ABSTRACT
Objective: The aim of the paper was to assess the wound healing potential of three medicinal plants using the excision wound healing model on albino rat. Materials and Methods: Soxhlet extraction method was utilized for the partition of the constituent of interest. Qualitative analysis and phytochemical screening were performed for the detection of tannins, alkaloids, resins, flavonoids, glycosides, steroids, proteins, carbohydrates, and amino acids. Three plants extract used for the ointment formulation and prepared by the addition of extract of Artocarpus heterophyllus,Murraya koenigii, and Punica granatum inpolyethylene glycol ointment base. Three ointment formulations and six extracts with 5% and 10% extract concentration have been used. Excision wound rat model utilized for the wound healing potential. Results and Conclusion: All three plants, including A. heterophyllus Lam.,M. koenigii Linn., and P. granatum Linn.extracted for the active constituent. The pharmacological evaluation on the excision wound healing model suggested that Group-I animals showed 52.09% of healing, whereas povidone-iodine treated animals showed 100.00% healing. On the other hand, the ointment formulation treated F-1 showed 96.47% of wound healing, F-2 showed 97.68% healing, and F-3 showed 99.11% healing. The overall healing results can be represented as following: Control <MKL5 <MKL10 <PGB5 <PGB10 <AHP5 <AHP10 <F-1 <F-2 <F-3 <Standard. F3 ointment formulation is better than the F2 and F1 formulation in wound healing potential as compared to others. Discussion: These studies have indicated that ointment formulations of A. heterophyllus, M. koenigii, P. granatum have been utilized for wound healing potential and it is safer for topical application. Excision wound healing model suggested that the three individual plant extract has shown the wound healing potential, although the prepared ointment formulations F3 have best and synergistic action than the individual. The ointment formulations containing plant extracts in 10% amount have better wound healing potential.
ABSTRACT
Objective: The aim of the paper is to assess the anti-inflammatory potential of three medicinal plants using two rat models. Materials and Methods: Soxhlet extraction approaches utilized to separatethe constituents of interest. Quantitative analysis has been performed to determine the total phenolic and flavonoid content. Three plants extract employed for the ointment formulation by addition of the extract of Artocarpus heterophyllus (AH), Murraya koenigii (MK), and Punica granatum (PG) inpolyethylene glycol (PEG) ointment base, a blend of PEG 600 and PEG 4000, and ratio 7:3, respectively.Two rat models based on chemical induced animals employed for the anti-inflammatory potential. Results and Discussion: All three plants including AH Lam., MK Linn., and PG Linn. extracted for the major component and have shown the gallic acid and quercetin as major component for flavonoid and phenol content. The ointment formulation F3 has showed maximum inhibition (80.95%) at 50 mg/kg dose of carrageenan-induced edema and 83.33% inhibition at 100 mg/kg dose. The ointment formulation F3 has showed maximum inhibition (78.57%) at 50 mg/kg dose of histamine persuade edema and 83.33% inhibition at 100 mg/kg dose. F3 ointment formulation is better than the F2 and F1 formulation in inhibition and in all phases showing its reserve of kinins as well as arachidonic acid. Conclusion: Quantitative and pharmacological evaluation indicated that ointment formulations of AH, MK, and PGhave exploit for anti-inflammatory activity. The normal extract has shown the least activity but ointment formulations have shown the better result. The ointment formulations containing plant extracts in 10% amount have better wound healing potential.
