Novel Treatment

Natural products derived from plants have been used for decades in traditional medicine. Many classes of compounds exist in plants such as saponins, alkaloids, anti-oxidants, etc. Pentacyclic triterpenes are also one of the compounds occurring in plants. In this class Ursolic acid is a well-recognized compound that is available from various sources like seeds as well as fruits and possess many types of activities and is a bright contender for developing novel treatment approaches for treating diseases.
