Figure 2

Chromatograms of Boswellia serrata extracts (BS) after HPLC-DAD analysis. BS (A)–(F) extracts were diluted 1 : 400 in methanol, whereas, BS (G) extract was diluted 1 : 20 in methanol. The chromatogram of the AKBA analytical standard is also reported (H). The absorbance (mAU) is reported on the -axis, wavelength (nm) on -axis, and the retention time (minutes) on the -axis.
