Abstract

A new bisbenzopyran (1) has been isolated from the methanolic extract of roots of Aloe barbadensis through solvent separation and vacuum liquid chromatography. Based on spectral analysis including 2D-NMR (COSY, NOESY, J-resolved, HMQC, and HMBC) techniques, the structure of compound 1 was assigned as 3,3′-bis(3,4-dihydro-4-hydroxy-6-methoxy-2H-1-benzopyran).
