Long chain saturated hydrocarbons were isolated from petroleum ether extract of Momordica dioica Roxb. Ex Wild (Cucurbitaceae) fruits. The petroleum ether extract of fruits was subjected to silica gel column chromatography using petroleum ether (100%) as mobile phase. The isolated hydrocarbons fraction was characterized by gas chromatography mass spectroscopy (GCMS), along with IR, 1HNMR and 13CNMR spectroscopic techniques. Major compounds present in hydrocarbon fraction were tridecane (C13H28) at a retention time (RT) of 10.8 min, tetradecane (C14H30) at RT of 12.5 min, pentadecane (C15H32) at RT of 14.1 min, hexadecane (C16H34) at RT of 15.6 min, octacosane (C28H58) at RT of 26.2 min, nonacosane (C29H60) at RT of 26.5 min and tetratriacontane (C34H70) at RT of 26.7 min.
