Structures and immunomodulatory activity of one galactose- and arabinose-rich polysaccharide from Sambucus adnata.

One galactose- and arabinose-rich polysaccharide isolated from Sambucus adnata was named SPS-1, which had an average molecular weight 138.52 kDa, and was composed of L-rhamnose, D-glucuronic acid, D-galacturonic acid, D-galactose, and L-arabinose in a molar ratio of 0.6:0.

The seed oil of ameliorates Aβ25-35-induced Alzheimer's disease in rats.

, a plant of the Paeoniaceae family, has abundant genetic diversity in different populations, and the seed oil can be used in a diverse number of activities. However, its neuroprotective effect is not clear. We investigated the memory-improving effects and associated mechanisms of seed oil (PLSO) on amyloid beta (Aβ)25-35-induced Alzheimer's disease (AD) in rats.
