Two other commonly found sources of caffeine (16) are kola Cold) from the seeds of, for example. Cola nitida (Vent.) Schott and Engl., which contains 1—4% of the alkaloid, but Httie theophylline or theobromine, and cocoa (from the seeds of Theobroma cacao L.), which generally contains about 3% theobromine and significantiy less caffeine.

Forms yellow plates from AcOH, and needles from EtOH [Slotta and Szyszke Chem Ber 68 184 7955]. With diazomethane,. 5-nitro-3,4-dimethoxyacetophenone is formed [Brady and Manjunath J Chem Soc 125 1067 1924]. The methyl ether crystallises from EtOAc or AcOH, m 88", 90-91", and the phenylhydrazone has m 108-110° (from aqueous EtOH).

Although Eqs. (14.2) and (14.4) can be solved analytically (as will be shown in the next section), here it is sufficient to use the renowned depletion, or Schott-ky approximation, in which it is assumed that the effective density of chaige is constant and equal to qNd in the depletion region, and zero outside this region. In this case, a double integration of Eq. (14.2) directly gives...
