張斌 許莉勇 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。 Extracting camphor wood oil from camphor tree seeds ZHANG Bin(Medicine School of Zhejiang
Province,Ningbo
315010,Zhejiang,China) 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). |
