摘要
The tunicate Aplidium longithorax collected from Palau contained two novel prenylated paracyclophane-and metacyclophane-type hydroquinones, longithorols A (1) and B (2), in addition to longithorones A-I. Longithorols A and B were very unstable and were therefore isolated as their more stable pentaacetate farms, 3 and 4, respectively. The structures of 3 and 4 were determined by spectral data, especially 2D NMR data.
