“…Variation of GSL composition and concentration in Brassica vegetables is caused by many factors: varieties, different plant organs and development stages, growing and environmental conditions, post-harvest storage and handling procedures (Jeffery et al, 2003;Vallejo et al, 2002). The concentration of potentially health beneficial GSLs for a given species has been found to be greater in seed sprout vegetables are scarce and much of the literature still focuses upon either fully grown plants of B. oleracea crops (Charron et al, 2005;Ciska et al, 2000;Kushad et al, 1999) or seeds (Mattaus and Luftmann, 2000;West et al, 2004). De March et al (1989 examined the variation of GSLs content during pod and seed maturity.…”

The objective of this study was to evaluate glucosinolate (GSL) profiles and variation of total and individual GSLs concentrations within seedling (0-14 days) and growth stages (0-15 weeks) of Korean Chinese cabbage (Brassica rapa L. ssp. pekinensis). Ten GSLs (progoitrin, glucoraphanin, glucoalyssin, gluconapin, glucobrassicanapin, 4-hydroxyglucobrassin, glucobrassicin, 4-methoxyglucobrassicin, neoglucobrassicin and gluconasturtiin) were identified from Korean Chinese cabbage. In general, total GSL content significantly decreased during seedling (from 92.89 to 35.26 μmol･g -1 DW) and growth stages (from 74.11 to 1.97 μmol･g -1 DW). Gluconapin was the highest in seeds and in the germination period (73.1 μmol･g -1 DW) and declined gradually from 73 to 15% during seedling stages. The level of the major aliphatic GSLs, gluconapin and progoitrin, tended to decrease sharply, whereas levels of indolic GSLs (4-methoxyglucobrassicin, glucobrassicin) and aromatic GSLs (gluconasturtiin) were found to increase generally at the beginning of growth stages.

“…The concentration of potentially healthbeneficial glucosinolates for a given species has been found to be greater in sprouts than in fully grown plants (Fahey et al, 1997). However, studies of the glucosinolate content of the growing sprouts are scarce and much of the literature still focuses upon either fully grown plants of Brassica oleracea crops (Charron et al, 2005;Ciska et al, 2000;Kushad et al, 1999) or seeds (Matthaus and Luftmann, 2000;West et al, 2004). The rapid changes in glucosinolate profile that occur during germination and early seedling growth (Brown et al, 2003;Clossais-Besnard and Larher, 1991;Petersen et al, 2002;West et al, 2004) make the duration of the sprouting period to be a particularly relevant factor in maximizing the concentration of the desirable bioactive compounds.…”

Consumption of plants of the species Brassica oleracea is related to a decreased incidence of certain cancer forms in humans, and this has been linked to the presence of glucosinolates in those vegetables. After ripe seeds, sprouts of some brassicaceous plants contain the highest concentration of these compounds and are therefore a good source of glucosinolates for chemoprotection. In the present experiments, the content and distribution of glucosinolates was determined in ripe seeds and sprouts (seedlings) of five varieties of B. oleracea (white cabbage, red cabbage, Savoy cabbage, broccoli and cauliflower) by high performance liquid chromatography. The type and concentration of individual glucosinolates varied according to variety of B. oleracea, plant parts in which they occurred and the sprouting period of the seed. Concentration of alkyl glucosinolates decreased whereas that of indol-3-ylmethylglucosinolates increased throughout the sprouting period. Roots had the highest glucosinolate concentration in four and seven day old sprouts whereas at both sprouting times, cotyledons had the highest concentration of alkylthio-and alkylsulphinylglucosinolates. #

Six kaempferol glycosides, four of them characterized for the first time, were isolated from the leaf extract of Lobularia maritima. The structural elucidation was performed by a combined approach using Electrospray-Ionization Triple-Quadrupole Mass-Spectrometric (ESI/TQ/MS) techniques, and 1D- and 2D-NMR experiments (1H, 13C, DEPT, DQ-COSY, TOCSY, ROESY, NOESY, HSQC, HMBC, and HSQC-TOCSY). The isolated kaempferol derivatives have different disaccharide substituents at C(3) and four of them have a rhamnose unit at C(7). To evaluate their potential allelopathic role within the herbaceous plant community, the compounds, as well as the aglycone obtained from enzymatic hydrolysis, have been tested in vitro on three coexisting plant species, Dactylis hispanica, Petrorhagia velutina, and Phleum subulatum. The results obtained allow us to hypothesize that the type of the sugar modulates the biological response. The bioassay data, analyzed by a multivariate approach, and grouping the compounds on the basis of the number of sugar units and the nature of carbohydrates present in the disaccharide moiety, indicate a structure-activity relationship.
