Forestry biomass is a by-product which commonly ends up being burnt for energy generation, despite comprising valuable bioactive compounds with valorisation potential. Leaves of Acacia dealbata were extracted the first time by supercritical fluid extraction (SFE) using different conditions pressure, temperature and cosolvents. Total yield, individual triterpenoids yields concentrations assessed...
Two new triterpenoids namely, 3α-hydroxyferna-7, 9(11),22-trien-12-one (1) and 3α-acetoxyferna-7, 9(11)-dien-22-ol (2) along with two known compounds 3α,16α-dihydroxyferna-7,9(11)-dien-12-one (3) and 3α,16α-dihydroxyferna-8-en-11-one (4) were isolated from Lonicera quinquelocularis. Their structures were elucidated by chemical and modern spectroscopic techniques. All the compounds showed good a...
Micellization and solution properties of the aglycon triterpenoids asiatic acid (AA) and madecassic acid (MA) were examined experimentally and in computational simulations. AA and MA belong to the large class of bioactive aglycon triterpenoids, for which limited physicochemical data are available. In this study, solubility, partition coefficient, critical micelle concentrations (CMC), and surfa...
Two novel lanostane-type triterpenes, Ganolactone B and Ganoderiol A triacetate, were isolated from the fruiting bodies of G. sinense, together with six known compounds. The structures of the two new triterpenes were determined as 3beta,7beta- dihydroxy-11,15-dioxo-lanosta-8-en-24-->20 lactone (1) and 3beta,24,26-triacetoxy-5alpha-lanosta-7,9(11)-dien-25-ol (2), respectively, by chemical and sp...
