Secondary metabolites from <i>Nepeta juncea</i>

Abstract

The study of the phytochemical investigation on the chemical constituents of the whole plant of Nepeta juncea belonging to the family Lamiaceae resulted in the isolation and characterization of 11 compounds. Nine of these compounds were identified as ursolic acid, oleanolic acid, β-sitosterol, stigmasterol, stigmasterol glucoside, 5,4'-dihydroxy-3,6,7-trimethoxyflavone, (-)-6β-hydroxy-15,16-epoxy-5β, 8β, 9β,10α-cleroda-3,13(16),14-trien-18-oic acid, glutinol and β-amyrin. These compounds were individually identified by different spectroscopic techniques and by comparisons with reported data. This study constitutes the first phytochemical work on Nepeta juncea.
