中文摘要:

      砂仁是姜科草本植物, 其中品质最佳的当属阳春砂仁。作为药食同源的植物, 砂仁主治脾胃气滞、宿食不消、腹痛痞胀、噎膈呕吐、寒泻冷痢。砂仁具有多糖、挥发性油和黄酮类等多种成分, 其中多糖是砂仁中重要的活性物质, 现代研究证明, 多糖具有提高机体免疫力、调节淋巴细胞等功效, 已经成为食品、医药及生物等领域的研究热点。砂仁多糖的提取方法与其提取率和生物活性密切相关, 为了明确不同提取方法对砂仁多糖提取率的影响, 本文对溶液提取法、超声波辅助提取法和微波提取法3种主要的砂仁多糖的提取方法及其生物活性进行综述, 为后续砂仁多糖进一步研究提供参考和借鉴, 以便于药食两用的砂仁多糖在日常生活中的广泛应用。

英文摘要:

      Amomum villosum Lour. is a herb of the ginger family. Among them, the best quality is Yangchun Amomum villosum Lour. As a plant having the concomitant function of medicine and foodstuff, Amomum villosum Lour. is mainly used to treat spleen-stomach stagnation, indigestion, bellyache and fullness or distension, dysphagia and vomit, cold diarrhea and cold dysentery. There are multiple ingredients in Amomum villosum Lour., such as polysaccharide, volatile oil, flavonoids, etc. Among them, polysaccharide is an important active substance in Amomum villosum Lour.. Modern research proves that polysaccharides have the efficacy of improving immunity and regulating lymphocytes, and have become a hot spot for research in the fields of food, medicine and biology. The extraction method of Amomum villosum Lour. polysaccharide is closely related to its extraction rate and biological activity. In order to define the effect of different extraction methods on the extraction rate of Amomum villosum Lour. polysaccharide, this paper reviewed the 3 kinds of main extraction methods and their bioactivities of Amomum villosum Lour.. polysaccharides by solution extraction, ultrasonic-assisted extraction and microwave extraction, in order to provide a reference for further research on Amomum villosum Lour. polysaccharides and to facilitate the wide application of Amomum villosum Lour. polysaccharides for medicinal and food purposes in daily life.
