Batsch leaves to treat skin diseases such as ringworm, scabies, boils... urination, treatment of hydrocephalus and urinary catheterization...Results of quantitative analysis of some components of ethanol extract (LĐ-ET) from Prunus persica (L.) Batsch leaves, including: moisture content (7,1%), total ash content (8.5%), reducing free sugars content (11,8%), cellulose content (12.6%), sterols content (24,3%), flavonoids content (7,5%) and terpenoids content (12,8%) and tannin (11,7%). The ethanol and ethyl acetate extracts of peach leaves have good antifungal and anti-inflammatory activities, inhibition of  NO production with IC₅₀ value of 89,31 g/mL; 69,72 µg/mL. From these results, it is shown that peach leaf ethyl acetate extract has better antifungal and anti-inflammatory activity than ethanol extract, peach leaf ethyl acetate extract has the potential to be developed into a product to support human health care.
