title: [Homoisoflavanones and stilbenes from fresh bulb of Scilla scilloides].
abstract: Mian-Zao-Er was collected from the bulbs of Scilla scilloides (Lindl. ) Druce, belonging to the Hyacinthaceae family. 17 compounds were obtained using various column chromatographies on macroporus resin (HPD100), silica gel, Sephadex LH-20 and ODS, as well as semi-preparative HPLC. Their structures were elucidated on the basis of physicochemical properties and spectral data as 2-hydroxy-7-methoxyscillascillin (1), scillascillin (2), 5,7-dihydroxy-3',4'-dimethoxyspiro 2H-1-benzopyran-7'-bicyclo[4.2.0 ] octa [1,3,5 ] -trien } -4-one (3), socialinone (4), 4-methylresveratrol (5), (E)-resveratrol (6), scillavoneA (7), 3,9-di- hydroeucomnalin (8), 3-(3-hydroxy-4-methoxybenzyl) -5,7-dihydroxychroman-4-one (9), (3R)-5,7,3'-trihydroxy-4'-methoxyspiro (2H-1-benzopyran-7'-bicyclo[4, 2, 0] octa [1, 3, 5]-trien} -4-one (10), scillabene A (11), 2-hydroxyscillascillin (12), 3-(4-hydroxybenzyl) -5,7-dihydroxychroman-4-one (13), 3-( 4-hydroxybenzylidene) -5, 7-dihydroxychroman-4-one (14), 3-( 4-hydroxybenzyl) -5-hydroxy-7,8-dimethoxychroman-4-one (15), 3-(4-hydroxybenzyl) -5-hydroxy-6, 7-dimethoxychroman-4-one (16), and 3-(4-hydroxybenzyl)-5,8-hydroxy-7-methoxychroman-4-one (17). Among them, compounds 3, 4, 6, 9, 13 and 15-17 were isolated from this plant for the first time.
