P. Amouroux et al., ANTIVIRAL ACTIVITY IN-VITRO OF CUPRESSUS SEMPERVIRENS ON 2 HUMAN RETROVIRUSES HIV AND HTLV, PTR. Phytotherapy research, 12(5), 1998, pp. 367-368
A proanthocyanidin polymer fraction (MW 1500-2000 daltons) from Cupres
sus sempervirens L. (Cupressaceae) exhibited true antiviral activity i
n vitro against two retroviruses, HIV and HTLV III B. In comparison wi
th AZT no toxicity was observed with PPC at concentrations of 50 mu g/
mL which exceeded the IC50 values (1.5 to 15 mu g/mL for HIV and 5 to
25 mu g/mL for HTLV). (C) 1998 John Wiley & Sons, Ltd.
