从豆科野决明属植物牧马豆ThermopsislanceolataR.Br.的全草中分得6个生物碱。经物理常数测定及光谱分析,分别鉴定为黄华碱(Ⅰ),13-羟基黄华碱(Ⅱ),金雀花碱(Ⅲ),N-甲基金雀花碱(Ⅳ),5,6-dehydrolupanine(Ⅴ)和N-(3-氧代丁基)金雀花碱(Ⅵ)。其中化合物Ⅱ和Ⅴ为首次从该植物中分得,化合物Ⅵ为首次从本属植物中分得。

[Abstract]
Six quinolizidine-type alkaloids were isolated from the whole plant of Thermopsis lanceolata R. Br,They were thermopsine(I),13β-hydroxylthermopsine(Ⅱ),cytisine(Ⅲ),N-methylcytisine(Ⅳ),5,6-dehydrolupanine(V)and N-(3-oxobutyl) cytisine(VI)respectively. Compound B and V were obtained from, this species for the first time while compound A was isolated for the first time from genus Thermopsis. All structures were elucidated on the basis of physico-chemical contants and spectroscopic evidences.
