摘　　要：从云南烤烟型烟叶中分得7个糖苷类化合物,通过理化常数测定和光谱分析其化学结构分别鉴定为东莨菪甙(Scopolin,1)、槲皮素-3-β-D-芸香糖甙(Rutin,2)、山柰酚-3-O-新橙皮糖苷(Kaempferol-3-O-neohesperido-side,3)、3-氧代-α-紫罗兰醇-β-D-吡喃葡萄糖甙(3-oxo-α-ionol-β-D-glucopyranoside,4)、7,8-二氢-3-氧代-α-紫罗兰醇-β-D-吡喃葡萄糖甙(7,8-dihydro-3-oxo-α-ionol-β-D-glucopyranoside,5)、异秦皮定-6-O-β-D-吡喃葡萄糖甙(Iso-fraxetin-6-O-β-D-glucopyranoside,6)、异香豆素萄糖甙(Delphoside,7)。化合物3、5、6和7为首次从烟叶中分离得到。Seven glycosidic components were isolated from flue-cured tobacco （Nicotiana tabacum L. ） leaves grown in Yuxi,Yunnan Province. Their chemical structures were determined by physical and chemical constants and the data of spectroscopic identifications. They are Scopolin （ 1 ）, Rutin （ 2 ）, Kaempferol-3-O-neohesperidoside （ 3 ）, 3-oxo-α-ionol-β- D-glucopyranoside （4）, 7,8-dihydro-3-oxo-α-ionol-β-D-glucopyranoside （ 5 ）, Isofraxetin-6-O-β-D-glucopyranoside （ 6 ） and Delphoside（7）. Compounds 3,5,6 and 7 were isolated from Nicotinana species for the first time.
