Nepetalactones and Other Constituents of Nepeta nuda ssp. Albiflora

The hexane extract of Nepeta nuda ssp. albiflora led to the isolation of six known monoterpene nepetalactones, 4aa,7a,7aa-nepetalactone (1), 4aa,7a,7ab-nepetalactone (2), 4ab,7a,7ab-nepetalactone (3), 4ab,7a,7aa-nepetalactone (4), 4aa,7b,7ab-nepetalactone (5), 3a-hydroxy-4aa,7a,7aa-dihydron\-epe\-tal\-actone (=nepetalic acid) (6) and a dimeric 5,9-dehydronepetalactone (7) along with two known steroids b-sitosterol and sitosterol 3-one and a triterpene betulinic acid. The acetone extract of the same plant afforded compound 7 in a higher yield in addition to compounds 2 and 6, and sesquiterpene caryophyllene oxide, the iridoid glucoside 1,5,9-epideoxyloganic acid, the triterpenoids oleanolic, ursolic and betulinic acids, and sitosterol 3b-glucoside.
