四、结果与讨论

一,本实验对分蘖葱头非挥发性成分进行了提取,分离和鉴定,从氯仿,乙酸乙酯和正丁醇部分共分离出11个单体化合物,经理化常数测定及光谱解析,鉴定出其中9个单体的结构,分别为:化合物ⅠN-[2-(4-羟基苯基)乙基]-3-(4-羟基苯基)-2-丙烯酰胺{N-[2-(4-hydroxylphenyl)ethyl]-3-(4-hydroxylphenyl)-2-propenamide},Ⅱ1,6-己内酰胺(1,6-caprolactam),Ⅲ胡萝卜苷(daucosterol),Ⅳβ-谷甾醇(β-sitosterol),Ⅴ槲皮素(quercetin),Ⅵ山柰酚(kaempferol),Ⅶ槲皮素4ˊ-0-β-D-吡喃葡萄糖苷(quercetin4ˊ-0-β-D-glucopyranoside),Ⅷ槲皮素3,4ˊ-二-0-β-D-吡喃葡萄糖苷(quercetin3,4ˊ-di-0--β-D-glucopyranoside),Ⅸ槲皮素3ˊ-甲氧基-4ˊ-0-β-D-吡喃葡萄糖苷(quercetin3ˊ-methoxy-4ˊ-0-β-D-glucopyranoside).化合物Ⅰ为国内外未见报道的新化合物,命名为分蘖葱头甲素(AlliumA),化合物Ⅱ为新天然产物,命名为分蘖葱头乙素(AlliumB),化合物Ⅲ-Ⅳ为首次从分蘖葱头中分离得到,Ⅴ-Ⅸ为本教研室已报道的黄酮类化合物.另外尚有两个化合物正在鉴定中.这一研究成果为更好地开发和利用东北特产分蘖葱头这一植物资源提供了科学依据.

二,对分蘖葱头提取物A,B进行了减肥作用的实验研究.结果表明,分蘖葱头提取物B能够显着降低营养性肥胖大鼠的脂肪,并且能够降低其全血低切粘度,中切粘度,起到减肥的作用.为开发新型,高效,安全的药物提供了一定的科学依据.
