Serjania goniocarpa is a plant used in Mayan traditional medicine as a remedy for the treatment of cancer-like symptoms. Bio-guided fractionation of the methanol extract of the leaves led to the isolation of an α- and β-amyrin mixture, palmitic acid, phytol and the new sesterterpene goniocarpic acid whose structure was elucidated by IR, GC-MS, and NMR spectroscopic analyses. Goniocarpic acid exhibited cytotoxic and antiproliferative activity against several cancer cell lines.
