Author(s): Chandana Choudhury Barua, Shameem Ara Begum, Dilip Kumar Sarma, Debesh Chandra Pathak, Rumi Saikia Borah

The methanol extract of Alternanthera brasiliana Kuntze (Family: Amaranthaceae) leaf was investigated for its wound healing effect by excision wound model (in vivo) in aged Sprague Dawley rats. In excision wound model, compared to the control group, percent contraction of wound was significantly (P < 0.01) higher in A. brasiliana treated group (5% w/w ointment). The collagen, elastin, and hydroxyproline contents of the granulation tissue of A. brasiliana-treated group increased significantly (P < 0.01) compared to the control group, indicating better wound healing activity of the test plant. These findings were also confirmed by histopathological examination. The results suggested that methanol extract of A. brasiliana possesses significant wound healing potential in aged animal wound model.
