%X A new pigment, dianellinone, has been isolated from the roots of Dianella revoluta and Stypandra grandis in yields of 0.09 % and 0 025 % respectively. S. grandis also contains a second pigment, stypandrone, which has been identified as 6-acetyl-5-hydroxy-7-methyl-1,4-naphthoquinone. Chemical and spectroscopic evidence indicates that dianellinone is the corresponding 3,3'-dinaphthoquinone.
