Sinapis alba extract

Sinapis alba extract, commonly known as white mustard extract, is a complex phytochemical mixture derived from the seeds of the Sinapis alba plant rather than a singular therapeutic target molecule. Its primary bioactive profile includes the glucosinolate sinalbin, which undergoes enzymatic conversion by myrosinase into p-hydroxybenzyl isothiocyanate when exposed to moisture [1][2]. Traditionally, this extract is utilized in topical applications as a rubefacient and counter-irritant to alleviate muscular pain and respiratory congestion by inducing localized vasodilation [3][4]. At a molecular level, its components have been investigated for their ability to exert antimicrobial and antioxidant effects, potentially through the modulation of oxidative stress response elements like Nrf2 [1][5]. Because it is a crude botanical extract containing multiple chemical species, it does not possess a canonical protein target and is instead characterized by its broad multi-target pharmacological activity [2][3].

Exerts therapeutic effects primarily through its bioactive glucosinolate, sinalbin, which is hydrolyzed by the endogenous enzyme myrosinase into p-hydroxybenzyl isothiocyanate; this compound acts as a local irritant (rubefacient) to stimulate blood flow and may modulate Nrf2 and inflammatory cytokine pathways.
