Abstract
α-PICOLINE has been isolated from the leaves of the dock, Rumex obtusifolius L. There are isolated instances where pyridine and simple derivatives have been found to occur in Nature, for example, pyridine in Aplopappus hartwegi 1 and 3-methoxypyridine in Equisetum arvense 2. This would appear to be the first record of the presence of α-picoline in a natural source. The base was isolated in 0.1 per cent yield from an aqueous extract of the leaves and characterized as its hydrochloride (m.p. 200° anhydrous), picrate (m.p. 165–166°) and methiodide (m.p. 226–227°).
