Abstract

Aqueous extracts of Centella asiatica L. Urban were encapsulated by an edible biopolymer, gelatin, which has no effect on their cosmetic activities. The nanoparticles were w/o-type spherical liposomes that had an average diameter of 115.0nm. The encapsulation efficiency was estimated to be approximately 67%, which was relatively high for these aqueous extracts. The nanoparticles showed lower cytotoxicity (10%) in human skin fibroblast cells than the unencapsulated crude extract (15%) at 1.0mg/ml, this was possibly because a smaller amount of the extract was present in the nanoparticles. The nanoparticles efficiently reduced the expression of matrix metalloproteinase (MMP)-1 in UV-irradiated cells from 136.1% to 77.6% (UV-irradiated control) and inhibited hyaluronidase expression (>60%) at a concentration of 0.5mg/ml, which was higher than the levels produced by the unencapsulated crude extracts. The nanoparticles had a very high flux through mouse skin and also remained at relatively large concentrations in the derma when compared to the unencapsulated crude extracts. These results clearly indicate that the skin-protective activities of C. asiatica were significantly improved through the nano-encapsulation process. These findings also imply that a crude extract can be used and have the same efficacy as purified compounds, which should reduce the purification process and production costs.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Delivery systems such as nanoencapsulation could be used to increase C. asiatica's wound healing properties, extending the areas that can be treated due to higher bioavailability and skin penetration.

    “Delivery systems such as nanoencapsulation could be used to increase C. asiatica’s wound healing properties, extending the areas that can be treated due to its higher bioavailability [46] and penetration through the skin [54].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
