The fine structure and chain conformation of a heteropolysaccharide (PCIPS3) from mycelium of Paecilomyces cicadae were investigated via the analysis of HPLC, IR, methylation, NMR spectroscopy and multiangle light scattering. It was determined to be a 2.23 × 104 g/mol heteropolysaccharide primarily composed of glucose, galactose and mannose in a molar ratio of 23.8:2.1:1.0. The PCIPS3 backbone consisted of 1,4-linked α-D-Glcp and 1,4-linked 6-O-Me-α-D-Glcp residues, which were occasionally interrupted by branched β-Galf residues through 1,6-linkage. Moreover, the α (0.60) from Mark–Houwink–Sakurada (MHS) equation suggested that PCIPS3 adopted a flexible chain conformation in 0.1 mol/L NaNO3 at 25 °C. The worm-like chains model parameters for PCIPS3 were estimated as following: ML = 437 nm?1, q = 0.46 nm and 0.79 nm, which were further evidenced by AFM. Furthermore, PCIPS3 showed excellent scavenging capacities of 2,2-diphenyl-1-picrylhydrazyl radical, superoxide radical, hydroxyl radical, ORAC radical and moderate immunomodulatory activity.

Fucogalactans from edible Agaricus bisporus (RFP-Ab) and wild Lactarius rufus (RFP-Lr) mushrooms were obtained on aqueous extraction followed by purification. RFP-Ab had Mw 43.8 × 104 g mol -1 and RFP-Lr Mw 1.4

Two new sterylacyl glucosides, sitoindosides I and II, isolated from the fruits of musa paradisiaca (banana, vegetable variety), have been assigned sitosterol 3-(6-O-palmitoyl-β-D-glucopyranoside) (1) and sitosterol 3-(6-O-oleoyl-β-D-glycopyranoside) (2) structures on the basis of spectroscopic analysis and chemical transformation.A 5:1 mixture of (1) and (2) (in doses of 50 mg/kg, oral administration) provided complete protection against aspirin-induced ulcer in albino rats and was free from any toxicity.
