3.3.2 Linearity and LLOQThe typical regression equations, correlation coefficients, linear ranges and LLOQs of all analytes are shown in Supporting Information Table S1. The LLOQ for geniposide, genipin gentiobioside, honokiol, magnolol, isonaringin, naringin, hesperidin, neohesperidin were 10, 5, 1, 5, 1, 5, 1 and 5 ng/mL, respectively, which were sufficient for the pharmacokinetic study
