Abstract
Extracts of 11 samples of seaweeds collected from Egyptian Red Sea shores, represent three major algal groups (Green, Red and Brown) were screened for antibacterial, antifungal, antimalarial, antileishmanial and antiviral activities [1,2]. The results showed that, some of them have antimicrobial and antimalarial activities especially the brown alga
Turbinaria ornate
. The antiviral assay of these algal extracts showed that some species exhibited antiviral activity against New castle disease virus (NDV) which has a lethal effect to chicken embryos. The phytochemical studies on three species have been done and resulted is the isolation and identification of several compounds of different chemical classes like 1 which was isolated from the brown alga
Turbinaria ornate
