Identification of Major Active Ingredients Responsible for Burn Wound Healing of Centella asiatica Herbs

Centella asiatica herbs have been prescribed as a traditional medicine for wound healing in China and Southeast Asia for a long time. They contain many kinds of triterpenoid compounds, mainly including glycosides (asiaticoside and madecassoside) and corresponding aglycones (asiatic acid and madecass...
