1. Introduction
The essential oils and extracts of aromatic plants and spices have been used in food preservation, pharmaceuticals, alter- native medicine and natural therapies. Currently, it is necessary to investigate those plants scientifically, for the composition of essential oil(EO) and its biological activities, which have been used in traditional medicine to improve the quality of health- care. The EO contents in different species are varied inherently, influenced greatly by culture conditions and environment, as well as by crop and post-crop processing, and hence evalua- tions of the oils from many medicinal plants are being con- ducted. One of the most useful EO bearing spices as well as medicinal plants is Coriandrum sativum L. (C. sativum) (con taining EO in its leaves, stem, flowers and fruits/seeds), and thus updates on its usefulness, based upon the scientific studies, are required for its better maintenance and scientific use for the mankind.
