Seven resorcylic acid lactones (RALs) including five new analog rhinoclactones, A–E (1, 2, 4–6), were isolated from an endophytic fungus Rhinocladiella similis in the plant Agriophyllum squarrosum collected from the Tengger Desert of the Ningxia Province, China. The structures of these new compounds were determined by HR-ESI-MS (High Resolution Electrospray Ionization Mass Spectrometry), NMR data, modified Mosher’s method, and X-ray diffraction experiments. All compounds isolated from this fungus possessed the 16-OMe/14-OH, not the common 16-OH/14-OH or 16-OH/14-OMe groups on the aromatic ring, which are rarely found in nature. Compound 7 displayed cytotoxic activities against HCT116 and HeLa cancer cell lines. The possible biosynthesis of 1–7 is suggested, and the potential ecological roles of these fungal secondary metabolites is discussed.

Two new resorcylic acid lactones, 13-hydroxyhidroresorcylide (1) and 12-hydroxyhidroresorcylide (2), along with four known congeners (3–6) were isolated from Saccharicola bicolor, an endophytic fungus from Bergenia purpurascens. Their structures were elucidated by interpretation of the spectroscopic evidence.

ABSTRACTThe nature of collisions within ring systems is reviewed with emphasis on Saturn's rings. The particles may have coherent icy cores and less coherent granular or frosty surface layers, consistent with thermal eclipse observations. Present-day collisions of such ring particles do not cause catastrophic fragmentation of the particles, although some minor surface erosion and reaccretion is possible. Evolution by collisional fragmentation is thus not as important as in the asteroid belt.
