Dandelion root polysaccharide (DRP), a key bioactive component of Taraxacum officinale, has anti-inflammatory, antioxidant, hypoglycemic and hypolipidemic activities. This study extracted DRP via microwave-assisted enzymatic extraction (MAEE) to obtain mDRP, and isolated acidic polysaccharide mDRP-1 (7.548 kDa) by column chromatography. HPLC showed that both contain six monosaccharides (Man, Rha, GalA, Glu, Gal, Ara) with different molar ratios. mDRP is heterogeneous (trace protein\/nucleic acids, no triple helix, amorphous), while mDRP-1 has a triple-helical, semi-crystalline structure; both have characteristic polysaccharide peaks and pyranose rings, and rough, porous surfaces. mDRP had better thermal stability and significant concentration-dependent in vitro antioxidant and hypoglycaemic effects.<\/jats:p>","DOI":"10.3390\/molecules31172966","type":"journal-article","created":{"date-parts":[[2026,8,25]],"date-time":"2026-08-25T10:04:55Z","timestamp":1787652295000},"page":"2966","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Comparative Structural Characterisation and In Vitro Bioactivities of Crude and Purified Polysaccharides from Dandelion (Taraxacum officinale) Root Using Microwave-Assisted Enzymatic Extraction"],"prefix":"10.3390","volume":"31","author":[{"given":"Jingwen","family":"Zhang","sequence":"first","affiliation":[{"name":"College of Food and Bioengineering, Qiqihar University, Qiqihar 161006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fujuan","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Biochemical Engineering, Chaoyang Normal University, Chaoyang 122000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuxuan","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Food and Bioengineering, Qiqihar University, Qiqihar 161006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cuntang","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Food and Bioengineering, Qiqihar University, Qiqihar 161006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guojun","family":"Du","sequence":"additional","affiliation":[{"name":"College of Food and Bioengineering, Qiqihar University, Qiqihar 161006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"846","DOI":"10.1016\/j.ijbiomac.2018.12.232","article-title":"Ultrasonic-assisted enzymatic extraction and characterization of polysaccharides from dandelion (Taraxacum officinale) leaves","volume":"126","author":"Wang","year":"2019","journal-title":"Int.
