Abstract From the dried fruits of Alangium lamarckii, a novel tetrahydroisoquinoline-monoterpene glucoside, 3-O-demethyl-2-O-methylalangiside, was isolated along with alangiside. Re-examination of the constituents of the roots of Cephaelis ipecacuanha led to the isolation and identification of this same compound, as well as alangiside and that of another new glucoside, 7-O-methylipecoside. The structures
摘要 从海棠果干果中分离得到一种新型四氢异喹啉-单萜葡萄糖苷3-O-demethyl-2-O-methylalangiside。对 Cephaelis ipecacuanha 根成分的重新检查导致分离和鉴定了相同的化合物,以及阿兰糖苷和另一种新的葡萄糖苷 7-O-甲基岩脂苷。这两种新糖苷的结构是通过光谱和化学方法确定的。
