Rosemary extract health benefits

Spices (rosemary, sage, thyme) contain considerable amounts of flavonols and flavones, mainly in the glycoside form (154). Thus, phenolic analyses in spices were often considered in order to determine the optimum time for plant collection to give maximum flavonoid contents and for health benefits (154,155). Flavonoids (naringin, luteolin, apigenin, and chrysoeriol) were extracted from spices using a percolation process at room temperature with solvents (MeOH and EtOAc), and HPLC analysis was carried out (155). 

This chapter will focus on developments in rice bran oil and sesame seed oil, both of which have exceptional oxidative stability and diverse biological activity. In addition, rosemary antioxidants will be described, with an account of methods for extracting bioactive compounds and a discussion of the stability of these compounds in food systems. Recent literature on the stability and health benefits of flavonoids will complete the chapter. 

A variety of health benefits including cancer prevention, anti-inflammatory, antiviral, and anti-tumor activities have been claimed for carnosic acid, carnosol, and rosmarinic acid. Mirmunni et al. (1992) found that a rosemary extract containing 8.8% carnosic acid and 1.2% carnosol had antimutagenic activity in...
