Natural Product Identification

Common Name

Rishitin

Description

Rishitin belongs to the class of organic compounds known as 1,2-diols. These are polyols containing an alcohol group at two adjacent positions. Studies using radioisotope labeled compounds, revealed however that solavetivone, 15-hydroxysolavetivone, lubimin and 3-hydroxylubimin are precursors of rishitin. Rishitin is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, Rishitin has been detected, but not quantified in, several different foods, such as potato, pepper (c. Annuum), orange bell peppers, red bell peppers, and green bell peppers. This could make rishitin a potential biomarker for the consumption of these foods. Same as the phytoalexin capsidiol, it belongs to the group of sesquiterpenes and is as such a FPP derivative. The biosynthetic pathway of rishitin has not yet been fully elucidated, and is still an active topic of research. Currently, the enzymes responsible for the synthesis of rishitin have not yet been discovered. Rishitin was named after the potato cultivar Rishiri, where it was first discovered in 1968. Rishitin belongs to a heterogeneous group of anti-microbial plant defense compounds termed phytoalexins and is produced upon pathogen attack. Rishitin is found in Nicotiana tabacum , Boeremia exigua, Phytophthora infestans, Solanum demissum, Solanum spp and Solanum spp.. Rishitin is a terpenoid compound, produced by some plants belonging to the Solanum family, including potato and tomato.
