Ellagitannins from Pomegranate Flower with Whitening and Anti-skin Photoaging Effect.

A new depside glucoside rosarugoside E (1), together with four known compounds punicalagin (2), corilagin (3), granatin B (4) and ellagic acid (5) were isolated from the ethanol extract of pomegranate (Punica granatum L.) flower. Their structures were identified based on careful analysis of various spectral data including UV, IR, HR-ESI-MS, 1D and 2D NMR.

4,5-Dihydro-3a,5a-diazo-niapyrene triiodidocuprate(I).

In the dianion of the title salt, (C(14)H(12)N(2))[CuI(3)], the Cu(I) atom is coordinated by three I(-) ions that define a nearly trigonal-planar geometry; the Cu(I) atom lies 0.1407 (6) Å out of the plane. With the exception of the methyl-ene C atoms, the dication is essentially planar (r.
