Crude rectified spirit extract of the stem bark of Crataeva nurvala was taken under chemical investigation. The chloroform fraction yielded total four compounds namely betulinic acid (1), lupeol (2) and ß-sitosterol (3) and stigmasterol (4). The structure of the isolated compounds were established by extensive analyses of 1H NMR spectroscopy and compared the spectral data, melting points with the authentic specimen. The results indicate that the stem bark of Crataeva nurvala provide a rich source of triterpenoids and steroids.
