Abstract
Labdanes, leonurenones A-C, two known labdanes, luteolin 7-O-β-glucoside and luteolin were isolated and characterized from a commercial source of Leonotis leonurus. Genetic methods allowed for identification of the plant material. The leonurenones contain an uncommon α,β-unsaturated enone moiety in ring B, and leonurenones A and B were evaluated in a competitive inhibition assay at the GABA A neuroreceptor site.
摘要
从商业来源的 Leonotis leonurus 中分离并鉴定了 Labdanes、leonurenones A-C、两种已知的 Labdanes、木犀草素 7-O-β-葡萄糖苷和木犀草素。遗传方法允许鉴定植物材料。Leonurenones 在环 B 中含有不常见的α，β-不饱和烯酮部分，并且在 GABA A 神经受体部位的竞争性抑制测定中评估了 leonurenones A 和 B。
