Laggera crispata (Vahl) Hepper & Wood (Asteraceae), Cyclospermum leptophyllum (Pers.) Eichler (Apiaceae) and Perilla frutescens (L.) Britton (Lamiaceae) are under-explored aromatic plants of western-Himalaya. The hydrodistilled essential oils of L. crispata, C. leptophyllum and P. frutescens were analyzed using gas chromatography-flame ionization detector (GC-FID) and GC-mass spectrometry (GC-MS) and tested against nine pathogenic bacterial strains using disc diffusion assay. Major constituents of L. crispata essential oil were 2,5-dimethoxy-p-cymene (43.2 %), 10-epi-γ-eudesmol (19.7 %), eudesm-7(11)-en-4-ol (4.8 %), α-humulene (3.8 %), 7-epi-α-eudesmol (3.6 %) and (E)-caryophyllene (3.5 %). Major constituents of C. leptophyllum oil were 2,5-dimethoxy-p-cymene (46.8 %), thymol methyl ether (14.6 %), p-cymene (13.9 %), γ-terpinene (8.9 %) and carvacrol methyl ether (7.5 %). However, the essential oil of P. frutescens contained perilla ketone (48.6 %) and isoegomaketone (32.1 %) as main constituents...
