ABSTRACT:Tagetes minuta L., commonly known as African marigold, is reputed as a source of ‘Tagetes oil’ of trade that finds an extensive use in food, flavoring, pharmaceutical, perfumery and cosmetic industry. In present study, variation in the essential oil content and composition of T. minuta grown in foot hills agroclimatic conditions of northern India and harvested in flower initiation, full flowering, late flowering and seed setting stages were compared and analysed using GC-FID and GC-MS. Essential oil content was found to vary from 0.52 to 0.78% in different growth stages of the crop. Altogether, 19 constituents, representing 81.2-93.9% of the total oil composition were identified. The essential oil composition was mainly dominated by monoterpenoids (80.5-92.9%) represented by (E)-ocimenone (31.8-42.2%), (Z)-β-ocimene (22.9-32.7%), (Z)-tagetone (8.0-11.0%), and (Z)-ocimenone (6.0-10.3%), dihydrotagetone (1.7-3.7%), (E)-tagetone (1.0-2.5%) and limonene (1.0-1.5%). The essential oil of T. minuta from foothills of northern India consist the constituents in entirely different quantitative composition.
