Figure 3

UV spectra of 6-monodeoxy-6-monoamino-β-cyclodextrin⋅hydrochloride (6-NH2-β-CD⋅HCl), folic acid (FA), PTX, CDPF, CD-ic-PTX, and CDPF-ic-PTX monitored from 220 nm to 280 nm. The inclusion complex between CDPF and PTX made the specific absorption peak (228 nm) of PTX appear due to the improved water solubility of the drug.
