A novel low-molecular-mass pumpkin polysaccharide: Structural characterization, antioxidant activity, and hypoglycemic potential

The novel natural low-molecular-mass polysaccharide (SLWPP-3) from pumpkin (Cucurbia moschata) was separated from the waste supernatant after macromolecular polysaccharide production and purified using a DEAE cellulose-52 column and gel-filtration chromatography. Chemical and instrumental studies revealed that SLWPP-3 with a molecular mass of 3.5 kDa was composed of rhamnose, glucose, arabinose, galactose and uronic acid with a weight ratio of 1: 1: 4: 6: 15, and primarily contained →3,6)-β-D-Galp-(1→, →4)-α-GalpA-(1→(OMe), →4)-α-GalpA-(1→, →2,4)-α-D-Rhap-(1→, →3)-β-D-Galp-(1→, →4)-α-D-Glcp, and →4)-β-D-Galp residues in the backbone. The branch chain passes were connected to the main chain through the O-4 atom of glucose and O-3 atom of arabinose. Physiologically, the ability of SLWPP-3 to inhibit carbohydrate-digesting enzymes and DPPH and ABTS radicals, as well as protect pancreatic β cells from oxidative damage by decreasing MDA levels and increasing SOD activities, was confirmed. The findings elucidated the structural types of pumpkin polysaccharides and revealed a potential adjuvant natural product with hypoglycemic effects.

Allelopathic effect of triterpenoid saponins from the stems of lathyrus aphaca linn

Two new triterpenoid saponins have been isolated from the methanolic extract of the stems of the Lathyrus aphaca Linn. A new compound 1 has m.p. 295?297°C, m.f. C47H78O16, [M]+ m/z 898 was characterized as 3-O-[β-D-galactopyranosyl-(14)]-β-D-xylopyranosyl-3β,11α,28-trihydroxy-olean-12-ene-28-O-α-L-rhamnopyranoside and compound 2 has m. p. 289-291°C, m.f. C46H76O16, [M]+ m/z 884 was characterized as 3-O-[β-D-xylopyranosyl-(1→4)]-β-D-glucopyranosyl-(1→4) α-L-arabinofuranosyl 2α,3β,19α-trihydroxy-olean-12-ene by various color reactions, chemical degradations, and spectral analysis. From experimental findings, it was concluded that both compounds 1 and 2 have shown allelopathic effects on the growth of shoot length of the seeds of Zea mays (L.).

New antifungal triterpenoid saponin from launaea pinnatifida cass

A new triterpenoid saponin (compound 1), 3β-O-[α-L- rhamnopyranosyI-(l→3)-O-α-L-arabinopyranosyl-(l→3) -O-β-D-galactopyranosyl]-spergulatriol along with known compounds glutenol and hopenol-b have been isolated from the methanol soluble fraction of the defatted seeds of the plant and structurally elucidated by various colour reactions, chemical degradations and spectral analysis. Compound 1 shows antifungal activity against various fungi.
