Almost all the wild plant species are capable of producing oils, which can be used in the manufacture of perfumery, cosmetics and medicine. The oils may be volatile substances of vegetable origin with a distinctive odour or flavour. The utility of these vegetable oils should be explored, after knowing their economic concentration in plants and after eliminating the toxic principles present, if any. This paper deals with the oil contents of different plant species which are unconventional sources of oil.
