Nevertheless, it may be seen (Table 11) that the intercept obtained (and therefore the purity evaluated) is not markedly influenced by the choice of activ

✦ Synopsis
A large number of opium alkaloids has been chromatographed by gas, thin-layer, and paper chromatography for the purpose of identification. Gas chromatography is particularly valuable because of its speed, sim licity, and reproducibility. T h e two other methods are useful for certain alkaloi& which either d o not lend themselves t o gas chromatography or give unsatisfactory separation. EW NATURAL products have been studied so ex-Rec.eived May 16,1964, from the School of Pharmacy,
