Abstract: The extraction technology of the bioflavonoids in lotus leaf and it’s hydroxyl radicals scavenging capacity werestudied. The results showed that the highest extraction rate of bioflavonoids with high scavenging capacity of hydroxyl radicalscould be obtained with 60% alcohol immersed at the ratio of one part of dry leaf to thirty parts of solvent with microwaveirradiated for 1.5min, extracting time for 2.5h.

Key words: louts leaf, flavonoids, extraction, microwave, hydroxyl radicals
