Abstract

The triterpene, lup-20(29)-en-3-ol (lupeol) was isolated from the Nigerian medicinal plant Lonchocarpus cyanescens Benth. The structure elucidation was carried out by using m.p., [α]_D,IR, ¹H and ¹³C NMR, and MS. The assignment of carbon spectral data was made by DEPT and the 2-Dimensional ¹³C-¹³C Autocorrelated Double Quantum Coherence technique (Autocorrelated 2D-DQC spectroscopy).
