Evaluation of Skin Repairing and Antifungal Properties of Alcoholic Extract of Laleh abbasi (Mirabilis jalapa) Leaf on Induced Wounds in Laboratory White Rat Model

Based on the historical and recently published documents, it has been demonstrated that Mirabilis jalapa as a herbal medicine may be used as remedies for various health problems included wound healing purposes.

The present study aimed to investigate the effect of ethanolic extract of Laleh abbasi green leaf on healing open wounds induced by skin puncture in the back of rats.

Collecting and drying Laleh abbasi leaves, leaf extracting through Soxhlet procedure, analyzing the extract via gc / ms method, and preparing eucerin-based extract ointment were done according to recommended routine procedures. Herein, we recruited 40 male rats that were randomly divided into five groups of eight, namely the control, phenytoin treatment, eucerin, 5% eucerin extract, and 7.5% eucerin extract ointment treatment groups. Skin puncture and application of ointments on the induced wounds were carried out. Subsequently, tissue samples were taken on days 3, 7, 10, and 14, followed by which histological slides were prepared and stained with H&E and Masson’s trichrome staining methods. In vitro mycological studies were conducted using opportunistic fungi, including Candida, Mucor, and Aspergillus species.

Based on the macroscopic evaluations of the wound healing process and microscopic assessments of tissue samples stained with Harris H&E and Masson’s trichrome methods, the groups treated with eucerin-based ointments containing ethanolic extract of Laleh abbasi leaf had statistically significant positive wound healing responses compared to the other groups. However, the 7.5% ointment group showed statistically better responses compared to the 5% ointment group. The data obtained in the present preliminary experiment on rat model indicated that the extract could facilitate the wound healing process in terms of healing parameters, such as accelerating epithelium repair, creating a favorable inflammatory reaction, angiogenesis, fibroplasia, and collagen precipitation. The antifungal effects of ethanolic extract of Laleh abbasi leaves on Aspergillus fumigatos, fusarium, Candida albicans and Candida cruzei were demonstrated in vitro using saboro dextrose agar medium.

According to the findings of this experimental study and the findings of other researchers, it can be concluded that ethanolic extract from Laleh abbasi leaves is of healing and antifungal properties.
