Effect of a Gel Based on Ipomoea batatas (Purple Sweet Potato) on Dermal Wound Healing in Mice

Abstract

Background: Ipomoea batatas (L.) Lam. (I. batatas) is a root native from South America that is characterized by its antioxidant, antimicrobial and anti-inflammatory properties. These properties contribute to the wound healing process. Objective: To evaluate the healing activity of a gel based on I. batatas on dermal wound healing in mice. Material and methods: An acid ethanolic extract (1.5 N hydrochloric acid: Ethanol 96 ° 15:85, v / v) was prepared with the peels of the roots of I. batatas "purple sweet potato", which was incorporated into the formulations 0.5% and 1% gel. Mus musculus Balb / c with induced injury were distributed in four experimental groups: Group I (Control), which did not receive any treatment. Group II (Gel base), Group III (Gel I. batatas 0.5%) and Group IV (Gel I. batatas 1%) received the daily administration of topical treatments for 14 days. Wound closure was determined during the experimentation time, then they were euthanized with sodium pentobarbital 60 mg / kg / pc v.ip. to obtain skin samples for histopathological analysis. Results: Group IV shows a higher percentage of wound closure, which is also evidenced in histopathological changes. Conclusions: The 1% gel based on the ethanolic extract of the peels of the roots of Ipomoea batatas (L.) Lam. they show healing activity in wounds induced in mice, being the most effective treatment.

Advances in valorization of sweet potato peels: A comprehensive review on the nutritional compositions, phytochemical profiles, nutraceutical properties, and potential industrial applications

“…A group of scientists made a cut perpendicular to the longitudinal axis of the mouse and subsequently evaluated the would‐healing effect of the gel containing SPP extracts prepared by acidified 96% ethanol (Silva‐Correa et al., 2021). The percentage of wound closure during 14 days was measured.…”

The Effects of Potato (Solanum tuberosum L. vs. Granola; Solanaceae) Peel Extract Gel on Gingival Wound Healing in Wistar Rats

“…A wound is characterized as a disruption in the continuous layer of epithelial tissue in the skin or mucosa, often resulting from thermal or physical trauma. 1 There are four stages in the process of tissue development and regeneration during wound healing: (i) the hemostasis phase, which immediately follows the injury; (ii) the inflammatory phase, marked by swelling and initiated upon tissue damage; (iii) the proliferation phase, in which new tissue and blood vessels form; and (iv) the maturation phase, during which tissue remodeling takes place. 2 Various factors can impede the natural course of wound healing, including factors such as repeated injury, infection, insufficient oxygenation, and the generation of free radicals.…”
