Four new 2,3-secodammarane triterpenoids, stellatonins A-D (3-6), together with a new 3,4-secodammarane triterpenoid, stellatonin E (7), and the known silvestrol (1), 5‴-episilvestrol (2), and β-sitosterol, were isolated from a methanol extract of the stems of Aglaia stellatopilosa through bioassay-guided fractionation. The structures of the new compounds were elucidated using spectroscopic and chemical methods. The compounds were evaluated for their cytotoxic activity against three human…

  • 2021
Broad-based comparison revealed characteristic substitution trends which contribute as chemical markers to natural delimitation and grouping of taxonomically problematic Aglaia species and were shown to be not only promising anticancer agents but gained now also high expectations as agents against emerging RNA viruses like SARS-CoV-2.

Chemical Constituents of Aglaia odorata Leaves and Their Anti-inflammatory Effects

The phytochemical investigation resulted in the isolation of four constituents hesperetin-7,3’-O-dimethylether, 5α-dammar-20-ene-3β,24,25-triol, odorine, and odorinol; all compounds suppressed LPS-induced TNF-α expression in rat immortalized microglia HAPI cells and showed most potent inhibitory effect.
