The investigation led to the characterization of five triterpenes, glut-5(6)-en-3β-ol (1), lupeol (2), betulin (3), betulinic acid (4) and betulinaldehyde (5). Their structures were determined on the basis of spectral analysis. Of these, betulinic acid, a potent anti-HIV agent, was found to be a major product. Glut-5(6)-en-3β-ol was a rare natural product.Cell suspension culture; Secondary metabolites; Solanum incanum L; Triterpenes[SDGs]SDG3anti human immunodeficiency virus agent; betulic acid; betulin; lupeol; natural product; triterpene derivative; article; carbon nuclear magnetic resonance; cell suspension; chemical composition; chemical structure; conformation; nonhuman; phytochemistry; proton nuclear magnetic resonancejournal article2-s2.0-0033753163
