Evaluation of wound healing potential of Jatropha curcas leaf extracts ointment based on wound infection in Wistar rats model

Abstract

This research study was conducted to evaluate the wound healing potential of ointment formulated with Jatropha curcas leaf extracts based on wistrar rat model. The therapeutic activities of the plant extracts were determined by topical application of the herbal ointment. Wound healing rate took place on the 16th day of post treatment with 1.0 g of J. curcas ointment formulation and 12th day with 2.0 g of the ointment, was similar compared with standard drug Gentamicin ointment (12 days). The control untreated group (62.3±0.51%) rate of wound closure observed persisted beyond the 19th day of post-wounding. The haematological parameters of the infected rats treated with herbal ointment and the control group untreated were not significant different (p>0.05). Significant increase in white blood cell (WBC) count in untreated group was recorded when compared with the treated group. However, treatment with the formulated ointments significantly increase the elevated WBC count in the treated group. The toxicological parameters in the serum of the rats are useful makers for the assessment of tissue damage. The serum Aspartate Transaminase (AST) and Alanine Transaminase (ALT) activities in the treated and untreated experimental groups were not significantly (p>0.05) different. The phytochemical components found in J. curcas leaves contain some useful potential antimicrobial agents that possess wound healing properties when formulated into a topical ointment for topical application.
