Abstract

An essential oil from the brown alga Sargassum thunbergii, prepared by a simultaneous distillation extraction method, contained in two types of volatile polyenes with a terminal double bond such as (6Z,9Z,12Z,15Z,18Z)-1,6,9,12,15,18-henicosahexaene and (6Z,9Z,12Z,15Z)-1,6,9,12,15-henicosapentaene and with their saturated terminal structures such as (3Z,6Z,9Z,12Z,15Z,18Z)-3,6,9,12,15,18-henicosahexaene and (3Z,6Z,9Z,12Z,15Z)-3,6,9,12,15-henicosapentaene. These volatile polyenes were identified by comparison with the GC-MS and NMR spectra of synthetics. The polyenes with the saturated terminal structures were found in the brown algae for the first time.

摘要

通过同时蒸馏萃取法制备的来自褐藻鼠尾藻的精油，含有两种带有末端双键的挥发性多烯，如(6Z,9Z,12Z,15Z,18Z)-1,6,9,12,15,18-二十一碳六烯和(6Z,9Z,12Z,15Z)-1,6,9,12,15-二十一碳五烯，以及它们具有饱和末端结构的异构体，如(3Z,6Z,9Z,12Z,15Z,18Z)-3,6,9,12,15,18-二十一碳六烯和(3Z,6Z,9Z,12Z,15Z)-3,6,9,12,15-二十一碳五烯。通过与合成物的气相色谱-质谱联用仪（GC-MS）和核磁共振（NMR）光谱进行比较鉴定出了这些挥发性多烯。具有饱和末端结构的多烯首次在褐藻中被发现。
