Indole Compounds Related to Auxins and Goitrogens of Woad (Isatis tinctoria L.).
Five conspicuous indole derivatives are present in leaves and other tissues of woad (Isatis tinctoria L.). They were identified as tryptophan, isatan B, glucobrassicin, neoglucobrassicin, and glucobrassicin-1-sulfonate. The latter three indole glucosinolates are present at levels of at least 260, 69, and 200 milligrams per kilogram fresh weight and were isolated as crystalline salts. Comparison...
متن کاملDistribution and Variation of Indole Glucosinolates in Woad (Isatis tinctoria L.).
The exceptionally high levels in woad (Isatis tinctoria L.) of three indolic goitrogens, namely glucobrassicin, neoglucobrassicin, and glucobrassicin-1-sulfonate, permit the facile study of their distribution in the plant and their changes during its development. Woad seeds contain as much as 0.23% fresh weight of glucobrassicin but no other indole glucosinolate, while 1-week-old seedlings also...
متن کاملInsecticidal and fungicidal compounds from Isatis tinctoria.
Tryptanthrin (1), indole-3-acetonitrile (2) and p-coumaric acid methylester (3) were isolated from the aerial parts of Isatis tinctoria L. The compounds show insecticidal and anti-feedant activity against termites (Reticulitermis santonensis), insect preventive and control activity against larvae of the house longhorn beetle (Hylotrupes bajulus) and fungicidal activity against the brown-rot fun...
متن کاملGlucobrassicin enhancement in woad (Isatis tinctoria) leaves by chemical and physical treatments
Woad (Isatis tinctoria), a long-known dye plant, is a noticeable source of indolic compounds, bioactive molecules exploitable as fine chemicals. Among these, glucobrassicin and its derivatives seem to play an antitumoral role, especially against mammary cancer. Since different Brassicaceae, such as broccoli and cauliflower, which are present in the human diet, contain glucobrassicin, it would b...
متن کاملEnzymatic Conversion of Indole Acetaldehyde and Naphthalene Acetaldehyde to Auxins.
A neutral substance, convertible to an acid auxin, is present in various plant extracts (5, 9) and chemical preparations (9). As indicated by a number of biological tests, the neutral substance is in all likelihood 3-indole acetaldehyde and will for convenience be designated by this name in the present paper. In a previous paper (11) it was shown that 3-indole acetaldehyde is rapidly converted ...
