Inhibition of inula cappa (Ham. ex D. Don) DC. extracts on herpes simplex virus infection in vitro
The methanol and dichloromethane extracts of Inula cappa (Ham. ex D. Don) DC. were evaluated for inhibition of herpes simplex virus infection. Higher anti- herpes simplex virus (HSV) activity of I. cappa methanol extract was observed comparing with I. cappa dichloromethane extract since more than 50...
