An erect, glabrous or minutely pubescent, branched annual. The stems are striate; the leaves are rather distant, 2-3-pinnately divided, the segments linear. The flowers occur in terminal or seemingly-lateral pedunculate, compound umbels, white and small; the fruits are ovoid, muricate, aromatic cremocarps, greyish brown; the mericarps, which are the components of the fruit, are compressed, with distinct ridges and tubercular surface, 1-seeded.
The alcoholic extract was found to contain a highly hygroscopic saponin, with a hemolytic index of 500. A yellow, crystalline flavone (m.p. 291-94°) and a steroidal substance (m.p.140-50°) have also been isolated from the fruits1
. The principal constituents of the essential oil from the fruits are the phenols, mainly thymol and some carvacrol. The Indian Pharmacopoeia requires ajowan oil to contain not less than 40 per cent thymol. The remainder of the oil is called 'thymene'. Thymene, which constitutes c.45 per cent of the oil, has the following composition: p-cymene, 50-55; g-terpinene, 30-35; a- and ß-pinenes, 4-5; and dipentene, 4-6%. Presence of minute 'amounts of camphene, myrcene and D3-carene is also reported2
