| "It is widely cultivated, both as an ornamental plant and as a medicinal plant... All its parts are edible. The flower has most often been consumed, making for an especially ornamental salad ingredient; it has a slightly peppery taste reminiscent of watercress, and is also used in stir fry. The flowers contain about 130 mg vitamin C per 100 grams (3.5 oz), about the same amount as is contained in parsley. Moreover, they contain up to 45 mg of lutein per 100 gr, which is the highest amount found in any edible plant." \\ | "It is widely cultivated, both as an ornamental plant and as a medicinal plant...

| | By headspace examination of the salt-saturated juice from raw vegetable tissue, 2-isopropyl-3-methoxypyrazine, 2-isobutyl-3-methoxypyrazine, and 2-sec-butyl-3-methoxypyrazine have been found important olfactory (green earthy vegetable-like) volatile components of fresh nasturtium plants. \\ |

| "Benzylglucosinolate accumulates in mature plants of Tropaeolum majus L. The biosynthetic capacity for synthesis of benzylglucosinolate and the total content of benzylglucosinolate have been investigated during plant development and in different tissues. The content increased from 5 mg of benzylglucosinolate in the fresh seed to between 200 and 400 mg in the adult plant, depending on size. The biosynthetic capacity was measured using L-[U-14C]phenylalanine as precursor. Incorporation levels of approximately 30% were obtained with green leaves, whereas the incorporation levels obtained with other tissues were in the range of 0 to 5%. Leaves were the primary site of benzylglucosinolate synthesis. The high amounts of benzylglucosinolate accumulated in other tissues (e.g. developing seeds) reflected transport of benzylglucosinolate from the leaves... The content of benzylglucosinolate in T.majus flowers increased rapidly during the process of flowering, decreased during flower withering, and increased again during seed formation.
