(Furan-2-yl)[(furan-2-yl)carbonyl-disul-fanyl]methanone.

The mol-ecule of the title compound, C(10)H(6)O(4)S(2), has crystallographically imposed twofold symmetry. The dihedral angle formed by the furan rings is 80.90 (8)°.

[Determination of the contents of resveratrols and piceids in wines by high performance liquid chromatography with solid phase extraction].

A method has been developed for the determination of the contents of cis- and trans-resveratrols and piceids in wines by high performance liquid chromatography (HPLC) with solid phase extraction (SPE). The techniques of SPE including the activation of the SPE column, elimination of interference and elution conditions of samples were confirmed. The analytes were separated by using a Hypersil C18 column (4.
