###我仔细阅读了您上传的这篇文献("Volatile compounds released by acid hydrolysis in jackfruit...")。
以下是该文献的主要结论、研究意义,以及关于芳樟醇 (linalool) 的具体情况总结:
Volatile compounds released by acid hydrolysis in jackfruit (Artocarpus
heterophyllus Lam.). A comparative study by using SDE and
HS-SPME techniques
文献主要结论
这篇研究的主要目的是利用酸水解 (acid hydrolysis) 来释放菠萝蜜 (jackfruit) 中与糖苷结合的“风味前体物质”(aroma precursors),并比较两种提取技术(SDE 和 HS-SPME)的效果 。
共鉴定出69种挥发物: 综合两种提取方法和两种pH条件,研究共鉴定出69种挥发性化合物,包括29种酯类、20种醛类、6种萜烯类、7种酮类和7种醇类 。
柠檬烯 (Limonene) 含量最高: 在所有检测到的化合物中,柠檬烯 (Limonene) 的浓度最高,在HS-SPME (pH 3) 条件下的检测值达到了 5.835 mg/kg 。
