Auricularia auricula(AA)and Auricularia polytricha(AP)are popular edible *** study successfully produced hypoglycemic polysaccharides from un-smashed or smashing and sieving(through a 10-mesh sieve)AA and AP(termed as AAP/AAP-10 and APP/APP-10)via scalable processes(water extraction,ethanolic precipitation and deproteinization).This is the first report to co.pare the effectiveness of AAP and APP in co.bating streptozotocin-induced oxidative stress and diabetes-related changes in mice(body weight,fasting blood gluco.e,serum insulin,proinflammatory mediator and cytokines,oxidative stress-related products,antioxidant enzymes).APP and AAP with different molecular weights and monosaccharide molar ratios co.ld be therapeutic options for diabetes with a low dose(100 mg/kg/day)likely working *** the same dose,APP generally performed more effective than AAP,and AAP-10/APP-10 seemed slightly more beneficial than AAP/*** mechanism underlying these antidiabetic functions might involve the NF-κB and associated signalling *** is cheaper than AA,thereby representing a favorable source of functional polysaccharides.

A polymer （poly（9,10）anthracenevinylene-alt-4,4＇-（9,9-bis（4-（4＇-（1,2,2＇-triphenyviny）phenoxy）butyl）-9H- fluorene-2,7-diyl） dibenzaldehyde）, P1） was successfully synthesized through the Wittig-Horner reaction by employing fluorene and 9,10-distyrylanthracene moieties as building blocks for backbone and tetraphenylethenes as pendant groups. Photophysical and thermal properties of the resulting polymeric emitter were fully characterized by ultraviolet-visible （UV- Vis） absorption and photoluminescence （PL） spectra, thermogravimetric analysis （TGA） and differential scanning calorimetry （DSC）. While P1 emits an orange-light centered at 567 nm in dilute tetrahydrofuran （THF） solution, the solid powder of the polymer exhibits strong yellow emission peaked at 541 nm. It is also found that the as-synthesized polymer shows unique property of aggregation-enhanced emission （AEE）. In addition, P1 possesses high thermal stability with a deco.position temperature （Td,5%） of 430 ℃ and high morphological stability with a glass transition temperature （Tg） of 171℃. Under the stimulus of mechanical force, the emission of P1 can be changed from yellow to red （△λmax = 61 rim）, showing a remarkable mechanochromism. The results from XRD analysis suggest that such mechanochromic phenomenonof PI is probably caused by the destruction of crystalline structure, which leads to the co.formational planarization of the distyrylanthracene moieties forming by the polymerization and the increase of molecular co.jugation of the backbone.
