Structural characterization of a homopolysaccharide with hypoglycemic activity from the roots of Pueraria lobata

“…Additionally, the signals for carbon and hydrogen for PLP-1 are fully shown in Table 2 according to the HMBC spectrum and the literature. [36][37][38][39][40]…”

A Review: The Bioactivities and Pharmacological Applications of Phellinus linteus

“…Recently, some studies revealed that caffeic acid, inotilone, and 4-(3,4-dihydroxyphenyl)-3-buten-2-one (0.1–1 mM) from the mycelium of P. linteus showed dose-dependent antioxidative effects in ABTS and DPPH radical-scavenging activity assays, while phellilane H, (2E,4E)-(+)-4′-hydrox did not have any effects [24]. Yan et al [25] revealed that the dose-dependent anti-aging activity of polysaccharides of P. linteus was closely related to the antioxidative activity in D-galactose-induced aging model mice. The results showed that polysaccharides (100, 200, and 400 mg/kg) of P. linteus treated for 40 days markedly increased the activity of SOD, catalase (CAT), and GSH-Px, and significantly reduced the malondialdehyde (MDA) content of serum and livers [25].…”

Administration of 300, 600, and 1200 mg/kg/d chitosan oligosaccharide (a natural polysaccharide) to aged rats induced using D-galactose (250 mg/kg/d) for eight weeks significantly increased the activity of CAT, GSH-Px, and SOD and decreased the content of MDA [26].…”

“…This role has been attributed to the biological activity of its various components, including polysaccharides, triterpenoids, polyphenols, and pyrans. Based on modern pharmacological studies, P. linteus is reported to have multifaceted biological activities, including anti-inflammatory [6,7,8,9,10,11,12,13,14], immunomodulatory [15,16,17,18,19], antioxidative [20,21,22,23,24,25,26], antimicrobial, and antiviral [27,28,29,30,31,32,33], as well as anticancer [34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57], antidiabetic [58,59,60,61,62,63,64,65,66,67], hepatoprotective […”

Protective effects of enzyme degradation extract from Porphyra yezoensis against oxidative stress and brain injury in d-galactose-induced ageing mice

“…In vivo assessment of the effects of Porphyra yezoensis enzyme degradation extract on D-galactose-treated mice Animals and experimental design. Female ICR mice (27,28) (18-20 g) at 3 weeks of age were purchased from Vital River Laboratory Animal Centre (Beijing, China; Licensed ID: SCXK2012-0001). Animals were kept in a polyacrylic cage and maintained under constant conditions (room temperature 23 ± 1°C and humidity 50 ± 10 %) with alternative 12 h light-12 h dark cycles.…”
