  1. a Initial screening showed that extracts of Dyera costulata and Kopsia fruticosa did not show any APF activity.
  2. b GI50 (μg/ml) is growth inhibition (GI) of cancer cell lines by 50%. Inhibition is not effective (-) with values >20 μg/ml. MCF-7 and MDA-MB-231, HeLa and SKOV-3, HT-29, and HepG2 are human breast, cervical, colon and liver cancer cell lines, respectively.
  3. c HEX, hexane; DCM, dichloromethane; MeOH, methanol.
  4. d Data on standard drugs of xanthorrhizol, curcumin and tamoxifen against MCF-7 and MDA-MD-231 cell lines are from an earlier publication [24].
