The flowers of Sesbania grandiflora (Linn.) Pers. afforded a 3:2 mixture of β-stigmasterol (1a) and β-sitosterol (1b), and oleanolic acid (2), while the leaves of Heliotropium indicum Linn. yielded β-carotene (3), lutein ( 4), a mixture of polyprenols (5), and a mixture of β-stigmasterol and β-sitos...
