Abstract
Larrea tridentata and Ambrosia deltoidea are shown to produce compounds that inhibit replication of HIV. The compounds can be extracted by differential fractionation and by counter-current chromatographic methods described herein. Extracts prepared from L. tridentata and A. deltoidea are found to be effective in inhibiting viral replication. The extracts from L. tridentata have been characterized and found to contain tricyclic lignans. The extracts can be administered to subjects for treatment of viral infection.
