Abstract: Sorghum halepense (L.) Pers. is known as invasive weed in the world. In this paper we report three rare natural products from this weed. The compounds include a new rare natural product 2,2-dimethyl-5-(4-hydroxyphenyl)-4-oxazolidinone (1), and two other known mandelic acid derivatives, ethyl 4-hydroxymandelate (2) and 4-hydroxymandelamide (3). The structures of these compounds were elucidated by extensive spectroscopic analysis (MS, IR, 1H, 13C NMR and 2D NMR).
