An investigation of the extracts from Allium neapolitanum has led to the isolation of 13 flavonoid glycosides, based on kaempferol, quercetin and isorhamnetin. Four of them are new compounds and have been identified as: kaempferol 3-O-[[2-O-alpha-L-rhamnopyranosyl-4-O-beta-D-glucopyranosyl]-beta-D- glucopyranoside]], isorhamnetin 3-O-[[2-O-alpha-L-rhamnopyranosyl-6-O-beta- D-glucopyranosyl]-beta-D-glucopyranoside], isorhamnetin 3-O-[[2-O-alpha-L-rhamnopyranosyl-6-O-beta-D-glycopyranosyl] beta-D-glucopyranoside]-7-O-beta-D-glucopyranoside and isorhamnetin 3-O-[[2-O-alpha-L-rhamnopyranosyl-6-O-beta-D-gentiobiosyl]- beta-D-glucopyranoside]]. The isolated compounds were evaluated for their anti-aggregation human platelet activity.
对那不勒斯葱提取物的研究已导致基于山奈酚、槲皮素和异鼠李素分离出13种黄酮苷。其中四种是新化合物，已被鉴定为：山奈酚3 - O - [[2 - O - α - L - 鼠李吡喃糖基 - 4 - O - β - D - 葡萄糖吡喃糖基] - β - D - 葡萄糖苷]、异鼠李素3 - O - [[2 - O - α - L - 鼠李吡喃糖基 - 6 - O - β - D - 葡萄糖吡喃糖基] - β - D - 葡萄糖苷]、异鼠李素3 - O - [[2 - O - α - L - 鼠李吡喃糖基 - 6 - O - β - D - 吡喃葡萄糖基]β - D - 葡萄糖苷] - 7 - O - β - D - 葡萄糖苷和异鼠李素3 - O - [[2 - O - α - L - 鼠李吡喃糖基 - 6 - O - β - D - 龙胆二糖基] - β - D - 葡萄糖苷]。对分离出的化合物进行了抗人血小板聚集活性评估。
