Visually, the size and shape of the leaves varies greatly, from the large lettuce-like leaves of the "Mammoth basil" and "Lettuce leaf basil" to the tiny leaves of the "Dwarf bush basil". More practically, the fragrance of the basil varies due to the varying types and quantities of
essential oil s contained in the plants. The most important are 1,8cineol ,linalool ,citral , methyl chavicol (estragole ),eugenol andmethyl cinnamate , although hardly any basil contains all of these in any significant amount.References
