Chemical Constituents of Artocarpus altilis and Artocarpus odoratissimus

Chemical investigation of the dichloromethane extract of the leaves of Artocarpus altilis yielded βsitosterol (1), unsaturated triglycerides (2), squalene (3), polyprenol (4), lutein (5) and unsaturated fatty acids. The structures of 1-5 were identified by comparison of their 1 H and/or 13 C NMR data with those reported in the literature. Chemical investigation of the dichloromethane extract of Artocarpus odoratissimus afforded 1, 2, and unsaturated fatty acids from the flesh of the fruit and seeds; and 1, unsaturated fatty acids and hydrocarbons from the fruit rind.
