Abstract

Morinda pubescens var.pubescens (Rubiaceae) is a tropical plant whose leaves, bark, roots and fruits have been used as traditional remedy for various diseases. In our study we identified four Known compounds as two Pentacyclictriterpenoids Ursolic acid and Taraxerol‚ two sterols β-Sitosterol and Stigmasterol from Morinda pubescens var. pubescens (Rubiaceae). Solvent extraction‚column chromatography were major techniques used for isolation of compounds, while structures were elucidated by integration of data from IR,UV, 1H NMR AND 13C NMR analysis. We are reporting presence of Taraxerol a pentacyclictriterpenoid first time from the leaves of Morinda pubescens var. pubescens of Rubiaceae family.
