Alhagi pseudalhagi , commonly known as camel thorn, is used as an indigenous medicinal plant in China. The present study was designed to elucidate the structure of a novel polysaccharide, APP90-2, isolated from Alhagi pseudalhagi and evaluate its osteogenic activity. A homogeneous polysaccharide (APP90-2) was obtained from A. pseudalhagi via DEAE-52 and Sephacryl S-100 columns, with a molecular weight of 5.9 kDa. Monosaccharide, GC–MS, and NMR analyses showed that APP90-2 consisted of α - l -Rha p -(1→, →3)- α - l -Ara f -(1→, →5)- α - l -Ara f -(1→, →4)- β - d -Xyl p -(1→, α - d -Glc p -(1→, →3,5)- α - l -Ara f -(1→, →4)- β - d -GlcA p -(1→, →4)-3-OAc- α - d -Glc p -(1→, →3)- α - d -Gal p -(1→, →3)- β - d -GalA p -(1→, →4)- α - d -Gal p -(1→, →6)- α - d -Man p -(1→, →4,6)- β - d -Gal p -(1→, and →3,6)- β - d -Glc p -(1→ with relative molar ratios of 4.1:1.8:6.1:6.7:1.7:1.0:1.5:2.7:2.4:1.1:2.3:2.6:1.4:2.0. Morphological analyses revealed that APP90-2 interacted with Congo-red and had an obvious honeycomb structure. Additionally, APP90-2 significantly promoted proliferation, differentiation, and mineralization of MC3T3-E1 cells, indicating that APP90-2 exhibited pronounced osteogenic activity. Therefore, our findings suggest that A. pseudalhagi may be used as an alternative medicine or health supplement for the prevention and treatment of osteoporosis.

This study investigated the structure of acid Alhagi camelorum Fischa polysaccharide (aAP) and its impact on intestinal activity in mice. The results showed that aAP comprised of the fucose, arabinose, rhamnose, galactose, glucose, xylose, mannose, galacturonic acid, glucuronic acid with the molar ratio of 0.81:14.97:10.84:11.14:3.26:0.80:0.80:54.92:2.47 with the molecular weight (Mw) of 22.734 kDa. Additionally, the composition of aAP was assessed via FT-IR, methylation, and NMR analyses, indicating that the backbone of the aAP was consisted of →4)-α-D-Gal p A-6-OMe-(1 → 4)-α-Gal p A-(1 → and →4)-α-D-Gal p A-6-OMe-(1 → 2)-α-L-Rha p -(1→, as well as →4)-β-D-Gal p - and →5)-α-L-Ara f - for the branched chain. Furthermore, ICR mice underwent intragastric administration of different concentrations of aAP for 7 consecutive days. The results showed that aAP enhanced the murine spleen and thymus indices, promoted the secretion of serum lgG antibody, intestinal lgA antibody and intestinal cytokines, improved the morphology of intestinal villi and crypts, enhanced quantity of intestinal IELs and IgA+ cells, and activated T lymphocytes and DC cells in MLNs. In summary, these findings suggest that the utilization of aAP could enhance the immune response of the murine intestinal mucosa.
