Improved Delivery of Caffeic Acid through Liposomal Encapsulation

Table 2

Time dependent changes in the size and zeta potential of caffeic acid loaded liposomes and unloaded liposomes (each value represents the mean ± SD, ).

Systems	Average size/nm			Zeta potential/mV
	0 months	1 month	2 months	0 months	1 month	2 months
Unloaded liposomes	100 ± 27	112 ± 23	110 ± 31	−40 ± 3	−42 ± 5	−44 ± 7
Caffeic acid loaded liposomes	100 ± 35	104 ± 34	108 ± 28	−55 ± 4	−52 ± 6	−49 ± 4
