番石榴多糖化学与生物活性研究进展

Research Progress on Chemical and Biological Activity of Psidium guajava Polysaccharides

番石榴(Psidium guajava)为桃金娘科植物,在全球热带及亚热带地区广泛种植。番石榴具有良好的食用和药用价值,长期被用于腹泻、糖尿病等疾病的辅助治疗。多糖是番石榴中的重要活性成分,具有抗氧化、抗肿瘤、抗炎、调节免疫、降血糖、改善肠道微生态等作用。该文对已报道的番石榴多糖提取方法、结构表征及生物活性相关研究进行梳理与总结,以期为番石榴及其多糖类成分在食品及医药领域的进一步开发利用提供参考和借鉴。

Psidium guajava,a type of fruit tree belonging to the Myrtaceae Family,is widely grown in tropical and subtropical area in the world.In addition to its good edible value,P.guajava is valued for its nutritional and medicinal properties and has been traditionally used as a supportive treatment for multiple diseases such as diarrhea and diabetes.Polysaccharides are major bioactive constituents of P.guajava and have antioxidant,anti-tumor,anti-inflammatory,immunoregulatory,hypoglycemic,and improving gut microbial dysbiosis effects.This review summarizes reported extraction method,structural characterization and biological activities of polysaccharides from P.guajava are reviewed and summarized.The aim is to provide a reference for the further development and utilization of P.guajava and its polysaccharides in food and pharmaceutical industry.
