IRIDOID AND EUGENOL GLYCOSIDES FROM NEPETA-CADMEA

From the aerial parts of Nepeta cadmea, a new iridiod glucoside, 1,5,9 -epideoxyloganic acid glucosyl ester, and a new eugenyl glucoside were isolated, together with the known compounds, 1,5,9-epideoxyloganic ac id, eugenyl-O-beta-D-glucoside, icarisides B-1 and B-2, (6S,9S)-roseos ide, lariciresinol-4'-O-beta-D-glucoside and rosmarinic acid. Sodium a nd potassium salts of 1,5,9-epideoxyloganic acid were also isolated. T he structures of newly isolated compounds were elucidated by spectral and chemical analyses.
