[Production of cinchona in the French empire: A. Yersin and E. Perrot].

In the wake of the war of 1914-1918, Professor E. Perrot and Dr A. Yersin were concerned with providing various territories of the French empire with sufficient cinchona resources to fight off malaria. This aim was particularly important in case of a conflict which could impede the supply of quinine due to the quasi-monopoly held by the Netherlands with their overseas possessions in Indonesia. Beginning with documents, in particular the correspondence held by the Museum of Materia Medica at the Faculty of Pharmacy in Paris, an attempt is made to illustrate the policy carried out with difficulty by Perrot and Yersin.

[Aromatic and polyphenolic composition of infused peppermint, Mentha x piperita L].

The qualitative and quantitative composition of the main aromatic and polyphenolic constituents of Mitcham type peppermint (Mentha x piperita L.) tisane, were examined and compared with those of leaves before and after infusion. The original peppermint leaves contained 2.4% essential oil of which menthol was 0.99%, total polyphenolic compounds 19% and total flavonoid compounds 12% comprising eriocitrin 7%, luteolin-7-rutinoside 1.5%, hesperidoside 0.6% and total hydroxycinnamic compounds 7% (rosmarinic acid 1.4%). The tisane contained 21% of the original essential oil corresponding to 25 mg/l, with increased alcohol and ketone contents and lower contents of hydrophobic terpenecarbons, oxides and esters. It contained also a high proportion of the polyphenolic compounds (about 750 mg/l) corresponding to an extraction yield of 75%. In consequence the monograph "Peppermint leaf" of the Pharmacopoeia should be amended.
