Wild Allium victorialis L. in Changbai mountain was collected as raw materials to study its content variation of functional components in bulbs and leaves with different picking time

and find out the best lipid-decreasing time of Allium victorialis L. boiling liquid. Ultrasonic assisted extraction of flavones

saponins and polysaccharides in Allium victorialis L. and measured contents of the three substances individually

the bulbs and leaves boiling liquid in different picking time was taken and used for the experimental mice induced by high-fat diet. In late July

the bulbs and leaves boiling liquid has obviously decreased the content of triglyceride

total cholesterol and low density lipoprotein cholesterin. However

the liquid has obviously rise the high-density lipoprotein cholesterol. And in bulbs of this picking time: the content of flavones is 4.85 mg/g

the content of saponins is 9.54 mg/g

the content of polysaccharides is 56.91 mg/g. In leaves of this picking time: the content of flavones is 9.77 mg/g

the content of saponins is 10.94 mg/g

the content of polysaccharides is 34.24 mg/g. Wild Allium victorialis L. has a good effect of lipid-decreasing.
