Abstract From the aerial part of Teucrium flavum subsp. glaucum a new neo-clerodane diterpenoid, teuflavin, and a new 19-nor-neo-clerodane glucoside, teuflavoside, have been isolated, besides the previously known diterpene teuflin. The structures of teuflavin (19-acetoxy-4α,18:15,16-diepoxy-6β-hydroxy-3-keto-neo-cleroda-13(16),14-diene-20,ξ,12 S -hemiacetal) and teuflavoside (18-acetoxy-15,16-epox
摘要来自 Teucrium flavum subsp. 的地上部分。除了先前已知的二萜 teuflin 之外,glaucum 还分离了一种新的新克罗丹二萜类化合物 teuflavin 和一种新的 19-nor-neo-neo-clerodane 葡萄糖苷 teuflavoside。teuflavin (19-acetoxy-4α,18:15,16-diepoxy-6β-hydroxy-3-keto-neo-cleroda-13(16),14-diene-20,ξ,12 S-hemiacetal)的结构和teuflavoside (18-acetoxy-15,16-epoxy-19-nor-neo-cleroda-4,13(16),14-trien-20,12 S-olid-6β-yl-2'-O-acetyl-β - d -吡喃葡萄糖苷)是通过化学和光谱方法并通过与已知化合物的相关性建立的。
