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) Å³, lucidin crystallises in space group P2₁/c (No.14), a = 16.800(6), b = 9.637(2), c = 7.073(7) Å, β = 98.01(5)^∘, and V = 1134(1) Å³.

Keywords:	Madder root mollugin lucidin Rubia tinctorum
