Normalized soluble protein content per spheroid (µg) of the sodium alginate encapsulated LS180 mini-tumor model, following 96 h exposure to Xysmalobium undulatum aqueous extract or paclitaxel. The solid black line represents the untreated control, the black dashed line represents paclitaxel [IC50], the orange line represents X. undulatum [IC50] and the blue line X. undulatum 2[IC50]. All data were normalized to the untreated control group (error bars = standard deviation, n = 6).
