The essential oil content and composition of "sweet marjoram" (Ma- jorana hortensis Moench.) cultivated in the Kumaon region of the w estern Hi- malayas was studied at different ages of the crop. The samples were taken after 60, 90, 120 an d 150 day s of transplanting. The esse ntial o il contents vari ed from 0.20 to 0.70 %. The essential oil was analyzed by GC and GC-MS. Twenty eight components, representing 96.53-98.44 % of the oil, were identified. The major essential oil co nstituents, viz., cis-sabinene hy drate ( 37.05-47.49 %), terpinen-4-ol (14.45-16.22 %) and trans-sabinene hydrate (5.81-6.97 %) showed considerable variation in their concentrations in relation to crop age.
