Abstract：
The natural product ambergris is only found rarely on beaches, as jetsam. Even more scarce, or even absent, are accounts of flotsam ambergris. Here, we report the chemical analysis of a rare, large piece (>100kg) of flotsam found in the Atlantic in 2019. About 95% of subsamples from the outside of the coprolith was soluble in dichloromethane. Of this, FTIR spectroscopy, APCI-MS and GC-MS indicated the presence of ambrein. Radiocarbon dating indicated that the sample was post 1950s in age. The 13C/12C isotope ratio (-22.5 ‰) was typical of those reported to date for whale \'body\' ambergris. Metals of ambergris have hardly been reported previously. The distribution found here for the flotsam, was dominated by copper and zinc, which is similar to that of several squid species. This is also consistent with the presence of squid beaks in the coprolith. Squid are a major prey species of sperm whales.
摘要：
仅在海滩上很少发现天然产物龙涎香，作为Jetsam.甚至更稀缺，甚至缺席，都是龙涎香的账户。这里,我们报告了一种罕见的化学分析，2019年在大西洋发现了大块(>100公斤)的漂浮物。约95%的亚样来自共前列腺外面，可溶于二氯甲烷。其中，FTIR光谱,APCI-MS和GC-MS表明存在血管肽。放射性碳测年表明该样本的年龄在1950年代后。13C/12C同位素比（-22.5‰）是迄今为止报道的鲸鱼“身体”龙胆的典型代表。龙涎香的金属以前几乎没有报道过。这里发现的漂浮物的分布，以铜和锌为主，类似于几种鱿鱼。这也与黑石中鱿鱼喙的存在是一致的。鱿鱼是抹香鲸的主要猎物。
