New potential oilseed crops for industrial uses have been considered for agronomic traits and seed oil composition during last decades in different countries. In order to extend the knowledge of phytochemical biodiversity of higher plant lipids, seed fatty acid compositions of Putranjiva roxburghii (Euphorbiaceae) were investigated. This research was conducted to evaluate changes in the contents of oil and fatty acids of P. roxburghii seeds obtained from different maturity stages. Oleic and linoleic acids were found as abundant compounds
