  1. a HEX, hexane; DCM, dichloromethane; MeOH, methanol.
  2. b Strong (+++), moderate (++) and weak (+) presence, and absent (-). Classification was based on observation of colour intensity and amount of precipitate.
  3. c Saponins, tannins, cardenolides and terpenoids were screened using the frothing, ferric chloride, Kedde and vanillin-H2SO4 tests.
