Bioavailability

Protopanaxatriol and protopanaxadiol exhibit limited oral bioavailability due to the poor solubility and intestinal cytochromes P450-mediated metabolism. The aim of this study was to fabricate 20(S)-protopanxadiol (PPD) nanocrystals to improve PPD's oralBioavailability and brain delivery.
