从太白米 N otholirion bulbuliferum干燥小鳞茎的正丁醇提取物中分离并鉴定了 3个甾体生物碱苷 ,经 IR、1 3CNMR、MS等方法分别鉴定为茄次碱 - 3- O- β- D-吡喃葡萄糖苷 (solanidine- 3- O- β- D- glucopyranoside, )、茄次碱 - 3- O-α- L -吡喃鼠李糖基 - (1→ 2 ) -β- D-吡喃葡萄糖苷 (solanidine- 3- O-α- L - rhamnopyranosyl-β- D -glucopyranoside, )、茄次碱 - 3- O- α- L-吡喃鼠李糖基 - (1→ 2 ) -〔β- D-吡喃葡萄糖基 - (1→ 4)〕- β- D-吡喃葡萄糖苷 (solanidine- 3- O- α- L- rhamnopyranosyl-〔β- D- glucopyranosyl- (1→ 4)〕- β- D- glucopyranoside, )。其中化合物 为首次从本植物中分得
Three steroidal alkaloid glycosides were isolated and identified from n-butanol extracts of dried bulblets of TaebaekN. otholirion bulbuliferum and identified as Solanets-3-O-β- by IR, 13C NMR and MS. D-glucopyranoside (solanidine-3-O-β-D-glucopyranoside), Solanitin-3-O-α-L-rhamnopyranosyl-(1→ 2 )-β-D- Glucopyranoside (solanidine-3-O-α-L-rhamnopyranosyl-β-D-glucopyranoside), solanesyn-3-O-α-L-rhamnopyranosyl-(1→ 2)- [β-D-glucopyranosyl-(1→4)]-β-D-glucopyranoside (solanidine- 3-O- α- L-rhamnopyranosyl-[β- D-glucopyranosyl- (1→ 4) ]- β-D-glucopyranoside, ). Among them, the compound was firstly obtained from the plant
