title: Anti-emetic principles of Poria cocos.
abstract: The triterpenes isolated from P. cocos and their derivatives were examined for anti-emetic activity. Some of these triterpenes inhibited emetic action induced by oral administration of copper sulfate pentahydrate to leopard frog. The triterpenes having an exomethylene group at C-24 showed anti-emetic activity to frogs.
