Preparation of Luteolin by Microwave Irradiation

Rutin was reduced to luteolin by dithionite with microwave irradiation in aqueous sodium hydroxide solution. Te yield of luteolin was 67% when the mixture was refluxed for twenty minutes under 250 W for three times. The method of preparation of luteolin is convenient and timesaving with high yield. At the same time, the advantage and mechanism of heating have also been discussed.

Abstract:

Rutin was reduced to luteolin by dithionite with microwave irradiation in aqueous sodium hydroxide solution. Te yield of luteolin was 67% when the mixture was refluxed for twenty minutes under 250 W for three times. The method of preparation of luteolin is convenient and timesaving with high yield. At the same time, the advantage and mechanism of heating have also been discussed.
