Stems are more than structural conduits in plants—they are vital transport hubs and metabolic centers, housing a rich diversity of bioactive polysaccharides. Extracted from various stem tissues, these stem-derived polysaccharides have attracted increasing attention for their antioxidant, anti-inflammatory, immunomodulatory, and anti-tumor properties. Their versatile biological activities make them valuable in pharmaceuticals, nutraceuticals, and cosmeceutical development.
Unlike root polysaccharides, which are more extensively studied, stem polysaccharides represent a rapidly emerging field, gaining interest due to their unique structural diversity, glycosyl composition, and synergistic biofunctions.
Featured Stem Polysaccharides of Interest
Alfa Chemistry offers a diverse portfolio of stem-derived polysaccharides, sourced from time-honored medicinal plants and emerging bioactive species. The following have drawn particular scientific interest for their promising health benefits and functional properties:
🔸 Dendrobium Nobile Polysaccharide
Extracted from the succulent stems of Dendrobium nobile, this polysaccharide is rich in mannose and glucose units. It exhibits immunoregulatory, anti-aging, anti-diabetic, and gut microbiota–modulating effects. Widely used in functional foods, anti-fatigue supplements, and cosmeceuticals.
🔸 Cistanche Deserticola Polysaccharide
Derived from the thick stem of this desert herb, the polysaccharide shows antioxidant, anti-fatigue, memory-enhancing, and immune-boosting properties. It is gaining popularity in male vitality, cognitive support, and longevity applications.
🔸 Spatholobus Suberectus Polysaccharide
Extracted from the woody stem of this climbing herb, the polysaccharide exhibits hematopoietic, anti-thrombotic, and anti-inflammatory properties. It is used in traditional blood-nourishing formulas and modern skin-brightening and menstrual-support products.
🔸 Polygonatum Odoratum Polysaccharide
Sourced from the fleshy underground stem (rhizome) of Polygonatum odoratum, this polysaccharide functions as a natural prebiotic, supporting gut microbiota balance, bone health, and metabolic control. It is especially suited for postmenopausal care, digestive support, and anti-diabetic formulations.
🔸 Bletilla Striata Polysaccharide
Extracted from fleshy pseudobulbs, this polysaccharide is well known for its wound-healing, anti-inflammatory, and mucosal-repairing activities. It enhances collagen synthesis, reduces adhesions, and is widely used in topical gels, oral care, and post-operative applications.
🔸 Sargentodoxa Cuneata Polysaccharide
Derived from vine-like stems, this polysaccharide shows anti-inflammatory, antimicrobial, and detoxifying properties. Traditionally used in gynecological medicine, it is now being studied for broader applications in inflammatory and infectious diseases.
🔸 Aloe Polysaccharide
The inner gel of Aloe vera stems contains acemannan, a highly active polysaccharide with antiviral, anti-inflammatory, and immune-enhancing effects. It is a staple in topical skincare, digestive supplements, and wellness beverages.
🔸 Cucumis Melo Pedicel Polysaccharide
Extracted from the stem base (pedicel) of the melon plant, this rare polysaccharide exhibits respiratory-clearing, anti-edema, and detoxifying effects. Traditionally used to relieve lung heat and fluid retention.
