Abstract

By silica gel, Sephadex LH-20 column chromatography as well as preparative high performance liquid chromatography (HPLC), four previously undescribed α-pyrones sharing same primary structure were isolated from the brown rice solid medium of Fusarium tricinctum. Their structures were elucidated by spectroscopic analyses and their absolute configurations were finally confirmed by a modified Snatzke's method.

Key words： 2-pyrone; Fusarium tricinctum; Ligusticum chuanxiong; induced circular dichroism
