TL;DR: The results suggest that saponins from S. chinensis improve glucose uptake and catabolism in hepatic cells by stimulating the AMPK and the IR/IRS-1/PI3K/Akt signaling pathways.

TL;DR: In this article, the interaction between pterodontic acid (PA) and bovine serum albumin (BSA) was studied using a fluorescence quenching technique, ultraviolet-visible spectrophotometry and dynamic light scattering (DLS).

TL;DR: Bioassay-guided phytochemical investigation of the EtOAc fraction from the leaves of a Chinese medicinal herb, Eucalyptus citriodora Hook, resulted in the isolation of a new compound rhodomyrtosone E, along with 12 known compounds.

TL;DR: A new triterpene named methyl 3β-O-p-hydroxy-E-cinnamoyloxy-2α,23-dihydroxyolean-12-en-28-oate is presented for the first time, and compound 2 displayed significant free-radical-scavenging activity which is similar to that of standard antioxidant ascorbic acid (VC and therefore may be a promising natural antioxidant.

TL;DR: Two eudesmane-type sesquiterpenes, 9α-hydroxycurcolonol (1 ) and 3αhydroxy-4-deoxy-5-dehydrocurcolonabolol (2 ), along with nine known sesQUERPES (3, 11 ) were isolated from the roots of Chloranthus angustifolius.
