黄精为我国常用传统中药，在长江以南大部分地区广泛分布，具有补益肝肾、延年益寿等作用，是自古以来的道家养生圣药。因其含有多糖、皂苷、黄酮、木脂素、氨基酸、醌类化合物、维生素、生物碱及多种微量元素等成分，从而具有较高的药用价值和营养价值，国内各研究机构对其进行了较深入的研究，国外对其仍处于初步研究阶段。目前实验研究主要集中在黄精多糖、黄精醇、黄精皂苷提取物或黄精水提物上，以动物实验或单方和复方制剂的临床研究为主。其多种黄精制剂已广泛应用于临床，如黄精口服液、黄精茶、苁蓉精颗粒、黄精赞育胶囊、黄精精油眼罩等，发挥着不同的效用。查阅有关黄精的研究文献，对其药理作用进行全面的综合分析，多角度总结其效用价值，为黄精的深入开发与应用提供参考。

As a traditional Chinese herbal medicine, Polygonati Rhizoma widely distributed in most areas south of the Yangtze River. It has the function of nourishing liver and kidney, prolonging life and so on. Importantly, it is a Taoist Holy medicine since ancient times. Polygonati Rhizoma has high medicinal value and nutritional value because it contains polysaccharides, saponins, flavonoids, lignin, amino acids, quinones, vitamins, alkaloids and a variety of trace elements and so on. The domestic research institutions have carried out a deeper exploration, while its research is still at an early stage for foreign countries. At present, the experimental studies are mainly concentrated on the polysaccharides, ethanol, the extracts of saponins or the aqueous extracts of Polygonati Rhizoma. The experimental type is mainly based on the animal experiments and the clinical researches of Polygonati Rhizoma or its compound preparations. Various Polygonati Rhizoma preparations have been widely used in clinic, such as Polygonati Rhizoma Oral Liquid, Polygonati Rhizoma Tea, Cistanche and Polygonati Rhizoma Granules, Polygonati Rhizoma Zanyu Capsules, Polygonati Rhizoma essence oil patch and so on, which play different roles in individual products. In this paper, a comprehensive analysis was carried out on the basis of the latest experimental research on Polygonati Rhizoma, and its utility value was summed up from various angles, which provides a reference for the deep development and application of the Polygonati Rhizoma.
