Abstract
Leaf-press-juices of 53 higher plants were compared on their inactivating power against Tobacco mosaic virus.
No connection was found between the taxonomic group such as family or genus of the plants and the inhibitory power of their juices.
Among the plants known to contain much tannins, followings were found to have powerful inhibitory effects upon TMV infections: Acer insulare, Aesculus turbinata, Aralia elata, Camellia japonica, Distylium racemosum, Geranium nepalense, Lagerstroemia indica, Punica granatum, Robinia pseudoacacia, Sambucus sieboldiana, Thea sinensis.
