Zusammenfassung:	Rosemarinic acid or its concentrate is made from seeds of lamiaceous plants in a predetermined period of germination. The method makes it possible to make the rosemarinic acid in any period through the year. High productivity can be achieved by small production facility since high-density cultivation of germinated seed is possible and a cultivation period is short. An amount of rosemarinic acid is rapidly increased after start of germination, and an increasing amount usually becomes maximum five to eight days after start of cultivation. Power obtained by pulverizing dry germinated seeds contains 3 to 5% of rosemarinic acid and can be used for various purposes. An extract obtained by water soluble alcohol from the powder and a fraction obtained by fractioning the extract by an organic solvent are concentrated containing about 15% and 30% of rosemarinic acid respectively. When each concentrate is processed by column chromatography, isolated 99%-rosemarinic acid is obtained.
