Terpenoids and sterols from Lagerstroemia speciosa.
The leaves of Lagerstroemia speciosa afforded a new natural product, 31-norlargerenol acetate (4), along with known compounds 24-methylenecycloartanol acetate (1), its 31-nor analog (2), largerenol acetate (3), tinotufolins C (5) and D (6), lutein, phytol, sitosterol and sitosterol acetate. The structure of 4 was elucidated by 1D and 2D NMR and mass spectroscopy.
