Resumen o descripción

The purpose of this work is to develop a mucoadhesive film that serves as a carrier for Lippia

graveolens essential oil (LGO) emulsion and to evaluate in vitro their inhibitory effect against

opportunistic pathogen Candida. albicans. For this, different ratio Chitosan: Pectin (100:0,

75:25, 50:50, 25:75, 0:100) films were obtained by casting technique with different

concentration of glycerol as a plasticizer (0, 10 and 30%). Water-uptake, erosion, and

mucoadhesion were evaluated.

Films with CH:P ratio of 100:0 with 30% glycerol, 75:25 with 10% glycerol and 50:50 with

10% glycerol showed better mucoadhesion and physical properties. Characterization of LGO

was carried out, and major components thymol and carvacrol were quantified by GC-MS, these

phenols were present in a 2:1 ratio. Three different emulsions with LGO were developed and

characterized, their inhibitory effect was evaluated against C. albicans. Arabic gum (GA),

Hydroxylated lecithin (LecH) and polysorbate 80 (T80) were used as emulsifiers. The particle

size of emulsions was 1597±11.1, 179±5.5 and 137.3±4.2 respectively.

All emulsions had an inhibitory effect against C. albicans. Volumes of emulsions that inhibit

the 99% of C. albicans were used for the in vitro test of films together with emulsion.

With this work it was possible to develop three different emulsions with an inhibitory effect

against C. albicans, likewise, these emulsions showed an inhibitory effect in a localized way

when evaluated together with the mucoadhesive films against C. albicans
