Glucosinolates
being as powerful as
Imperial Gold Maca
with it's unique process
that allows the
Glucosinolates
to produce a very medicinal affect.

They are found
exclusively in dicotyledenous plants, with
highest concentrations in the
Brassicaceae (Cruciferae)
families. |
Brassica plants
such as winter rape, turnip, cabbage, broccoli, and kale
are rich in sulfur containing compounds called
glucosinolates. These plants are currently receiving
renewed attention as important dietary sources of
compounds (primarily glucosinolates and anti-oxidants)
which protect against cancer. Glucosinolate
concentrations vary within and between different species
and subspecies of Brassica. For example,
glucosinolate levels were examined in five subspecies
and sixty-five accessions of Brassica oleracea
(including 50 broccoli accessions) grown under the same
cultural conditions. Among commercially grown broccoli
cultivars, "Brigadier" contained 3.5 and 6.4-fold higher
total glucosinolates than "Packman" and "Baccus". About
80% of the total glucosinolates in broccoli are present
as glucoraphanin (4-methyl-sulphinylbutyl glucosinolate),
an aliphatic glucosinolate. When glucoraphanin comes in
contact with myrosinase it breaks down into sulforaphane
-- one of the most potent anti-cancer compounds in
Brassicas.
Glucosinolates in
Brassicas also have figured prominently in the
evolution of these plants' chemical defenses to
herbivores, plant pathogens, and weeds. With insect
herbivores, glucosinolates in short-lived
(non-perennial) plants are proposed to act at low
concentrations primarily as qualitative defenses against
nonadapted generalist herbivores while specialist
herbivores, on the other hand, are able to overcome
glucosinolates, even to the point of using them as
feeding and oviposition stimulants. Nevertheless, the
effects of glucosinolates on both generalist and
specialist herbivores may be determined by the specific
glucosinolates present and their concentrations. For
example, maximum herbivory on naturalized mustard plants
(Brassica rapa) by two crucifer insect
specialists, the flea beetle Phyllotreta cruciferae
and the diamondback moth, occurred at intermediate
glucosinolate levels. Thus the specific glucosinolates
and their concentrations present in certain Brassica
cultivars, in combination with correlated resistance
factors, might be used to affect populations of some
insect pests specializing on crucifers.
Glucosinolates in plant material decomposing in the soil
may be converted into organic isothiocyanates,
thiocyanates, and nitriles which reduce weed seed
germination. In potatoes, with fall-planted and
spring-incorporated "Juniper" winter rape (Brassica
napas), weed biomass was reduced 96% when common
lambsquarter (Chenopodium album) and 50% when
redroot pigweed (Amaranthus retroflexus) were
the major weed species. In one study total glucosinolate
levels were higher in Brassica napas roots than
in shoots. But Brassica shoots have been
generally found to be more active than roots against
weeds. One reason may be the specific glucosinolate
found in each portion of the plants. In roots,
phenylethyl glucosinolate made up to 80% of the total
glucosinolates, while in shoots four compounds
(4-pentenyl glucosinolate and 3-butenyl glucosinolate
and their 2- hydroxy derivatives) made up to 90% of the
total glucosinolates. The later compounds may have more
activity against seed germination or may persist longer.
The concept of incorporating Brassica residues
for weed control and to suppress other soil-borne pests
is biofumigation. The incorporation of Brassica
may even have a role in replacing methyl bromide as that
product is phased out.
Plant
breeders are developing Brassica genotypes that
produce high levels of glucosinolates to help fight
cancer. They should also consider the pest suppressive
capabilities of glucosinolates. In the future, not only
will it be important to eat your broccoli to remain
healthy, but growing broccoli high in glucosinolates
might also be an important tactic in biological control.
