摘要
对浙江、云南、四川、江苏、湖南、湖北、福建、河南、贵州9个地区的茶叶籽油活性成分进行比较分析。结果表明,茶叶籽油中总酚含量以四川、贵州和云南最为突出,在900 mg/kg以上,其他地区差异不显著（400~660 mg/kg）;VE含量以四川茶叶籽油最高,可达68.55 mg/100 g,而江苏茶叶籽油中生理活性最强的α-VE含量（31.94 mg/100 g）最多;角鲨烯、三萜类物质羽扇豆醇与4种甾醇类物质（菜油甾醇、豆甾醇、羊毛甾醇和谷甾醇）在所有地区茶叶籽油中均被检出;除湖南、湖北、福建外,其他几个地区茶叶籽油中都含有β-香树脂醇;此外,在所有地区的茶叶籽油中都检出1种类胡萝卜素——虾青素;四川和贵州的茶叶籽油中总甾醇含量最多,分别为5 710.4 mg/kg和5 539.3 mg/kg。综合分析,四川、贵州的茶叶籽油中活性成分含量最高,品质最好。
The active constituents in tea seed oils from Zhejiang, Jiangsu, Hubei, Hunan, Fujian, Henan, Yunnan, Sichuan and Guizhou were compared and analyzed. The results showed that the contents of total phenols in tea seed oils from Sichuan, Guizhou and Yunnan were the highest, above 900 mg/kg, while the total phenols in tea seed oils from other six areas had no obvious difference （400 -660 mg/kg） ; the content of VE in tea seed oil from Sichuan was the highest, reaching 68.55 mg/100 g, but the content of α - VE with the strongest biological activity in tea seed oil from Jiangsu was the highest, about 31.94 rag/100 g; squalene, triterpene like lupeol and four kinds of sterols substances （campesterol, stigmasterol, lanosterol and sitosterol ） were detected in tea seed oils from the nine areas, and β - amyrin was detected in tea seed oils from all the nine areas except Hunan, Hubei and Fujian; besides, astaxanthin, a kind of carotenoid, was detected in tea seed oils from the nine areas; the contents of total sterols in tea seed oils from Sichuan and Guizhou were the highest, about 5 710.4 mg/kg and 5 539.3 mg/kg respectively. The comprehensive analysis result indicated that the tea seed oils from Sichuan and Guizhou with the highest active constituents contents had the best quality.
