Title: Appled Study on Extration of Total Flavonids from Bamboo Leaves
Abstract: Microwave extraction was used to extract total flavonoids from bamboo leaves and the influence of ethanol concentration,material solvents,extracting time and microwave power on the extractive yield were investigated.From orthogonal test the appropriate extracting parameters were determined as follows: ethanol concentration 70 %,microwave power 150 W,time 150 s,material solvents 1∶20(g/mL).The extraction of flavonoids from Pleioblastus amarus,Phyllostachys violascens,Indocalamus latifolius,Ph.nigra and Ph.edulis leaves were 10.858,13.835,5.141,18.778,15.552 mg/g under these conditions,which is similar to other optimum extraction methods.It indicates that the extracting parameters is suitable for the most bamboo and microwave extraction is simple,convenient,highly efficient and environmental.
