率為0.70%～0.93%；用水蒸氣蒸餾樟樹籽，青籽的得油率為2.80%，紫籽的得油率為0.90%。樟樹青籽提取樟油效果優(yōu)于樟樹紫籽。表3參4。

Abstract：Camphor tree seeds including green seeds and mature seeds were collected in Ningbo City of Zhejiang Province．Extraction and distillation were used．The results showed that taking acetone，petroleum ether and ethanol as solvents in extraction，camphor wood oil percent of green seeds was 2.70%－3.10%，and percent of mature seeds．0.70%－0.93%；using of stem distillation，camphor wood oil percent of green seeds was 2.80%，and percent of mature seeds 0.90%．It is better to extract camphor wood oil from green seeds of camphor tree than from mature seeds （purple baccae）．
Keywords：Cimnamornum camphora；camphor tree seeds；camphor wood oil；extraction；distillation
