English: Hairy Bitter-cress Français: Cardamine hérissée Deutsch: Behaartes Schaumkraut Wetenschappelijk: Cardamine hirsuta Familie: Kruisbloemenfamilie, Brassicaceae (Cruciferae) Mijn ideale wilde plant om op te eten. Pittig, zacht: door de sla, in de aardappelpuree, in de omelet..... Een soort pesto veldkers met : - Maak een busseltje kleine veldkers fijn. - Plet een teentje knoflook (of een bolletje en pijpjes kraailook) - Doe veldkers en look samen met geroosterde pijnboompitten, een snufje zout, een beetje olijfolie en vers geraspte Parmezaanse kaas in een vijzel en wrijf goed fijn. Doseringen? een beetje meer olie als het geheel te droog blijft, wat meer kaas als het te vloeibaar is. Gewoon beginnen met een klein beetje olie en een beetje kaas, en beetje bij beetje olie toevoegen tot je een goeie consistentie hebt.

A hot cress-like flavour, they are mainly used as a garnish or flavouring in salads etc but are also sometimes used as a potherb. The plant germinates most freely in the autumn and so leaves are usually available all winter. Glucosinolates in wild Brassicacea Cardamine hirsuta and Brassica juncea Certain sulfur-containing chemicals with pungent bitter taste are produced within the plants themselves, which are known as glucosinolates. The family specific chemicals are the part of mustard-oil glycosides (glucosinolates) which defend the plants against herbivores and microorganisms [2]. Glucosinolates and their metabolites also act as anti-tumor agents. The glucosinolate-myrosinase system is considered as one of the best studied plant chemical defenses. Beside this, the glucosinolates are non-toxic. It may be a wise approach to incorporate these edible and medicinal associates into our diets. Studies have shown that increased intakes of cruciferous vegetables are linked with a reduced threat of prostate cancer, colon cancer, lung cancer and breast cancer [3] [4]. Research studies routinely show that wild varieties generally include higher levels of nutritional and medicinal compounds than their cultivated counter parts.

metabolities contents in leaves of B. juncea and

clearly indicated the presence of various
phytochemicals like tannin, flavonoid, alkaloid,
anthocyanidin and phenols. This project focused
on glucosinolates derived from Brassica juncea
L and Cardamine hirsuta L. leaves and seeds.
The study revealed that raw Cardamine hirsuta
seeds showed the highest levels of
glucosinolates compared to the Brassica juncea
seeds. The results of this study showed that
Cardamine hirsuta is a rich source of
glucosinolates. The compound was detected at
230nm using the UV Spectrophotometer [13,
14]. Though further work to characterize the other
chemical constituents and perform quantitative
estimation with marker compounds is also
necessary these data can also be considered
along with the other values for fixing standards
to this plant. Organic extracts of plants of
Brassica juncea and Cardamine hirsutaleaves
was separated for comparing its Glucosinolate
content. Thus it can be concluded that
Cardamine hirsuta contains 50.69%
Glucosinolate comparatively more than Brassica
juncea extract which is 18.88%. The study revealed
that raw Cardamine seeds and leaves showed the
highest level of glucosinolates compared to the
raw mustard seeds and leaves samples when
analyzed by U.V. spectrophotometer and by
HPTLC methods [10, 11,12]. Discussion: This study deals with the
morphological study of Cardamine hirsuta plant
which is the basis to know the life cycle to grow
the plant with appropriate necessities and fruitful
yield and for systematic study. Cardamine
hirsuta was used in comparison of the
commercial Brassica juncea plant to compare
the secondary metabolite contents.
Phytochemical screening of both the plants was
carried out qualitatively. It is reported that
Mustard has antibacterial, antifungal and
anticancerous activity [13]. These activities
may be attributed to various phytochemicals
present in the extract. Tannin is reported to have
antimicrobial activity and antibacterial activity. Further a specific secondary metabolite;
Glucosinolate of great importance was then
chosen and quantified. Comparative study of
glucosinolate levels in commercial Brassica
juncea and wild weed Cardamine hirsuta was
carried out. The dietary intakes of glucosinolates
showed various benefits to health. The Levels of
leaf glucosinolates are known to regulate during
plant development. Mechanical damage or insect
feeding. A three step process to obtain main
glucosinolate from Brassica junecea and
Cardamine hirsuta was carried out. The steps
involved extraction with methanol, separation
and purification by chromatographic column.
HPTLC was performed to separate key
component of Cardamine hirsuta and Brassica
juncea extract i.e. glucosinolates, which are
reported to have anticancerous activity. This can
be indicated from the known Rf values of the
compounds. We have found the presence of
glucosinolate at 0.24 rf values which correspond
to standard Rf values of 3-methylsulfinylpropyl
GS (0.27). Also it has been noted that Hexane:
ethyl acetate gave good results. Methanolic
organic extract was used to detect the presence
of glucosinolates in different extracts of Card
amine hirsuta and Brassica juncea. This study
further validates Cardamine hirsuta as an
anticancer therapeutic plant. This weed can be
included in diet for its therapeutic benefit.
Future work with respect to the toxicity studies
and invivo, invitro anticancer activity of
Cardamine hirsuta for cancer is envisaged. [10] Arora, Rohit, Adarsh P. Vig, and Saroj
