Abstract:
Three samples of Boswellia occulta gum resin (Grades I, II and III) were analyzed by GC-MS and GC-FID. Fifty constituents could be identified, and several of them were isolated by flash chromatography and characterized by NMR. The combinatorial synthesis of homologous series of reference constituents permitted the unambiguous identification of five 1-methoxyalkanes and one 1-methoxyalkene. In addition, we measured the 14C content of one sample of essential oil and of a methoxyalkanes rich fraction and demonstrated that the origin of these materials is totally natural.

Graphical and Analytic Representation of Sinusoids
The first step is measuring the peak-to-peak value, which is twice the amplitude of the sinusoid. This provides information about the maximum voltage swing of the waveform.
Secondly, the period and angular frequency are determined. The period is the time taken for one complete cycle of the waveform, while...
