Argolic Acid A and Argolic Methyl Ester B, Two New Cyclopentano-monoterpenes Diol from Nepeta Argolica

“…Some species of this genus are important medical plants and they have euphoric effects on cats [2]. Many species of the genus have been investigated and found to contain monoterpenoids, diterpenoids and triterpenoids [3][4][5] N. cataria L. (catnip), the most thoroughly studied species, is used in folk medicine as diuretic, carminative, antispasmodic, emmenagogue and sedative [6,7]. N. argolica Bory et chaub.…”
