Solanaceae, known as “nightshade family”,has a worldwide distribution in all the continents except Antarctica. The greatest diversity is found in South America and Central America. This family includes important agricultural crops, medicinal plants, spices, weeds, and ornamentals. Potato (Solanum tuberosumL.), tomato (Solanum lycopersicumL.), pepper (Capsicum annuumL.) and egg plant (Solanum melongenaL.) are primary food species. Many other species produce alkaloids, are used in pharmacology and medicine (Nicotiana L., Hyoscyamus L.,and DaturaL.). There are several poisonous species, including Deadly Nightshade (Atropa belladonnaL.), Henbane (Hyoscyamus nigerL.) and Thorn Apple (Datura stramoniumL.), and the family also contains the important economic plant, Tobacco (Nicotiana tabacumL.), which contains the highly toxic alkaloid “nicotine”.
