Two new jatropham derivatives and three new steroidal saponins were isolated from the fresh bulbs of Lilium hansonii, along with previously known compounds. The structures of the new compounds were elucidated, on the basis of spectroscopic data and chemical evidence, and by comparing them with those of known compounds, as (-)-5-hydroxy-3-methyl-3-pyrrolin-2-one (jatropham) 5-O-beta-D-glucopyranosy
从百合的新鲜鳞茎中分离出两种新的麻风树衍生物和三种新的甾体皂苷,以及以前已知的化合物。根据光谱数据和化学证据,并将它们与已知化合物的结构进行比较,阐明了新化合物的结构,如 (-)-5-hydroxy-3-methyl-3-pyrrolin-2-one ( jatropham) 5-O-β-D-吡喃葡萄糖基-(1----3)-β-D-吡喃葡萄糖苷,(2S*,4R*)-1-(3-methyl-2-oxo-3-pyrrolinyl) -4-methyl-5-oxo-2-pyrr olilidecarboxylic acid, 26-O-beta-D-glupyranosyl-(25R)-5 alpha-furostan-3 beta,22 zeta-diol 3-O-alpha-L-鼠李糖基-(1----2)-O-[β-D-吡喃葡萄糖基-(1----4)]-β-D-吡喃葡萄糖苷,(25R)-5 α-spirostan-3β,12
