Lithocarpus glaber, the Japanese oak, is a tree species in the family Fagaceae found in Japan, China, and Taiwan.
Mitami Shrine, a Shinto shrine in Sakai, Osaka Prefecture, Japan, is famous locally for its comparatively large population of Lithocarpus glaber, known as Shiribukagashi (尻深樫 ã·ãªãÂÂã«ã‹·). In China, it is called ke (æ¯). In Cantonese, it is called Seklik (ç³æ«Â).
Condensed tannins from L. glaber leaves have been analysed through acid-catalyzed degradation in the presence of cysteamine and have a potent free radical scavenging activity.
