  摘要：

  Two new neolignan glycosides, named pittogoside A (1) and pittogoside B (2) were isolated from the roots of Pittosporum glabratum Lindl. Their structures, including the absolute stereochemistry, were determined on the basis of spectroscopic analysis and chemical evidence, with combination of circular dichroism.
