Further chemical investigation of the whole plants of Gentiana loureirii led to the isolation and characterization of three new compounds, cyclic 4-O-β-D-glucopyranosylcaffeic acid dimer (1), a new α-tetralone, 4-hydroxy-6-methyl-α-tetralone 4-O-β-D-glucopyranoside (2), and 3β,30-dihydroxy-12-ursen-28-oic acid 28-O-β-D-glucopyranosyl ester (3), along with five known compounds. To the best of our knowledge, compound 1 is the first cyclic phenolic acid glycoside dimer.
对 Gentiana loureirii 整个植物的进一步化学研究导致了三种新化合物的分离和表征,环状 4-O-β-<小>D小>-吡喃葡萄糖基咖啡酸二聚体 (1),一种新的 α-四氢萘酮, 4-羟基-6-甲基-α-四氢萘酮4-O-β-<小>D小>-吡喃葡萄糖苷(2)和3β,30-二羟基-12-ursen-28-oic酸28-O- β-<小>D小>-吡喃葡萄糖酯 (3),以及五种已知化合物。据我们所知,化合物1是第一个环状酚酸苷二聚体。
