                 摘要:为提高辅酶 Q10(CoQ10)的透皮吸收效果,以辛酸/癸酸甘油三酯(GTCC)为液体脂质、鲸蜡醇棕榈
                 酸酯(CP)为固体脂质,制备了不同质量分数固体脂质(以固液脂质的总质量为基准,下同)的 CoQ10-脂质
                 纳米囊,并对其稳定性及透皮性能进行了考察。结果表明,固体脂质的添加未对 CoQ10-脂质纳米囊的粒径及储
                 藏稳定性产生影响,粒径均为 52 nm 左右,储藏 180 d 后其粒径及外观均无明显变化;FTIR 结果表明,CoQ10
                 与脂质纳米囊之间未发生化学反应且能被很好地包埋在脂质纳米囊中;通过闭合效应、体外透皮实验及激光共
                 聚焦的观察发现,当 CP 的质量分数增加至 70%和 95%时,CoQ10-脂质纳米囊能显著减少皮肤水分的蒸发,并
                 更好地促进 CoQ10 透皮吸收,使表皮层和真皮层的荧光强度明显增强。

                 Abstract: In order to improve the transdermal delivery of coenzyme Q10 (CoQ10), CoQ10 nanocapsules
                 with different mass fractions of solid lipids (based on the total mass of solid and liquid lipids, the same
                 below) were prepared using caprylic/caprate triglyceride (GTCC) as liquid lipid and cetyl palmitate (CP) as
                 solid lipid. The stability and transdermal properties of the samples were studied. The results showed that the
                 addition of solid lipids had no effect on the particle size and storage stability of CoQ10 nanocapsules. The
                 particle size of CoQ10 nanocapsules with different mass fractions of solid lipids was about 52 nm. After
                 storage  for  180  days,  there  was  no  significant  change  in  particle  size  and  appearance  of  CoQ10
                 nanocapsules.  FTIR  results  revealed  that  there  was  no  chemical  reaction  between  CoQ10  and  lipid
                 nanocapsules, and CoQ10 could be well encapsulated in nanocapsules. The results of occlusive effects, in
                 vitro transdermal test, and laser confocal microscopy indicated that when the mass fraction of CP increased
                 to  70%  and  95%,  the  prepared  CoQ10  nanocapsules  could  significantly  reduce  the  evaporation  of  skin
                 water,  promote  the  transdermal  absorption  of  CoQ10,  and  enhance  the  fluorescence  intensity  of  the
                 epidermal layer and the dermal layer.
