Chemical constituents from the leaves of Elaeocarpus floribundus.

The genus Elaeocarpus belongs to the Elaeocarpaceae family, consists of about 350 species distributed in the tropical and subtropical regions. Plants in the genus, reportedly, contain compounds known for various biological activities like affinity for the δ-opioid receptor, antioxidant, cytotoxicity and antimicrobial activities. Elaeocarpus floribundus, commonly known in India as 'Indian Olive' is a medicinal plant widely distributed through Eastern Asia and the pacific. Here, we report the isolation and spectroscopic characterization of fifteen compounds (1-15) and additional three compounds (16-18) were obtained as mixtures. This includes four fatty acids, three diterpenoids, one triterpene alcohol, two fatty alcohols, three phaeophytins, one phytosterol, one sesquiterpene, and three hydrocarbons from the hexane extract of the leaves. Compounds 1-18 are reported for the first time from this source. To the best of our knowledge, this is an initial report of the isolation of compounds 1-11, and 14-18 from the genus Elaeocarpus.
