Article Synopsis
- Vietnamese ginseng (Panax vietnamensis) is well-known for its medicinal properties, particularly due to bioactive compounds called ginsenosides found mainly in its rhizome.
- A recent study identified seven ginsenosides in the leaves of Vietnamese ginseng, notably ginsenoside Rd and pseudoginsenoside RS1, which showed significant inhibition of the enzyme acetylcholinesterase, important for memory function.
- The research suggests that the leaves could be an alternative source for enhancing memory, providing a basis for further exploration into their potential anti-dementia benefits.
Article Synopsis
- - The study focused on isolating compounds from the leaves of Ligustrum robustum and evaluating their anti-cancer effects, particularly against liver cancer cells (HepG2).
- - Seven compounds were isolated from the plant, including four lignans and three phenolic derivatives, with isocubein and 4-(2-acetoxyethyl)phenol showing the strongest inhibitory effects on cell growth and tumor development.
- - This research is the first to report the activity of L. robustum extracts and isolated compounds on HepG2 cells, paving the way for future studies in liver cancer treatment options.
The shape of energy dispersions near the band-edges plays a decisive role in the transport properties, especially the carrier mobility, of semiconductors. In this work, we design and investigate the γ phase of tin monoxide and monochalcogenides γ-SnX (X = O, S, Se, and Te) through first-principles simulations. γ-SnX is found to be dynamically stable with phonon dispersions containing only positive phonon frequencies.

Our calculations indicate that the Janus SnSSe monolayer is a semiconductor with an indirect band gap larger/lower than that of the SnSe/SnS monolayer. To obtain accurate estimates of the band gap, both Perdew-Burke-Ernzerhof (PBE) and Heyd-Scuseria-Ernzerhof (HSE06) hybrid functionals have been used and the effect of spin-orbit coupling has also been included.
