The aim of the present study was to evaluate the wound healing potential and possible mechanism of action of the standardized extract ofagainst the experimental model of diabetic foot ulcer.-Boswellic acid was isolated from the standardized extract ofand characterized (HPLC,H-NMR,C-NMR, ESI-MS). Diabetes was induced in Sprague-Dawley rats by streptozotocin (55 mg/kg, i. p.), and wounds were created on the dorsal surface of the hind paw.(100, 200, and 400 mg/kg, p. o.) was administered to the rats for 16 days. The HPLC analysis showed a single peak with a retention time of 12.51 min. The compound was identified with ESI-MS [M + Na] = 455.37 as-boswellic acid. Treatment with(200 and 400 mg/kg) significantly increased the rate of wound contraction via modulation of oxido-nitrosative stress and elevated the hydroxyproline level at the wound area. reverse transcription-PCR analysis revealed that streptozotocin-induced increases in TNF-, interleukin-1, interleukin-6, nuclear factor-kappa-light-chain-enhancer of activated B cells, and Bcl-2-associated X protein, and decreases in angiopoietin-1, Tie2, transforming growth factor beta 1, vascular endothelial growth factor, and collagen-1 mRNA expression were significantly inhibited by. It also significantly reduced wound cellular necrosis as evaluated by flow cytometry using propidium iodide fluorescence intensity. Streptozotocin-induced histopathological alterations were also significantly ameliorated by. In conclusion, standardized extracts ofexert its wound healing potential via orchestrating mechanisms, which include the inhibition of oxido-inflammatory markers (oxido-nitrosative stress, TNF-, interleukins, and nuclear factor-kappa-light-chain-enhancer of activated B cells), increased collagen synthesis (hydroxyproline and collagen-1) and angiogenesis (Ang-1/Tie2), promoting growth factors (transforming growth factor beta 1 and vascular endothelial growth factor), and inhibition of apoptosis (Bcl-2-associated X protein) to accelerate wound healing in experimental delayed diabetic foot ulcer.
