Fig 6. BOILED Egg model to predict GI absorption and brain permeability of the compounds identified from Terminalia catappa nuts.

Key: BBB; Blood-brain barrier (compounds that can penetrate BBB found inside yellow part of the egg), HIA; Human intestinal absorption (compounds that are absorbed by the human intestine in the white part of the egg), PGP⁺, P-glycoprotein substrate (blue circle on top of PGP+ substrates) and PGP^-; P-glycoprotein inhibitor (red circle on top of PGP^- inhibitors).
