摘要

A new alkaloid, perlolyrine, 1-(5-hydroxymethyl-2-furyl)-9H-pyrido [3, 4-b] indole (6b), has been isolated from Lolium perenne L.(Graminae). The structure of the base was revealed by an X-ray analysis of its hydrobromide dihydrate C16H12N2O2, HBr, 2H2O (space group P, a= 7· 81, b= 10· 55, c= 10· 55 Å, α= 79· 2 β= 72· 9, γ= 78· 8°), by use of the heavy-atom method, assisted by spectroscopic data. The final value of R over 2360 reflections is 0· ...
