樟树籽提取樟油的试验

Extracting camphor wood oil from camphor tree seeds

以樟树青籽和樟树紫籽为研究对象 ,采用浸提法与水蒸汽蒸馏法来提取樟油。结果表明 ,用丙酮、石油醚和乙醇作溶剂浸提樟树籽 ,青籽的得油率为 2 70 %～ 3 1 0 % ,紫籽的得油率为 0 70 %～ 0 93% ;用水蒸气蒸馏樟树籽 ,青籽的得油率为 2 80 % ,紫籽的得油率为0 90 %。樟树青籽提取樟油效果优于樟树紫籽。表 3参 4。

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).
