原苏联沙棘油提取工艺介绍及其对我们的启迪

通过分析并对比原苏联获专利的沙棘油提取工艺,探讨了我国沙棘油提取工艺应借鉴的经验。     

沙棘黄酮的制备技术和工艺

介绍了从沙棘果肉中提取和精制沙棘黄酮的技术和工艺。合理设计、借助溶剂纯化脱脂去杂的工艺，以及真空喷雾干燥的使用，不仅可降低生产的运行费用，同时保证了所生产沙棘黄酮具有较高的品质，该设备同样也可用于沙棘叶中黄酮的制取。     

沙棘油产品及提取加工技术

沙棘又称柳酯、黑刺，藏文名为达日布。沙棘属落叶灌木或亚乔木。沙棘具有极强的耐寒、耐旱、耐盐碱和耐土壤贫瘠的生存能力，是建造防风固沙林的重要树种。     

Ultrasound-associated extraction of seed oil of Korean pine

Experiment on ultrasound- associated extraction of seed oil of Korean pine (Pinus koraiensis) was conducted in Northeast Forestry University, Harbin, China. The factors affecting extraction yield, such as ultrasonic frequency, extracting temperature, extracting time and the ratio of material to liquid (ratio of Korean pine seed to absolute alcohol), were analyzed under specific condition and the optimal extracting parameters were obtained as the ultrasonic frequency 32 000 Hz, the extracting temperature 80℃, the extracting time 50 rain, and the ratio of material to liquid 1: 30. The study demonstrates that ultrasound is a reliable and great efficiency tool for the fast extraction of Korean pine seed oil。
