Quercus salicina is an oak species found in Japan, South Korea and Taiwan. It is placed in subgenus Cerris, section Cyclobalanopsis. [1]

The larvae of the Japanese oakblue ( Arhopala japonica ), of Acrocercops vallata and Marumba sperchius feed on Q. salicina.

Stenophyllanin A, a tannin, [2] and other quinic acid gallates [3] can be found in Q. salicina. The triterpene friedelin can also be isolated from the leaves of the tree. [4]
