Physico-chemical properties of methyl 5-hydroxy-dinaphtho[1,2-2'',3''] furan-7, 12-dione-6-carboxylate(MHDDC) were examined. The yellowish color of the solution at pH 8 below changes to a bluish color when the solution is basified to pH 10 above. This color change was presumed to a change of the molecular structure from a quinoid-type to a quinoid-type with the dissociation to the hydroxyl group as shown in chart 1.

UV and high performance liquid chromatographic methods for the quantitative analysis of methyl 5-hydroxy-dinaphtho [1, 2-2'', 3''] furan-7,12-dione-6-carboxylate(MHDDC) in urine and blood were developed. The correlation coefficients of the calibration curves of MHDDC in chloroform, methanol and dioxane solution were 0.999, 0.997 and 0.998, respectively. MHDDC was resolved within 15 min and had a detection limit of 2~5ng at S/N 3 by using a reversed-phase column with two solvents (MeOH, HAc).

The derivatives of methyl 5-hydroxy-dinaphtho[l,2-2'',3'']furan-7,12-dione-6-carboxylate (MHDDC) were synthesized by condensing alkyl sulfate or alkyl halide with MHDDC in organic solvent, and their structures were identified by NMR, MS, UV, IR etc. We also investigated the physico-chemical properties, physiological activities, and set up the micro-analytical method of the compounds.
