Figure 1: Thin-layer chromatography chromatogram of Astraeus odoratus and Astraeus asiaticus extracts. Thin-layer chromatography was detected under UV 254 nm (a); and by spraying with 10% H₂SO₄and heated (b). Two additional bands of Astraeus odoratus extracts were shown (arrows). Lane 1: 95% ethanolic extract of Astraeus odoratus; lane 2: 95% ethanolic extract of Astraeus asiaticus; lane 3: hexane layer of Astraeus odoratus or AO in this study; lane 4: hexane layer of Astraeus asiaticus or AA in this study; lane 5: ergosterol
