Abstract

Green leaves of leek and chive mainly contain kaempferol glycosides, with mono- and di-glycosides dominating in leek and di- and tri-glycosides in chive. In leek glucose is dominant as sugar component compared to xylose; in chive we found glucose and galactose. Kaempferol-3-beta-D-glucoside and kaempferol-3-xylosyl-beta-D-glucoside were isolated from leek and the 3-beta-D-glucosides of kaempferol, quercetin and isorhamnetin as by-glycosides from chive. In leek traces of quercetin-3-glucoside were identified by tlc, but no spiraeoside (quercetin-4'-glucoside) could be detected in the two species. The bulbs of garlic and leek contain only few milligram of glycosides of kaempferol and quercetin per kg fresh weight.

摘要

韭菜和细香葱的绿叶主要含有山奈酚糖苷,韭菜中以单糖苷和二糖苷为主,细香葱中以二糖苷和三糖苷为主。与木糖相比,韭菜中葡萄糖作为糖成分占主导地位;在细香葱中,我们发现了葡萄糖和半乳糖。从韭菜中分离出山奈酚-3-β-D-葡萄糖苷和山奈酚-3-木糖基-β-D-葡萄糖苷,从细香葱中分离出山奈酚、槲皮素和异鼠李素的3-β-D-葡萄糖苷作为次要糖苷。通过薄层色谱法在韭菜中鉴定出痕量的槲皮素-3-葡萄糖苷,但在这两个物种中均未检测到绣线菊苷(槲皮素-4'-葡萄糖苷)。大蒜和韭菜的鳞茎每千克鲜重仅含有几毫克的山奈酚和槲皮素糖苷。
