近年来，天然多糖因其在医药、美容和食品领域的价值越来越受到关注和研究。丹参是一种传统的中药材，已经使用了数千年，具有抗糖尿病、抗纤维化、神经保护、抗氧化、抗炎等效果。它主要包括远志酸、丹参酮I、丹参酮IIA、丹参酮IIB、原儿茶醛、多糖和丹酚酸。 丹参多糖是从丹参中提取和分离出来的一种多糖，具有抗氧化、抗肿瘤、肝保护、抗炎、免疫调节和心脏保护等多种生物学功能。本文总结了SMPs的提取、纯化、结构表征和生物活性，并提出了SMPs未来研究的新视角。我们希望我们的研究可以为SMPs的进一步研究提供参考。 版权所有©2023 Luo、Xue、Shao、Zhou、Tang、Liu、Hu和Yang。

In recent years, natural polysaccharides have attracted more and more attention and research because of their value in the medicine, beauty and food fields. Salvia miltiorrhiza is a traditional Chinese herb that has been used for thousands of years and has antidiabetic, antifibrotic, neuroprotective, antioxidation, anti-inflammatory and other effects. It mainly includes rosmarinic acid, tanshinone I, tanshinone IIA, tanshinone IIB, procatechualdehyde, polysaccharide and salvianolic acids. Salvia miltiorrhiza polysaccharide is a polysaccharide extracted and isolated from Salvia miltiorrhiza and has diverse biological functions, including antioxidation, anti-tumor, hepatoprotective, anti-inflammatory, immune regulatory and cardioprotective effect. In this review, the extraction, purification, structural characterization and biological activity of SMPs are summarized and new perspectives for the future work of SMPs were also proposed, we hope our research can provide a reference for further research on SMPs.Copyright © 2023 Luo, Xue, Shao, Zhou, Tang, Liu, Hu and Yang.
