Scutellarin (I) (yield 0.01 %), vicenin-2 (V) (yield 0.002 %), rosmarinic acid (VII) (yield 0.2%) and caffeic acid (VIII) (yield 0.005 %) were isolated and identified from the dried leaves of <I>Perilla frutescens</I> BRITTON var. <I>acuta</I> KUDO f. <I>viridis</I> MAKINO, a most popular garnish in Japanese cooking. Considering their yields, it was presumed that, of four above phenolics, rosmarinic acid plays a leading role in the harshness of this plant.<BR><I>Perilla frutescens</I> BRITTON var. <I>acuta</I> KUDO f. <I>viridis</I> MAKINO (Japanese name : Ao-jiso), annual herb of Labiatae, is well known as one of the most popular garnishes in Japanese cooking because of its excellent flavor. Some other features of this plant such as harsh taste and browning of leaf juice suggest the presence of phenolic constituents. However, so far the author is aware, they have not been examined chemically inspite of many papers concerning the origin of flavor. This paper deals with the isolation and identification of scutellarin, vicenin-2, rosmarinic acid and caffeic acid from its leaves.
