Ipomoea carnea is a weed found in northeast India, particularly in Assam and West Bengal. The weed has high regenerative capacity and propagates through seeds and wood cuttings, making it difficult to eradicate. Prasenjit Saikia from Coal Chemistry Division of the CSIR-North East Institute of Science and Technology in India produced and characterized oil produced from weed species Ipomoea carnea and evaluated it for use in biofuel production.

Oil was produced from Ipomoea carnea through thermal pyrolysis with maximum oil yield obtained at a pyrolysis temperature of 550 °C. The oil was characterized and its H/C molar ratio was revealed to be comparable with petroleum-derived diesel. However, the presence of oxygen (35.86%) in the form of oxygenates makes the oil acidic, which needs to be upgraded for use in the current IC engine.
