Changes in stigmasterol during digestion. (A) stigmasterol released during digestion of conventional and PEGylated liposomes; (B) amount and composition of stigmasterol oxidation products formed during digestion of conventional liposomes; (C) amount and composition of stigmasterol oxidation products formed during digestion of PEGylated liposomes. GD: gastric digestion; ID: intestinal digestion; St: stigmasterol; ME: stigmasterol myristate; OE: stigmasterol oleate; PegL: PEGylated liposomes. Data are expressed as the mean ± standard deviation of three replicates. Different superscript letters in (A) denote statistically significant differences (p < 0.05).
