抄録

Leaves and bulb of Allium tuberosum Rottl. (A. odorum L.) and the bulb of leek (A. Porrum L.) were extracted with alcohol and the reaction products of these extracts with thiamine were examined by paper chromatography. The former plant was found to yield allithiamine (IV) and its methyl homolog (VIII), while the latter failed to yield these derivatives. In the case of A. tuberosum, (IV) and (VIII) were obtained as crystals and their formation confirmed.
