西南文殊兰(Crinum latifalium L.)化学成分研究

目的研究西南文殊兰的化学成分。方法采用多种层析方法分离西南文殊兰乙醇提取物的化学成分,通过其化合物理化性质及各种波谱数据鉴定化合物结构。结果共分离鉴定了15个化合物,它们的结构鉴定为：-sitosterol（1）,daucosterol（2）,5-methyl-2,4（1H,3H）-pyrimidinedione（3）,-purine（4）,p-hydroxybenzonic acid（5）,ethyl 4-hydroxybenzoate（6）,cinnamyl D-glucopyranoside（7）,benzyl-D-glucopyranoside（8）,adenosine（9）,uridine（10）,Z-cinnamic acid（11）,5-O-nitrosouridine（12）,3-methyl-1H-pyrimidine-2,4-dione（13）,N-methyl-benzamide（14）,E-cinnamic acid（15）。结论化合物3~4、7~10、12~14为首次从西南文殊兰中分离得到。

Study on the chemical constituents of Crinum latifalium

Objective To investigate the chemical constituents of Crinum latifalium.Methods The chemical constituents of methanol extract of C.latifalium were seperated by various chromatography Methods.The structures of these chemical constituents were identified by spectral data and physicochemical property.Results 15 compounds were respectively identified as:-sitosterol(1),daucosterol(2),5-Methyl-2,4(1H,3H)-pyrimidinedione(3),-purine(4),p-hydroxybenzonic acid(5),ethyl 4-hydroxybenzoate(6),cinnamyl D-glucopyranoside(7),benzyl-D-glucopyranoside(8),adenosine(9),uridine(10),Z-cinnamic acid(11),5-O-nitrosouridine(12),3-methyl-1H-pyrimidine-2,4-dione(13),N-methyl-benzamide(14),E-cinnamic acid(15).Conclusion Compounds 3-4,7-10,12-14 were isolated from C.latifalium for the first time.
