毛羽扇豆Lupinus hirsutus L.是一年生的含有羽扇豆生物碱的草本植物。作者曾经报道了从羽扇豆的地上部分得到9个生物碱,另外还报道了生长早期的秧苗中的生物碱成分,以及在发芽过程中生物碱结构变化情况。本文报道从秧苗中分离得到了一种新生物碱:N-氧化(-)多花羽扇豆碱〔(-)multiflorine N-oxide〕(1),另外还一并获得了包括(一)-多花羽扇豆碱〔(一)-multiflorine〕(2)等12个已知生物碱的研究工作,对(1)进行了结构鉴定。日光照射下于25℃将毛羽扇豆种子在潮湿的蛭石中生长7-10d而得到羽扇豆秧
Lupinus hirsutus L. is an annual herb containing lupine alkaloids. The authors have reported that nine alkaloids were obtained from the aerial parts of lupins. In addition, the alkaloids in the seedlings during early growth and the alkaloid structure during germination were reported. This paper reports that a new alkaloid was isolated from seedlings: N-oxidized (-) multiflorine N-oxide ((-)) (1), and was also obtained together with (a)-multiple The study of 12 known alkaloids, such as flowering lupine [(a)-multiflorine] (2), was carried out to identify the structure of (1). The Lupine seeds are grown in moist vermiculite at 25°C for 7-10 days under sunlight to give lupins
