Abstract

Abstract Mollugin was isolated from the extract of Rubia tinctorum roots. Lucidin was obtained by semisynthesis from xanthopurpurin. Mollugin crystallises in space group P-1 (No. 2), a= 8.5857 (7), b= 11.473 (4), c= 15.024 (1) Å, α= 77.64 (2)∘, β= 89.36 (1)∘, γ= 89.71 (2)∘, and V= 1445.5 (5) Å 3, lucidin crystallises in space group P 2 1/c (No. 14), a= 16.800 (6), b= 9.637 (2), c= 7.073 (7) Å, β= 98.01 (5)∘, and V= 1134 (1) Å 3.
