Novel xanthone derivatives, method of production thereof, and pharmaceutical composition containing the same

摘要

Biologically active xanthone derivatives, as well as compositions prepared from such derivatives, possessing anti-cancer activity, anti-inflammatory activity, anti-obesity activity, and/or hair growth promotion activity, and a method for producing such derivatives and compositions. The derivatives are obtained by utilizing a heating, extracting and condensing system that efficiently recovers the derivatives from a raw material.
