Two new flavonoid glycosides, quercetin-3--(4--crotonyl)--D-glucopyranoside (1) and quercetin-3--[6--(2)-pentenoyl]--D-glucopyranoside (2), along with nine known ones, isoquercetin (3), astragalin (4), quercetin-3--(6--acetyl)--D-glucopyranoside (5), kaempferol-3--(6--acetyl)--D-glucopyranoside (6), quercetin-3--(6--crotonyl)--D-glucopyranoside (7), kaempferol-3--(6--crotonyl)--D-glucopyranoside (8), vitexin (9), isovitexin (10), and isorhamnetin-3---D-glucopyranoside (11), were isolated from the leaves of Moringa oleifera by various chromatographic technologies. Their structures were elucidated by spectroscopic methods including UV, IR, MS, and NMR. In addition, compounds 7 and 8 were isolated from this plant for the first time.
通过各种色谱技术从辣木叶中分离出两种新的黄酮苷，槲皮素 - 3 - - (4 - - 巴豆酰基) - - D - 吡喃葡萄糖苷（1）和槲皮素 - 3 - - [6 - - (2) - 戊烯酰基] - - D - 吡喃葡萄糖苷（2），以及九种已知的化合物，异槲皮苷（3）、紫云英苷（4）、槲皮素 - 3 - - (6 - - 乙酰基) - - D - 吡喃葡萄糖苷（5）、山柰酚 - 3 - - (6 - - 乙酰基) - - D - 吡喃葡萄糖苷（6）、槲皮素 - 3 - - (6 - - 巴豆酰基) - - D - 吡喃葡萄糖苷（7）、山柰酚 - 3 - - (6 - - 巴豆酰基) - - D - 吡喃葡萄糖苷（8）、牡荆素（9）、异牡荆素（10）和异鼠李素 - 3 - - D - 吡喃葡萄糖苷（11）。通过紫外光谱、红外光谱、质谱和核磁共振等光谱方法对它们的结构进行了鉴定。此外，化合物7和8首次从该植物中分离得到。
