Three new pentacyclic triterpenes isolated from Gilg. and their cytotoxic evaluation.

Three new pentacyclic triterpenes, henninglupal (), 19-ethylene henningsyl (), and 19-ethylene henningsal (), along with the previously reported crystal heninngsal () and alpha-amyrin acetate () were isolated from a methanolic extract of the bark of Gilg. The new pentacyclic triterpenes were elucidated through comprehensive spectroscopic analysis, including 1D, 2D NMR, and High-resolution LCMS. The MTT cytotoxicity of compound - was evaluated on Caco-2 cell lines, where all the isolated compounds exhibited low cytotoxic effects up to concentrations of 125 µM.

Three new proaporphine alkaloids from L.f. and their cytotoxic evaluation.

Three new proaporphine alkaloids, cissamaline (), cissamanine (), and cissamdine (), along with two known compounds ( and ) were isolated from total tertiary alakloidal extracts of the leaves and stems of . The new alkaloids were elucidated through comprehensive spectroscopic analysis, including 1 D, 2 D NMR and High-resolution LCMS. The MTT cytotoxicity was evaluated on Caco-2 cell lines, where all the isolated compounds exhibited cytotoxic effects at concentrations above 250 µM.

Organic chemical devulcanization of rubber vulcanizates in supercritical carbon dioxide and associated less eco-unfriendly approaches: A review.

There is a growing need to recover raw materials from waste due to increasing environmental concerns and the widely adopted transition to circular economy. For waste tyres, it is necessary to continuously develop methods and processes that can devulcanize rubber vulcanizates into rubber products with qualities and properties that can closely match those of the virgin rubber. Currently, the most common, due to its efficiency and perceived eco-friendliness in recovering raw rubber from waste rubbers, such as tyres, is devulcanization in supercritical carbon dioxide (scCO) using commercial and typical devulcanizing agents.

Isolation and characterisation of altissimin: a novel cytotoxic flavonoid -apioglucoside from ().

Flavonoids are a class of biologically active compounds with various proven nutraceutical benefits. In flavonoid -glycosides, the aglycones are attached to sugar residues cleavage-resistant C-C bonds which alter typical flavonoid pharmacokinetic properties. In these compounds, the combination of biological activities from the flavonoid moieties and sugar residues create unique and more diverse biological functions than those of -glycosylated and unsubstituted flavonoids.
