Advancements in the extraction, characterization and function activities of polysaccharides from Physalis L.: A review

Physalis L. primarily including five species (P. alkekengi, P. minima, P. angulate, P. pubescens, P. peruviana), with a long history of medicinal and edible use in Asia. The fruit of such plants are not only juicy and appealingly sweet and sour but also an excellent source of vitamin C and dietary fiber, making it popular choice in Northeast China. Polysaccharides are among the key active ingredients in Physalis L. plants and have attracted significant attention from researchers due to their diverse biological properties, including anti-inflammatory, antioxidant, immunomodulatory, antibacterial, hypoglycemic, and prebiotic activities. Numerous polysaccharides have been successfully extracted from Physalis L. plants over the past few decades, highlighting their potential in health and nutrition. Despite these advances, there remains a significant lack in the comprehensive evaluation of the extraction processes, intricate high-level structures, and structure-activity relationships pertaining to Physalis L. polysaccharides (PLPs). Given the significance of PLPs in the food industry, biological studies, and drug discovery, a systematic review of PLPs is imperative. This review aims to consolidate existing knowledge regarding their extraction, purification, structural characteristics, functional activities, and potential applications. This provides valuable insights for the application of PLPs in fields such as medicine, functional foods, and cosmetics.

Genus Physalis L.: A review of resources and cultivation, chemical composition, pharmacological effects and applications

ETHNOPHARMACOLOGICAL RELEVANCE

The genus Physalis L. (Solanaceae) is commonly used in the treatment of dermatitis, leprosy, bronchitis, pneumonia, hepatitis and rheumatism in China and other Asian countries.

AIM OF THE REVIEW

This article reviews the resources, cultivation, phytochemistry, pharmacological properties, and applications of Physalis L., and proposes further research strategies to enhance its therapeutic potential in treating various human diseases.

MATERIALS AND METHODS

We conducted a systematic search of electronic databases, including CNKI, SciFinder and PubMed, using the term "Physalis L." to collect information on the resources, phytochemistry, pharmacological activities, and applications of Physalis L. in China during the past ten years (2013.1-2023.1).

RESULTS

So far, a variety of chemical constituents have been isolated and identified from Physalis L. mainly including steroids, flavonoids, and so on. Various pharmacological activities were evaluated by studying different extracts of Physalis L., these activities include anti-inflammatory, antibacterial, antioxidant, antiviral, antineoplastic, and other aspects.

CONCLUSION

Physalis L. occupies an important position in the traditional medical system. It is cost-effective and is a significant plant with therapeutic applications in modern medicine. However, further in-depth studies are needed to determine the medical use of this plant resources and cultivation, chemical composition, pharmacological effects and applications.
