Essential oils, flavors, and spices constitute a large and heterogeneous group of substances to which humans are exposed. The essential oils are defined as a group of odorous principles soluble in alcohol and only to a limited extent in water. They consist of a mixture of esters, aldehydes, ketones, and terpenes. Relatively few members of this group of sub stances have been shown to cause cance...

Piper hispidinervum (C. DC.), Piperaceae, is a promising source of sassafras oil, the source of safrol, currently derived from endangered plants of the Lauraceae such as Ocotea pretios Ness (Mez.), Cinamomum petrophilum, C. mollissimum, and Sassafras albidum Nutt. The essential oil of P. hispidinervum contains high levels (83–93%) of safrole in leaves which can be easily extracted by hydrodisti...

Plant essential oils are complex mixtures of volatile organic compounds, which play indispensable roles in the environment, for the plant itself, as well as for humans. The potential biological information stored in essential oil composition data can provide an insight into the silent language of plants, and the roles of these chemical emissions in defense, communication and pollinator attracti...
