“…A derivatization using dansylhydrazine and hydrochloric acid was employed for 4-OHCP; this method used ethyl acetate for extraction and a C18 column for separation. The SPE method was adopted for the extraction of CP, doxorubicin, and doxorubicinol and CP, paclitaxel, docetaxel, vinblastine, vinorelbine, pemetrexed, carboplatin, etoposide, ifosfamide, gemcitabine, irinotecan, and SN-38 from human plasma samples(Gao et al, 2018).A simultaneous quantification of CP, thalidomide, lenalidomide, bortezomib, dexamethasone, and adriamycin in human serum samples was achieved using LC-MS/MS positive ionization mode(Shu et al, 2016). Various analytes were separated by a gradient elution using a C18 column at a flow rate of less than 0.3 mL/min Zhou et al (2012).…”
