张斌 许莉勇 摘 要: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%~3.10%,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。 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). |
