Oligosaccharides are a class of bioactive components abundantly found in Chinese herbal medicine. They have clinical effects such as antidepressant and anti-Alzheimer’s disease activities, as well as pharmacological activities such as hypoglycemic, laxative, and immune-enhancing effects. The bioactivity of oligosaccharides is closely related to their structure. However, due to the diversity of glycosidic bond configurations, monosaccharide compositions and linkage patterns, it is difficult to accurately determine their structures by conventional analytical methods. Establishing rapid and reliable analytical methods remains a key challenge in carbohydrate research.Although studies on oligosaccharides are increasing, there is a lack of comprehensive reviews on the structure and analytical methods of oligosaccharides in Chinese herbal medicine. This paper systematically reviewed the research progress over the past decade on extraction, separation, structure identification and analytical methods of oligosaccharides in Chinese herbal medicine by consulting domestic and foreign literatures. This review aims to contribute to the development of evaluation method of traditional Chinese medicine based on oligosaccharide components, and provide reference for their application in the quality control of traditional Chinese medicine.
