There are several kinds of chemical and (biological) synthesis methods for preparation of farnesol, besides direct separation from natural material.

金合欢醇存在于某些植物的花、叶子和种子的精油中,可应用于调香、抗菌、杀虫和制药等领域。

The yield of farnesol in the isomerized mixture from nerolidol is 37.

研究结果表明,3类催化剂中催化效果较好的分别是偏钒酸铵、 原钒酸丁酯和原钒酸三苯基硅酯,它们作为单一催化剂均可使橙花叔醇发生较好的异构化反 应,金合欢醇的产率分别为37。

It showed that main constituents are linalool, geraniol, farnesol, safrole, citral, t-anethole , decanal and lauric aldehyde respectively and with high cont.

从它们的利用部位花、果、叶和根中,可提取芳香油,主要成分分别为芳樟醇、香叶醇、金合欢醇、黄樟素、柠檬醛、茴香醚及癸醛、十二碳醛等,含量相当高,为重要调香原料,有的作药用,颇具发展种植和开发利用价值。
