Abstract
Two new benzo-isochromenes, named cichorins B (1) and C (2), were isolated from Cichorium intybus. The structures of the new compounds were elucidated by detailed spectroscopic analysis such as ¹H, ¹³C NMR, COSY, HMQC, HMBC, and HR-EI-MS. Relative configurations of asymmetric centers of cichorins B and C were determined by the analysis of the ¹H NMR coupling constants together with the 2D NOESY and 1D NOE experiments as well as from [α]²⁵(D) value.Entities:
