Skin Whitening Effects of Estragole Derivatives

open access: yesJournal of Oleo Science, 2003
It was previously confirmed that estragole, an essential oil obtained from Foeniculum vulgare Miller , has skin whitening effects. Furthermore, compounds synthesized from estragole have good tyrosinase inhibitory activity. We have therefore used estragole as a starting material to synthesize novel the compounds containing sulfur and oxygen that atoms ...

Ru-Catalyzed Estragole Isomerization under Homogeneous and Ionic Liquid Biphasic Conditions [PDF]

open access: yesACS Omega, 2017
The isomerization of estragole to trans-anethole is an important reaction and is industrially performed using an excess of NaOH or KOH in ethanol at high temperatures with very low selectivity. Simple Ru-based transition-metal complexes, under homogeneous, ionic liquid (IL)-supported (biphasic) and "solventless" conditions, can be used for this ...

Quantitation of estragole by stable isotope dilution assays

open access: yesLWT - Food Science and Technology, 2009
Abstract Various calibration strategies for the quantitation of the phenylpropane estragole by gas chromatography–mass spectrometry were developed and compared. For application in stable isotope dilution assays, two deuterium labelled estragole isotopologues were synthesized. Of these, [3′,3′-2H2]estragole was prepared by Wittig reaction of 4-methoxy-
