Abstract

SOLER ROGER, Dulce María et al. Accelerated stability of a Rhizophora mangle L. (red mangrove) gel for wounds and burns. Rev Cubana Farm [online]. 2011, vol.45, n.4, pp.563-574. ISSN 0034-7515.

The objective of the present paper was to evaluate the accelerated stability of a Rhizophora mangle L. (red mangrove) gel under 2 storage conditions. The three pilot batches (GM01, GM02 and GM03) were stored at two temperature settings: 40 ± 2 °C for three months and 25 ± 2 °C for 6 months. One physical-chemical and microbiological evaluation was performed in two periods of time: at the months 0, 1, 2 and 3 for the first and at the months 0, 1, 2, 3 y 6 for the second tested storage condition. All the batches stored at both temperatures showed stable organoleptic characteristics and extensibility, the pH ranged from 6 to 7 and rheology confirmed a non-Newtonian fluid of Herschel Bulkley-type in the evaluated periods of time. The minimum inhibitory concentration remained 8 to 10 mg/mL whereas the tannin concentration ranged 13 to 30 mg/g. All the batches were within the allowable microbial limits. The red mangrove gel showed good stability under accelerated temperatures, but this is an aspect that requires to be confirmed in a future on-shelf stability study.
