Nine new complex flavanones, cryptometcones A-I (-), along with four known analogues, were isolated from . The structures of - including their absolute configurations were elucidated by spectroscopic data analysis and electronic circular dichroism (ECD) calculations. In addition, the structure of oboflavanone A was revised, while the absolute configurations of oboflavanone B, cryptoflavanone C, and cryptoflavanone D were determined, according to their spectroscopic data. Compounds -, , and exhibited cytotoxicity against the HCT-116 cancer cell line.
