A new biocompatible microemulsion increases extraction yield and bioavailability of Andrographis paniculata

As a new drug carrier, the biocompatible microemulsion (BM), which containing lecithin and bile salts showed a good physical stability, the BMAP containing more fat-soluble and water-soluble ingredients was prepared when using BM to extract Andrographis paniculata. Compared with the ethanol extract of AP, the bioavailability of andrographolide extracted by BMAP was significantly higher.
