对陕西漆籽在不同处理下漆籽油的物化特征进行了分析,并对日本漆籽及江西引种漆籽嫁接苗与实生苗漆籽的漆籽油进行了化学成分的对比分析,结果表明:经过水洗和石油醚浸泡过的陕西漆籽核提取的漆籽油透明澄清,颜色浅,得率相应的由9.61%提高到14.87%,酸值分别为9.79和6.95,明显低于未经任何处理而直接提取漆籽油的样品,处理后提取的漆籽油的皂化价及过氧化值则比未处理提取的漆籽油低;陕西漆籽油的亚油酸的相对含量则高达72%,具有较高的应用价值。江西引种的漆籽皮核易于分离,漆籽油中亚油酸的相对含量为56.222%。
The physico-chemical characteristics of the paint seed of Shaanxi Province under different treatments were analyzed, and the chemical compositions of the paint seed oil of the Japanese paint and the seedlings of grafted seedlings and seedlings of the seedlings were introduced. The results showed that: After washing and petroleum ether soaked in Shaanxi Laowei nuclear extraction of paint clear and transparent, light color, the corresponding rate of 9.61% increased to 14.87%, the acid value was 9.79 and 6.95, significantly lower than without any treatment However, when the sample of the paint was directly extracted, the saponification value and peroxide value of the paint was lower than that of the untreated paint. The relative content of linoleic acid in Shaanxi paint was as high as 72% Has high application value. The seed coat core introduced from Jiangxi is easy to separate, the relative content of linoleic acid in paint oil is 56.222%.
