Abstract: | Betula platyphylla was one of the important biomaterial resources.Microwaves-assisted extraction of tannins from bark of Betula platyphylla were optimized using uniform design.The optimal conditions were 33% alcohol(v/v)as the extraction solvent,92 s as the extraction time,80 ℃ as the extraction temperature,75 W of microwave power.Tannin yield could reach up to 5.61% with the purity of 51.18% under above conditions. |
