洋金花的化学成分（英文）

目的：研究洋金花（Datura metel L.）的化学成分。方法：采用 50%乙醇提取, 利用硅胶、Sephadex LH-20、ODS 柱层析和 HPLC 等方法进行分离和纯化, 依据核磁数据分析进行结构鉴定。结果：分离得到 9 个化合物, 分别鉴定为（＋）松脂酚-O-β-D-双葡萄吡喃糖苷（1）, （＋）松脂酚-O-β-D-葡萄吡喃糖苷（2）, 对羟基苯乙醇（3）, N-p-香豆酰酪胺（4）, 顺式-N-p-香豆酰酪胺（5）, N-对羟基苯乙基-对羟基苯甲酰胺（6）, 苯乙醇-O-β-D-葡萄吡喃糖基（2→1）-O-β-D-葡萄吡喃糖苷（7）, 3-O-[β-D-葡萄吡喃糖基（1→2）]-β-D-半乳糖基-7-O-α-L-鼠李吡喃糖基-山柰酚（8）, 3-O-[β-D-葡萄吡喃糖基（1→2）]-β-D-葡萄吡喃糖基-7-O-β-D-葡萄吡喃糖基-山柰酚（9）。结论：化合物 1～9 均为首次从该植物中分离得到。

Chemical Constituents from the Flower of Datura metel

AIM： To study the chemical constituents of Datura metel L. METHODS： Extracted with 50% EtOH, the constituents were isolated and purified by silica gel, ODS and Sephadex LH-20 column chromatography as well as HPLC. Their chemical structures were elucidated on the basis of spectral data. RESULTS： Nine compounds were isolated and identified as （＋）-pinoresinol-O-β-D-diglucopyranoside （1）, （＋）-pinoresinol-O-β-D-glucopyranoside （2）, p-tyrosol （3）, trans-N-p-coumaroyltyramine （4）, cis-N-p-coumaroyltyramine （5）, 4-hydroxy-N-（4-hydroxyphenethyl） benzamide （6）, phenethyl alcohol-O-β-D-glucopyranosyl-（2→1）-O-β-D-glucopyranoside （7）, kaempferol-3-O-β-D-glucopyranosyl-（1→2）-β-D-galactopyranosyl-7-O-α-L-rhamnopyranoside （8）, and kaempferol-3-O-β-D-glucopyranosyl-（1→2）- β-D-galactopyranosyl-7-O-β-D-glucopyranoside （9）. CONCLUSION： Compounds 1-9 have been isolated from this plant for the first time. [
