<P>PROBLEM TO BE SOLVED: To provide an aqueous solution including in high content, the nitrogen-containing compounds contained in plants of Brassicaceae. <P>SOLUTION: The aqueous solution including the nitrogen-containing compounds is obtained by immersing the plants of Brassicaceae in an aqueous solution and extracting under an acidic condition. Since the nitrogen-containing compound can efficiently be extracted from the plant body of Brassicaceae by the above method, the compound specific to the above plant such as alkaloids can be obtained in high content. The plant preferable to obtain such aqueous solution is genus Lepidium, Brassicaceae, more preferably maca. <P>COPYRIGHT: (C)2007,JPO&INPIT |
