TL;DR: Twelve undescribed 2-(2-phenylethyl)chromone derivatives, including one pair of enantiomers, together with eleven known ones, were isolated from the EtOAc extract of agarwood originating from Aquilaria filaria and revealed the potential of 2-( 2-phenylesthyl]chromones as α-glucosidase inhibitors.

TL;DR: Findings indicate that ACh-induced salt tolerance in N. benthamiana seedlings is mediated by the inhibition of antioxidant enzymes, activation of cell wall biosynthesis, and hormone signalling pathways.

TL;DR: The profile of glycolipid molecules, which form SD thylakoid membranes, seems to be species-specific and does not depend on the host's taxonomic position, in contrast, the betaine lipid molecular species profile of diacylglyceryl-3-O-carboxyhydroxymethylcholine (DGCC), which forms SD cell membranes, can be influenced by the host.

TL;DR: In this paper, eight undescribed diterpenoids, euphorfinoids E-L, together with twelve known analogues, were isolated from the roots of wild Euphorbia fischeriana.

TL;DR: Results support the concept of utilizing Aglaia species as a potential source for the production of biologically active compounds, and flavagline (rocaglamide) derivatives have been confirmed to exhibit exceptional cytotoxicity, and are, thus, considered lead compounds for further development.

TL;DR: In this article, 13 undescribed dammarane triterpenoid saponins (cypaliurusides A and M) were isolated from Cyclocarya paliurus.

TL;DR: In this article, a non-targeted metabolomics approach for the discrimination between fresh ginger rhizome samples collected from four different producing countries, i.e., China, India, Pakistan, and Peru, is presented.

TL;DR: In this article, the kinetics and exact mechanism of the peroxyl radical scavenging activity of CARS in the gas phase and under physiological conditions were investigated in aqueous solution.

TL;DR: An overview of the known chemical diversity of taxanes, with an emphasis on the functionalization of diterpene scaffolds, is provided in this paper, where the implications of the occurrence of chemically diverse taxane metabolites for unraveling Taxol biosynthesis and enabling pathway engineering are discussed as well.
