Five glycosides, 2-(trans-cinnamoyloxy-methyl)-1-butene-4-O-beta-D-glucopyranoside (1), 4-(6'-O-trans-cinnamoyl)-(2-hydroxymethyl-4-hydroxy-butenyl-beta-D-glucopyranoside (2), 6''-O-trans-p-coumaroyl-(4-hydroxybenzoyl)-beta-D-glucopyranoside (3), 6'-O-(4-methoxy-trans-cinnamoyl) alpha/beta-D-glucopyranose (4) 6'-O-(4''-methoxy-trans-cinnamoyl)-kaempferol-3-beta-D-glucopyranoside (7) along with six known compounds, (+)-isolariciresinol 3a-O-beta-D-glucopyranoside (8) (+)-lyoniresinol 3a-O-beta-D-glucopyranoside (9), apigenin 7-O-beta-D-glucopyranoside (10), quercetin 3-O-beta-D-glucopyranoside (11), 6'-O-cinnamoyl-alpha/beta-D-glucopyranose (6) 6'-O-p-coumaroyl-alpha/beta-D-glucopyranose (5) were isolated from the whole plant of Spiraea canescens. Some of these compounds showed potent radical scavenging activity in relevant non-physiological assays. Their structures were determined by NMR spectroscopic and CID mass spectrometric techniques.
从灰毡毛忍冬全草中分离得到了 5 个糖苷类化合物，分别为 2-(反式肉桂酰氧基甲基)-1-丁烯-4-O-β-D-吡喃葡萄糖苷（1）、4-(6′-O-反式肉桂酰基)-(2-羟甲基-4-羟基丁烯基)-β-D-吡喃葡萄糖苷（2）、6′′-O-反式对香豆酰基-(4-羟基苯甲酰基)-β-D-吡喃葡萄糖苷（3）、6′-O-(4-甲氧基反式肉桂酰基)-α/β-D-吡喃葡萄糖苷（4）、6′-O-(4′′-甲氧基反式肉桂酰基)-山奈酚-3-β-D-吡喃葡萄糖苷（7），以及 6 个已知化合物，(+)-异落叶松脂醇 3a-O-β-D-吡喃葡萄糖苷（8）、(+)-丁香树脂醇 3a-O-β-D-吡喃葡萄糖苷（9）、芹菜素 7-O-β-D-吡喃葡萄糖苷（10）、槲皮素 3-O-β-D-吡喃葡萄糖苷（11）、6′-O-肉桂酰基-α/β-D-吡喃葡萄糖苷（6）、6′-O-对香豆酰基-α/β-D-吡喃葡萄糖苷（5）。这些化合物在相关的非生理测定中表现出强烈的自由基清除活性。它们的结构通过 NMR 光谱和 CID 质谱技术确定。
