Abstract

Spermacocelatifolia (family: Rubiaceae) is one of the important members of the medicinal plants of Bangladesh. Compounds: stigmasterol (1), 2,6-di-t-butyl-4-hydroxymethylene-cyclohexa-2,5- dienone (2), 3β-hydroxy-12-oleanen-28-oic acid (3) and phthalic acid (4) have been isolated from the aerial parts of S. latifolia. Compounds (1), (2) and (3) were isolated from the chloroform extract but compound (4) was isolated from the methanol extract. The structures of the compounds have been established by different spectroscopic data analysis. All four compounds were isolated from this plant for the first time.

Keywords: Spermacocelatifolia, isolation, structure elucidation, spectroscopic methods.
