Abstract

This article records for the first time the isolation of Ursolic acid from the leaves of (Roxb.) Bosser (Family: Rubiaceae) using ultrasonic waves. This bioactive triterpenic acid was isolated without its isomer, oleanolic acid, in a very convenient way with good yield. The structure was identified by means of one dimensional Nuclear Magnetic Resonance (NMR) spectroscopic techniques like H NMR, C NMR, distortionless enhancement by polarization transfer (DEPT) and two dimensional NMR spectroscopic method for example, heteronuclear single quantum coherence (HSQC). It was also assayed for antidiabetic and antioxidant potencies. About 71.5 mg of pure ursolic acid was isolated from 2.6 grams of ethyl acetate soluble fraction using sono-maceration as an extraction technique.
