The ultraviolet-visible (UV) spectra, Fourier transform infrared radiation (FT-IR) spectra, nuclear magnetic resonance (NMR) spectra, zeta potential, surface characteristics, and conformational and thermal stability properties of PF40 were characterized. X-ray diffraction (XRD) and scanning electron microscopy (SEM), combined with Congo red test, revealed that PF40 powder has mainly existed in amorphous form with triple-helix conformation.

Polysaccharide structures often lack chromophore groups; thus, current analytical methods cannot distinguish polysaccharide metabolites in the body or polysaccharide prototypes in biological samples. Thus, the measurement of polysaccharides in blood, bodily fluid, and cell-culture medium is difficult.

However, little is known about the response of bacterial abundance, diversity, and community composition in the rhizosphere and non-rhizosphere soils under the sugarcane-peanut farming system. A field experiment was conducted with two treatments: sugarcane monoculture and sugarcane-peanut intercropping to examine the response of sugarcane parameters and edaphic factors.

The aim of this study was to evaluate the antioxidant and hepatoprotective activities and active ingredients in the powder from UCE (UCEP) through comparison with powder from hot water extraction (HWEP). The DPPH radical, ABTS radical, superoxide anion, total antioxidant activity, and ferric-reducing antioxidant power assay results showed that the UCEP exhibited stronger (P < 0.

Their structures were established on the basis of extensive spectroscopic analysis. Compound 1 showed moderate inhibitory activity and a known compound (3S,6S)-3-[(1R)-1-hydroxyethyl]-6-(phenylmethyl)-2,5-piperazinedione (5) showed weak inhibitory activity against α-glucosidase, respectively.
