In this work, twenty-five water-soluble constituents were isolated from the bulbs of Lilium davidii var. unicolor, including two new compounds termed liliumtides A and B (1–2), and seventeen known compounds (3–4, 6–13, 15, 17, 21–25) isolated from the genus of Lilium for the first time. Their structures were established using high-resolution electrospray ionization mass spectroscopy and 1D and 2D nuclear
在这项工作中,从百合的鳞茎中分离出 25 种水溶性成分。单色,包括两种新化合物,称为百合花 A 和 B ( 1 – 2 ),以及从百合属中分离出的17 种已知化合物 ( 3 – 4 , 6 – 13 , 15 , 17 , 21 – 25 )首次。它们的结构是使用高分辨率电喷雾电离质谱和一维和二维核磁共振数据建立的。为进一步确认百合肽A的绝对构型,积累足够的样品研究其抗失眠作用,通过四步完成了百合肽A的全合成。戊巴比妥诱导睡眠时间试验表明,与空白对照组相比,百合肽A降低了睡眠潜伏期,显着增加了睡眠时间。这些结果表明,百合肽 A 可以作为一种天然的抗失眠先导化合物在制药和食品工业中进行研究。
