The amorphane sesquiterpenes, deoxyarteannuin B and dihydro-deoxyarteannuin B, were isolated from Artemisia annua and their structures mainly determined by two-dimensional NMR spectoscopic analyses. The irregular monoterpene, trans-5-hydroxy-2-isopropenyl-5-methylhex-3-en-1-ol, was also characterized in the same way, and its structure was confirmed by synthesis from lavandulol. All of these natural
紫花烷倍半萜、脱氧青蒿素 B 和二氢脱氧青蒿素 B 是从青蒿中分离出来的,它们的结构主要通过二维核磁共振光谱分析确定。不规则单萜, trans-5-hydroxy-2-isopropenyl-5-methylhex-3-en-1-ol, 也以同样的方式表征, 其结构由薰衣草醇合成证实。建议所有这些天然产物都是通过自氧化反应形成的。还报告了通过相同方法确定的已知天然产物表脱氧青蒿素 B 和异环内酯的 1H 和 13C 共振的完整分配。
