摘 要:应用反相硅胶ODS、大孔树脂、葡聚糖凝胶Sephadex LH-20和HPLC等多种色谱分离技术,从中药山慈菇来源之一——独蒜兰Pleione bulbocodioides干燥假鳞茎中分离得到10个丁二酸苄酯苷类化合物和1个苄醇糖苷类化合物,根据理化性质和波谱数据分别鉴定为loroglossin(1),grammatophylloside A(2),cronupapine(3),(-)-(2R,3S)-1-[4-(β-D-吡喃葡萄糖氧)苄基]-4-甲基-2-异丁基酒石酸酯(4),vandaterosideⅡ(5),grammatophylloside B(6),(-)-(S)-1,4-二-[4-(β-D-吡喃葡萄糖氧)苄基]-2-异丙基苹果酸酯(7),gymnosideⅠ(8),militarine(9),dactylorhin A(10),天麻苷(11)。其中化合物1~7为首次从独蒜兰属植物中分离得到。Ten glucosyloxybenzyl 2-isobutylmalates and one benzyl alcohol glycoside were isolated from the dry tuber of Pleione bul- bocodioides, which is a specie of Orchidaceae family and its dry tuber is one of the main sources of traditional Chinese medicine "shan- ci-gu", by a combination of various column chromatographic methods, including ODS, macroporous adsorbent resin, Sepheadex LH- 20, and preparative HPLC. Their structures were identified on the basis of chemical evidences and spectroscopic analysis asloroglossin ( 1 ), grammatophylloside A ( 2 ), cronupapine ( 3 ), ( - ) -( 2R, 3S) -1- (4-β-D-glucopyranosyloxybenzyl) -4-methyl-2-isobutyhartrate (4), vandateroside Ⅱ (5), grammatophylloside B ( 6 ), bis [ 4- (β-D-glucopyranosyloxy) -benzyl ] ( S ) -2-isopropylmalate ( 7 ), gym- noside I (S), militarine (9), dactylorhin A (10), gastrodin (11). Compounds 1-7 were isolated from this genus for the fir - - st time.
