Antiviral Ability of Kalanchoe gracilis Leaf Extract against Enterovirus 71 and Coxsackievirus A16
Figure 1
HPLC fingerprint profiles and UV/vis absorption spectra of K. gracilis leaf extract of ethyl acetate layer and marker components. Marker components of ferulic acid, quercetin, and kaempferol (a) and K. gracilis leaf extract of ethyl acetate layer (b) were analyzed using HPLC with a C-18 reverse phase column. Eluents were detected at 360 nm. Maximum absorption wavelengths of ferulic acid, quercetin, kaempferol, and chromatographic peaks 5, 12, and 15 were measured by UV/vis absorption spectra (200–360 nm).
