Combretum is the largest and most widespread genus of Combretaceae. The genus comprises approximately 200-250 species distributed throughout the tropical and subtropical regions mainly in Africa and Asia. Combretum has shown its potential as a source of various secondary metabolites. This review focuses on the chemistry of isolated compounds which is about 223 from 20 species as well as biological activity of extracts and phytochemicals of the genus Combretum. This review also focuses on ethnomedicinal practices of Combretum species. The phytochemicals reported from this genus are belonging to the various structural groups such as terpenoids, flavonoids, phenanthrenes and stilbenoids etc. Combretum extracts exhibited in vitro bioactivities such as antibacterial, antifungal, antihyperglycemic, cytotoxicity against various human tumor cell lines, anti-inflammatory, anti-snake, antimalarial and antioxidant effects. In vivo studies through various animal models have also shown promising results. The aim of this book is to boost up chemists, biologists and pharmacologists to undertake further systematic research work on this important genus.

Summary
Shan Frankland forever abandoned the world she knew to come to the rescue of a lost colony on a distant and dangerous planet -- a hostile world coveted by two alien races and fiercely protected by a third. But in the course of her mission, she overstepped a boundary and stumbled into forbidden lands. And she can never go back -- to being neutral, to being safe. To being human.
War is coming again to Cavanagh's Star -- and this time, the instigators will be the troublesome gethes from the faraway planet Earth. Former Environmental Enforcement Officer Shan Frankland has already crossed a line, and now she is a prize to be captured ... or a threat to be eliminated. But saving a coveted world and its fragile native population may require of her one unthinkable sacrifice: the destruction of her own ruthless, invading species.
