两种以前未描述的巨替加曼葡萄糖苷，（3S）-3-羟基-4-氧代-7，8-二氢-β-紫罗兰酮-3-O-β-d-吡喃葡萄糖苷（1），（3S）-3-羟基-4-氧代-β-紫罗兰酮-3-O-β-d-吡喃葡萄糖苷（2），一种名为木贼苷A的脱胡萝卜素类葡萄糖苷（3）和一种名为木贼苷B的具有葡萄糖融合骨架的罕见芳香族化合物（4），从木贼地上部分分离得到35个已知化合物（5-39）。化合物的结构经1D和2D NMR、IR、CD和HR-MS等波谱方法确证。
Two previously undescribed megastigmane glucosides, (3S)-3-hydroxy-4-oxo-7,8-dihydro-β-ionone-3-O-β-d-glucopyranoside (1), (3S)-3-hydroxy-4-oxo-β-ionone-3-O-β-d-glucopyranoside (2), an apocarotenoid glucoside named equiseoside A (3) and an unusual aromatic compound with a glucose-fused skeleton named equiseoside B (4), together with 35 known compounds (5–39) were isolated from the aerial parts ofEquisetum sylvaticum. The structures of these compounds were elucidated by spectroscopic methods, including 1D and 2D NMR, IR, CD, and HR–MS.Graphical abstract
