Fig. 2From: Acetylmelodorinol isolated from Sphaerocoryne affinis seeds inhibits cell proliferation and activates apoptosis on HeLa cellsIsolation and identification of AM from SAS-EA. a Viability of Hela cells cultured with fractions E2 to E8 at concentrations of 50, 25, and 12.5 µg/mL for 48 h. E4 exhibited the strongest inhibitory effect on HeLa cell proliferation. AM was isolated from E4. b Chemical structure of AM was identified using ESI-TOF–MS.
