Bioavailability of Glucoraphanin and Sulforaphane from High‐Glucoraphanin Broccoli [PDF]

Molecular Nutrition and Food Research, 2018
ScopeBroccoli accumulates 4‐methylsulphinylbutyl glucosinolate (glucoraphanin) which is hydrolyzed to the isothiocyanate sulforaphane. Through the introgression of novel alleles of the Myb28 transcription factor from Brassica villosa, broccoli genotypes have been developed that have enhanced levels of glucoraphanin.

Glucoraphanin in Keimsaaten

Zeitschrift für Phytotherapie, 2023
ZusammenfassungAls eine vielversprechende Quelle für bioaktive pflanzliche Sekundärstoffe gelten Keimsprossen von Kreuzblütlerpflanzen (Familie: Brassicaceae). Vor allem das in Brokkolisprossen in höheren Konzentrationen vorkommende Glucoraphanin ist als bioaktiver Naturstoff von

Calcium affects glucoraphanin metabolism in broccoli sprouts under ZnSO4 stress

Food Chemistry, 2021
CaCl2, Ca2+ chelator (EGTA) and Ca2+ channel blocker (verapamil) were used to investigate mechanism of glucoraphanin metabolism in broccoli sprouts under ZnSO4 stress. CaCl2 treatment promoted sprout growth, reduced MDA (malonaldehyde) content and electrolyte leakage in sprouts under ZnSO4 stress.

The effect of processing and cooking on glucoraphanin and sulforaphane in brassica vegetables

Food Chemistry, 2021
Brassica vegetables are widely consumed mostly after processing and cooking. These processing and cooking methods not only can affect the taste, texture, flavor and nutrients of these vegetables, but also influence the levels of some important bioactive compounds, such as glucosinolates (GLSs).

The synthesis of isotopically labelled glucoraphanin for metabolic studies

Tetrahedron Letters, 2007
Abstract The first synthesis of a stable isotopically labelled derivative of the glucosinolate glucoraphanin, namely [10- 13 C,11,12- 2 H 5 ]glucoraphanin, is described. This also represents the first total chemical synthesis of glucoraphanin itself.

A total synthesis of ( R , S ) S -glucoraphanin

Tetrahedron, 2013
Abstract A total synthesis of (R,S)S-glucoraphanin (GRP) has been completed by a novel, simple and convenient method in high overall yield (17% over seven steps). The study describes a method for the synthesis of natural and unnatural (methylsulfinyl)alkyl glucosinolates (GLs) and also opens useful pathways to synthesize GRP as well as other sulfinyl

The Metabolic Fate of Purified Glucoraphanin in F344 Rats

Journal of Agricultural and Food Chemistry, 2007
Dietary broccoli is commonly eaten cooked, exposing individuals to intact glucoraphanin rather than to its hydrolysis product, the anticarcinogenic isothiocyanate sulforaphane, since cooking destroys the hydrolyzing enzyme myrosinase. There is little information on the absorption and metabolism of glucoraphanin, due partly to the lack of purified ...

Evaluation of the safety and bioactivity of purified and semi-purified glucoraphanin

Food and Chemical Toxicology, 2008
The anti-carcinogenic effects of broccoli have been attributed to sulforaphane, the hydrolysis product of glucoraphanin (GRP). Here we determined if purified GRP, in the absence of the plant-derived hydrolyzing enzyme myrosinase, could affect pulmonary and hepatic ethoxyresorufin O-deethylase (EROD) and/or NAD(P)H-quinone oxidoreductase 1 (NQO1 ...

Purification of a Sinapine-Glucoraphanin Salt from Broccoli Seeds

American Journal of Plant Sciences, 2010
A sinapine (sinapoylcholine)-glucoraphanin salt has been isolated from broccoli seeds and characterized by NMR and mass spectrometry. This salt extraction method can be used to purify glucoraphanin free from contamination by glucoiberin.

Glucoraphanin hydrolysis by microbiota in the rat cecum results in sulforaphane absorption

Food & Function, 2010
In the absence of the plant enzyme myrosinase, such as in cooked broccoli, glucoraphanin is considered to be hydrolyzed by bacteria in the lower gut to produce the bioactive isothiocyanate sulforaphane. Simulated digestion using US Pharmacopeia methods caused no loss of glucoraphanin, confirming that glucoraphanin is not destroyed by digestive enzymes ...
