Chen, Xiaoxia published the artcileStructural characterization and osteogenic bioactivities of a novel Humulus lupulus polysaccharide, Safety of (2R,3S,4S,5R)-2,3,4,5,6-Pentahydroxyhexanal, the main research area is Humulus osteoporosis osteogenicity polysaccharide.
The female flowers of H. lupulus are also used in traditional Chinese medicine, but the biol. active ingredients underlying its benefits remain unclear. In this study, we isolated a homogeneous polysaccharide (HLP50-1) with a mol. weight of 49.13 kDa from female flowers of H. lupulus via a DEAE-Cellulose 52 anion exchange column and a Sephadex G-75 gel filtration column. Methylation, GC-MS, and NMR analyses revealed that the HLP50-1 comprised (â?)-α-D-Glcp-(1â? â?)-α-D-Manp-(1â? â?)-α-L-Rhap-(1â?, β-D-Glcp-(1â?, α-L-Araf-(1â? â?,6)-2-OAc-β-D-Galp-(1â? β-D-Galp-(1â? â?,6))-β-D-Glcp-(1â? â?,3,4)-α-D-Xylp-(1â? â?)-α-D-Glcp-(1â? â?)-α-D-Galp-(1â? â?)-α-D-Galp-(1â?. Advanced structural anal. showed that the HLP50-1 contained irregular fragments of different sizes and shapes with a smooth surface. The aggregates appeared be composed of accumulated crystals. Furthermore, the osteogenic activities of the HLP50-1 were evaluated via MC3T3-E1 cells in vitro. The results showed that 0.13μM HLP50-1 led to outstanding proliferation, differentiation, and mineralization of the MC3T3-E1 cells. Therefore, HLP50-1 has osteogenic effects, and it may be a candidate for the treatment of osteoporosis. It has broad application prospects in functional foods, health-care products, and pharmaceuticals.
