Chemical diversity and phylogenetic insights into Hawaiian ʻākia (Wikstroemia) species used in traditional fishing practices

PLANTS, PEOPLE, PLANET, EarlyView.
Traditional fishing with plant‐based piscicides is a global practice in decline, facing increasing restrictions. We investigated the chemical diversity of endemic Wikstroemia species historically used to stun or poison fish in Hawaiʻi. Using 1‐H‐NMR, principal component analysis, targeted HPLC, and target‐capture sequencing, we characterized compounds ...

Raphani Semen Extract Targets the las Quorum Sensing System to Suppress Pseudomonas aeruginosa Biofilm and Signal Molecule Production

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
Raphani Semen extract (RSE) and its characteristic isothiocyanates sulforaphane (SFA) and sulforaphene (SFE) inhibit Pseudomonas aeruginosa biofilm formation and virulence by targeting the las quorum sensing system. RSE reduces the autoinducer 3‐oxo‐C12‐HSL, downregulates QS genes, and suppresses motility and virulence factors. SFA and SFE recapitulate
