摘要:
研究白花丹Plumbago zeylanica L. 地上部分的化学成分。应用各种色谱方法分离; 用波谱学方法特别是二维核磁共振波谱的方法确定结构。从白花丹地上部分分离鉴定了7个化合物, 分别是: 1β,3β,11α-trihydroxy-urs-12-ene (1), androsta-1,4-diene-3,17-dione (2), 异信浓柿醇酮 (3), neoechinulin A (4), harman (5), ergostadiene-3β,5α,6β-triol (6), N-(N-benzoyl-S-phenylalaninyl)-S-phenylalaninol (7)。化合物1 为新化合物, 化合物2, 4–7 均为首次从该属植物中分离得到。
