不同抽提试剂对油茶籽含油率测定的影响

Effect of Different Extracting Reagents on Determining Oil Content of Camellia oleifera Seeds

摘要:

摘要：为了利用抽提试剂优化测定油茶籽的含油率，本文选用石油醚（沸点30～60 ℃）、正己烷、丙酮、氯仿、乙醇等5种试剂分别对油茶籽进行抽提试验。结果表明：除乙醇外，石油醚、正己烷、丙酮、氯仿均可作为测定油茶籽含油率的抽提试剂；正己烷、丙酮、氯仿、乙醇的回收率高于石油醚，均为90%左右；正己烷、氯仿的抽提时间最短，为6 h，但正己烷的价格高于氯仿；综合考虑，氯仿的抽提效果最好。

Abstract:

Abstracts:In order to optimize determining oil content of Camellia oleifera seeds by extractive reagents, we chose five reagents including petroleum ether (boiling point 30～60℃), n–hexane, acetone, chloroform and ethanol for extractive test of Camellia oleifera seeds respectively. The results showed that four extractive reagents could extract Camellia oleifera seeds except for ethanol. The recovery rate of n hexane, acetone, chloroform and ethanol was about 90 percentage and higher than petroleum ether. The extracting time of n hexane and chloroform was the shortest, which was about 6 hours. The price of n hexane was higher than that of ethanol. All in all, chloroform was better than other four reagents.
