摘要： 利用均匀设计法优化了微波辅助提取白桦树皮中桦木醇的工艺.考察了提取温度、微波功率、提取时间对桦木醇收率的影响,并用高效液相色谱法测定了萃取物中桦木醇的含量.试验结果表明,1 g白桦树皮粉末,在提取温度72℃、微波功率67 W,提取时间100 s的条件下,微波辅助提取的桦木醇收率达到25.43%,纯度达到59.19%.与传统回流提取法相比,微波辅助提取法不仅提取时间短,且提取率高、选择性好,故具有一定的应用前景.

Abstract: The microwave-assisted extraction (MAE) of betulin from Betula platyphylla Suk. bark was optimized using uniform design. The effects of extraction temperature, microwave power, extraction time on betulin yield by MAE were discussed and the betulin content was determined by HPLC. The results showed a betulin yield of 25.43%, a purity of 59.19% was achieved from 1 g powder of B.platyphylla bark under the extraction temperature of 72℃, microwave power 67 W, and extraction time 100 s. Comparing with the traditional reflux extraction, much shorter extraction time and better selectivity were displayed under MAE which might mean a utilizing perspective in some degree.

Key words: betulin, uniform design, microwave-assisted extraction
