Polysaccharide that has been extracted with 1% sodium carbonate from Rooibos leaves (Aspalathus linearis) showed strong anti-HIV activity. Du-Zhong leaves also showed anti-HIV activity, although lower than the extract of Aspalathus linearis, but Japanese tea leaves and a hot water extract of Aspalathus linearis did not. The anti-HIV activity of the alkaline extract from Aspalathus linearis was recovered mainly in the 25-75% ethanol-precipitated fraction. The polysaccharide almost completely inhibited the binding of HIV-1 to MT-4 cells. It is inferred from these results that the polysaccharide from Aspalathus linearis is involved in the mechanism for virus binding to T cells.
