Abstract A glycosidic fraction obtained from aerial parts of Diplolophium buchananii ssp. swynnertonii afforded 12 glucosides, of which three, or possibly four, are new. Thus, the main constituent is the new monoterpene, (1S,2R,4R,5S)- bornan-2,4,5-triol 2-O-β- d -glucopyranoside , the absolute configuration of which was determined by use of the exciton chirality rule. The chromone, (3S)-3,4- dihydro-5-methoxy
摘要 从 Diplolophium buchananii ssp 地上部分获得的糖苷级分。swynnertonii 提供了 12 种糖苷,其中 3 种,也可能是 4 种是新的。因此,主要成分是新的单萜,(1S,2R,4R,5S)-bornan-2,4,5-triol 2-O-β-d-glucopyranoside,其绝对构型是通过使用激子手性规则。色酮、(3S)-3,4-二氢-5-甲氧基-3-β-d-吡喃葡萄糖氧基-2,2,8-三甲基-2H、10H-苯并[1,2-b:3,4-b ']dipyran-10-one 或 (2' S )-2'-hydroxy-7-O-methylallopeucenin 2'-O-β-d-glupyranoside 是新的。香豆素也是如此,(2 R )-2'-hydroxymarmesin 2'-O-β-d-吡喃葡萄糖苷,在 C-1' 具有未知构型。(2' R )-7-Hydroxy-8-(2
