Kim and coworkers isolated a new neolignan, piperkadsin C, and elucidated its structure. However, the structure was revised by the same group in their next article. Structure Elucidator Suite was used to confirm the proposed structure #2, molecular formula C20H20O6.

The highly coveted Gaussian peak, a sharp symmetrical shape on a flat baseline, is the ideal peak shape in chromatography. Why is it so highly desired? Naturally, we tend to be drawn to the beauty of symmetry, but more importantly, good peak shape is important for better resolution (Rs) and increased accuracy in quantitation.
