Arjunolic acid (an oleanane-type triterpenoid) and asiatic acid (an ursane-type triterpenoid) were obtained as an inseparable mixture from a chloroform extract of stem-bark of Eugenia grandis (Myrtaceae). They were characterised mainly by analysis of their spectral data. Arjunolic acid and asiatic acid are reported to have a variety of biological and pharmacological activities, which include antibacterial, anti-inflammatory, antioxidant, antidiabetic, antihyperlipidemic, cardiacprotective, antitumor, anticancer and hepatoprotective activities. Arjunolic acid has been used as a cardio-protective phytotonic in traditional Ayurvedic medicine for centuries.
