Echinacea (pronounced ek-a-NAY-sha) or purple coneflower is a perennial plant in the Compositae or daisy family (Foster, 1985). Traditional literature has reported that nine species of Echinacea exists in nature. However, under a new reclassification system, eight varieties are categorized under only four species (Binns et al., 2002a). Echinacea (E.) pallida var. angustifolia (hereafter referred to as E. angustifolia) and E. purpurea are the most common species of Echinacea. E. angustifolia is a wild flower in North...

The latter is the species most commonly found in herbal preparations (Tyler, 1993). 

Multiplet analysis is one of the most useful analytical tools in ID WIN-NMR it simplifies the measurement of coupling constants, it is the first step in disentangling overlapping multiplets of complex multi-spin systems and it provides the input parameters for the WIN-DAISY computer analysis program. It is based on the AX approximation and uses distance measurement to build up coupling patterns by recognizing lines split by a common coupling constant.

The species Xyloplax medusiformis and X. tumerae were found in pieces of wood found at great depth (1000-2000 m) off New Zealand and the Bahamas (Janies and Mooi, 1998), respectively. Subsequently, an undetermined species of Xyloplax was found at 2675 m in the North Pacific (Voight, 2005). Of circular shape and small size (about 1 cm in diameter), these organisms live exclusively on wood, hence their name, and their common name is sea daisies. ...
