Natural products – Discover their challenge and beauty
Natural products have always been among the most fascinating objects of the
practicing chemist. In fact, in many definitions of chemistry the isolation, purifi
cation and structural elucidation of natural products plays a central role. The his

Most analytical experiments produce measurement data which require
to be presented, analysed, and interpreted in respect of the chemical
phenomena being studied. For such data and related analysis to have
validity, methods which can produce the interpretational information
sought need[r]

Sorghum commonly is eaten with the hull (the outer layer of the grain), which retains the majority of the nutrients. Sorghum has excellent chemical and physical properties, which make it a grain of good quality for processing different types of products. The nutrient composition of sorghum grain ind[r]
