The hydrodistilled waxy oils of the leaves and flowers of Catharanthus roseus (L.) G. Don cv. Nirmal plants grown at New Delhi were analysed by GC and GC–MS. A total of 52 compounds were identified, accounting for the 91.3% of the leaf oil. Among these the main constituents were as follows: ( E , E )‐2,4‐hexadienal (7.7%), citronellol (7.9%), geraniol (7.9%), p ‐cresol (4.7%), ( Z , E )‐pentadecanal (6.6%), hexadecanoic acid (4.9%), palmitic acid (4.9%) and phytol (6.4%). A total of 41 compounds were identified, accounting for 99.4% of the flower oil, whose main constituents were heneicosane (20.8%), tricosane (37.9%), tetracosane (6.1%) and docosane (4.3%).
