摘要:

以梅花鹿鹿胎盘作为原料,制备具有生物活性的小分子活性物质——鹿胎免疫调节因子。通过正交试验优化超声功率、固液比、超声时间和丙酮量等因素,获得最优化鹿胎提取液制备工艺为超声功率400W、固液比1:2、超声时间120s、(提取液:丙酮比1:3),此条件下鹿胎提取液多肽质量浓度可达30.35mg/mL。之后,利用超滤法处理鹿胎提取液,可得到微黄色透明液体即为鹿胎免疫调节因子,主要含多肽(3.7±0.04)mg/mL、核酸(3.3±0.07)μg/mL、多糖(0.54±0.002)mg/mL,且超滤法显著优于透析法。

Abstract:

Immunoregulatory factors as bioactive small molecules were prepared from sika deer placenta homogenate using ultrasonic-assisted acetone extraction. Process conditions such as ultrasonic power, homogenate-to-normal saline ratio, utrasonic treatment time and homogenate-to-acetone ratio were optimized using an orthogonal array design to be 400 W, 1:1 (g/mL), 120 min and 1:3 (V/V), respectively. The polypeptide concentration of the extract obtained under these conditions was 30.35 mg/mL. The extract was further ultrafiltrated and a clear yellowish liquid containing immunoregulatory factors was obtained. The liquid contained mainly (3.7 ± 0.04) mg/mL peptides, (3.3 ± 0.07) μg/mL nucleic acid and (0.54 ± 0.002) mg/mL polysaccharides, whereas smaller amounts of polypeptides, nucleic acid and polysaccharides were found in the retentate of the extract after dialysis.

Key words: sika deer placenta, immunoregulatory factors, orthogonal array design, preparation process
