“…Finally, skin samples were collected, cleaned with phosphate buffer, and then homogenized with methanol to extract BIM that remained in the skin. Skin homogenate was then centrifuged at 10000 rpm for 15 min and BIM content in the supernatant was quantified by HPLC analysis as previously described ( Zezula et al, 2019 ). Briefly, HPLC system (Shimadzu, Kyoto, Japan) fitted with a Hypersil® C-18 column (1.5 cm × 4.6 mm, 5 μm) was employed.…”
