“…Se demostró que las antocianinas tienen actividad antibacteriana debido a que alteran la pared celular bacteriana, los flavonoides provocan la inhibición de la síntesis de ácidos nucleicos, la inhibición de la biopelícula, inhibición de ADN girasa y la inhibición de la función de la membrana. Se descubrió también que el ácido de hibisco inhibe el crecimiento bacteriano, alterando la permeabilidad de la membrana (51).…”

La caries dental es una de las enfermedades más frecuentes a nivel mundial y debido a su prevalecía se comenzó a utilizar la fitoterapia como tratamiento alternativo, la Hibiscus sabdariffa L. posee gran variedad de propiedades terapéuticas de las cuales en este estudio destaca su actividad antibacterial. Objetivo: El objetivo de esta investigación fue determinar el efecto antibacterial in vitro del extracto etanólico de Hibiscus sabdariffa L. sobre cepas de Streptococcus mutans a las 24 y 48 horas. Materiales y métodos: La investigación fue aplicativa de diseño experimental y medición prospectiva. La muestra fue obtenida de pacientes que firmaron el consentimiento informado para así poder obtener las cepas de Streptococcus mutans. Se cultivaron en 16 placas Petri y en cada placa se distribuyeron 7 discos de papel filtro N°4, la técnica fue de difusión por disco de Kirby Bauer con pozos, con un total de 112 discos y pozos; las placas Petri se dividieron en 4 grupos de acuerdo a las concentraciones del extracto etanólico de Hibiscus sabdariffa L. que se obtuvo por maceración con alcohol al 96% para obtener una muestra al 100% extracto etanólico de Hibiscus sabdariffa L. y para obtener las concentraciones de 25%, 50% y 75% se utilizó alcohol para realizar las diluciones. Se consideró la clorhexidina al 0.12% como control positivo y al agua destilada como control negativo. Resultados: Sé demostró que la Hibiscus sabdariffa L. tiene efecto inhibitorio. El mejor efecto se registró a las 48 horas al 100% de concentración. Obteniendo un halo de inhibición de 14.23mm. Conclusión: El extracto etanólico de la Hibiscus sabdariffa L. sí tiene efecto antibacterial in vitro sobre las cepas de Streptococcus mutans.

Dental caries is a problem in the human oral cavity due to the buildup of plaque, which is caused by bacteria such as Streptococcus mutans. Nevertheless, mouthwash may result in a parched mouth and numbness in the oral cavity. Antibacterial properties are therefore recognized in the rosella flower plant (Hibiscus sabdariffa L.). This research was conducted to ascertain the antibacterial activity of the combination of Ethanol Extract of Rosella Flowers (EER) and chlorhexidine gluconate (CHG) 0.2% in inhibiting the growth of S. mutans ATCC 25175 bacteria. The maceration method was employed in the extraction procedure, and the agar well diffusion method was followed for antibacterial testing. The concentrations of EER were 5%, 10%, and 20%. The combination of EER 5% and CHG 0.2% was made in comparison series of (1) 1:3, (2) 1:1, and (3) 3:1. Furthermore, the diameter of the inhibitory zone (DZI) and the calculation of Combination Index (CI) were analyzed. The EER at 5%, 10%, and 20% revealed DZI of 12.17 ± 1.04, 21 ± 0.87, and 32.17 ± 0.29 mm, respectively. Then, the combination series of EER 5% and CHG 0.2% of (1) 1:3, (2) 1:1, and (3) 3:1 uncovered DZI of 32.17 ± 0.58; 31.67 ± 1.89; 27.67 ± 0.76 mm, respectively, categorized as very strong. The CI showcased that a combination was antagonistic. The chemical compounds of EER 5% increased the DZI towards S. mutans ATCC 25175 in combination with CHG 0.2%.

Roselle (Hibiscus sabdariffa) is a Malvaceae with multiple economic and pharmacological potential, little or poorly known and under-exploited in Cameroon. The aim of this study was to assess the genetic variability of 36 collections from several countries in the Central African sub-region, in an alpha lattice design (6x6) with two replications at the University of Yaoundé I. The data collected from five plants in each plot per replication were randomly selected from the middle row, excluding the border plants, and harvested at the stage of 50% flowering. Principal Component Analysis (PCA) and Hierarchical Clustering Analysis (HCA) were estimated using the R software variability package (version 3.5.1). The analysis of variance results from the 20 traits evaluated including 13 qualitative and 7 quantitative showed significant differences (P < 0.0001) between accessions at 60 days after sowing. Average heights to first branch ranged from 2.62 to 14.70 cm and the plant heights ranged from 10.5 to 86 cm. Mean collar diameter values varied between 0.40 and 1.36 cm. Collar diameter was strongly and positively correlated with the number of branches (r = 0.8) and with the 50% flowering date. Flower bud initiation date (DIBF) was negatively correlated with chlorophyll index (-0.6) and plant height (-0.4). Hierarchical clustering grouped the collections into 03 groups of 10 collections, 12 collections and 14 collections respectively. However, no differences were observed between collection origins for all parameters studied. High heritability was recorded for growth parameters such as collar diameter (0.6143), number of branches (0.6363), plant height (0.7240) and height of first branch (0.7653), revealing strong potential for selection and genetic improvement. The first two axes of the PCA which explained 64.7% were taken into account. The association of quantitative variables and collections showed the top 10 collections which represented potential parents for breeding programs.
