摘　　要：从龙胆科滇黄芩属植物滇黄芩(Veratrilla baillonii Franch.)中分离得到两个新的(口山)酮甙,分别命名为:滇黄芩甙C(I)和滇黄芩甙D(Ⅱ).经各种光谱解析及化学反应证明,其结构推定为:2,3,4,5-四甲氧(口山)酮-1-O-β-D-吡喃葡萄糖基(6←l)-β-D-吡喃木糖甙(I)和3,4,5-三甲氧基(口山)酮-1-O-β-D-吡喃葡萄糖基(6←1)-β-D-吡喃本糖甙(Ⅱ).Two new xanthone glycosides,Veratriloside C(Ⅰ)and Veratriloside D(Ⅱ)were isolated from Veratrilla baillonii Franch. on the bases of spectroscopy and chemical reaction. Their structure were deduced as 2, 3, 4, 5-tetramethoxy-xanthone-1-O-β-D-glucopyranosyl (6←1)-β-D-xylopyranoside (Ⅰ)and 3,4,5-trimethoxy-xanthone-1-O-β-D-glucopyranosyl(6←1)-β-D-xylopyranoside(Ⅱ).
