Chemical constituents of Polyscias nodosa

Chemical investigation of the dichloromethane extracts of Polyscias nodosa (Bl.) Seem. yielded squalene (1), phytyl fatty acid esters (2), lutein (3), and β-sitosteryl-3β-glucopyranoside-6'-O-palmitate (4) from the leaves; and 1, triacylglycerols (5), and a mixture of stigmasterol (6a) and β-sitosterol (6b) in a 5:1 ratio from the twigs. The structures of 1-6b were identified by comparison of their NMR data with those reported in the literature.
