Abstract:

Young leaves of L.bararum and L.chinense with different geographical origins were compared for differences in main active compounds, such as polysaccharides and total flavonoids. Among geographical populations of each species and between the two species, no significant differences in contents of polysaccharides and total flavonoids were seen, respectively. While the content of polysaccharides in young leaves of L.chinense were significantly higher than that of L.bararum. Hence, L.chinense leaves were a potential source for medicinal food. Science there were significant differences in contents of polysaccharides and total flavonoids within the same geographical population of each species, it is of great interest to develop good varieties by interstrain breeding.

Key words: L.bararum, L.chinense, total flavonoids, polysaccharides, medicinal food
