Isolation and photoisomerization of a new anthraquinone from hairy root cultures of Sesamum indicum.
An unstable anthraquinone was isolated from hairy root cultures of Sesamum indicum after preventing light throughout all experimental procedures. The structure of the (Z)-isomer of a previously isolated anthraquinone was determined to be 2-[(Z)-4-methylpenta-1,3-dien-1-yl]anthraquinone by spectroscopic methods. This compound was readily isomerized to the known (E)-isomer under light.
