Three isoprenylated flavanones were isolated from the leaves of Flemingia lineata (L.) Aiton. Among them are two new flavanones, flemilineatins A and B (1 - 2), along with 6-isoprenyl eridioctyol (3). Their structures were determined using HRESIMS data and NMR spectra. Flavanones 1 - 3 were assayed in the HeLa cancer cells. Compound 1 showed moderate activity with an IC 50 value of 11.2 µM.
