Phytochemical Screening and Characterization of Olean-18-ene Type Triterpeniod from the Roots of Lantana camara

Abstract

Lantana camara, commonly called wild or red sage or sleeper weed is the most widely spread species of the genus Lantana traditionally used to treat various diseases such as diarrhea, fever, and stomachache. It has also been reported to show antifungal, antiproliferative, insecticidal, antimicrobial and germicidal activity. Phytochemical screening of the methanol extract revealed the presence of flavanoids, terpenes, saponins and the absence of anthraquinones and alkaloids Silica gel column chromatographic separation of the methanol root extract yielded an olean-18-ene type triterpene. Complete characterization of the isolated compound was done using spectroscopic techniques (UV-Vis, IR, ¹H-NMR, ¹³C- NMR, DEPT-135, COSY, HMBC and HSQC).
