Abstract[Objective]To compare the content of water and bioactive component under different drying methods in the extracts of Hippophae rhamnoides.[Method]Using separately hot air drying method, UV, HPLC to determine the content of water, total flavonoids and isorhamL-3-o rutin by different drying methods of vacuum freeze drying, low-temperature oven drying and high-temperature oven drying in the extracts of Hippophae rhamnoides. [Result]The water content was the lowest,the contents of total flavonoids and isorhamnetin-3-O rutin were the highest in freeze-drying method than the other two.[Conclusion]The drying method has a certain effect on the water content and active ingredient content of Hippophae rhamnoides extract. The results of this study provide experimental basis for further research and utilization of Hippophae rhamnoides extract.

沙棘為胡颓子科植物沙棘(Hippophae rhamnoides L.)的干燥成熟果实,蒙古族、藏族习用药材,具有健脾消食、止咳祛痰、活血散瘀的功效,用于治疗脾虚食少、食积腹痛、咳嗽痰多、胸痹心痛、瘀血经闭、跌扑瘀肿等症[1],是国家卫健委公布的药食同源中药。沙棘富含多种化学成分,包括黄酮类、糖类、维生素类、甾醇类、类胡萝卜素类、挥发油类及微量元素等[2-4]。黄酮类化合物为其重要的活性物质,主要包括槲皮素、异鼠李素、杨梅素、山奈酚等黄酮苷元及其苷类,在治疗心脏疾病、高血压、高血脂、高血糖、肿瘤等方面具有良好的作用[5-7]。
中药提取物的干燥过程是其制备过程的重要环节,不同的干燥方法对提取物中指标成分有不同程度的影响[8-9]。笔者以沙棘总黄酮、异鼠李素-3-O芸香糖苷为指标成分,分析不同干燥方法对沙棘提取物中活性成分的影响,为优化沙棘提取物的干燥工艺提供试验依据,也为其进一步开发利用提供参考。……
