Effect of salicylic acid, methyl jasmonate, ethephon and cantharidin on anthraquinone production by Rubia cordifolia callus cultures transformed with the rolB and rolC genes.
It has been suggested that the rol genes of Agrobacterium rhizogenes could play an essential role in the activation of secondary metabolite production in plant transformed cultures. This study investigated whether the content of anthraquinone phytoalexins was changed in callus cultures of Rubia cordifolia transgenic for the 35S-rolB and 35S-rolC genes in comparison with a non-transformed callus...
متن کاملRubia Tinctorum L. (Rubiaceae) or Madder as One of the Living Color to Dyeing Wool
The medicinal part of Rubia tinctorum is the dried root. The small yellowishgreen flowers are in loose, leafy, long-peduncled terminal or auxiliary cymes. The margin of the calyx is indistinct, 4- to 5-sectioned and has a tip that is curved inward. There are five stamens and an inferior ovary. The fruit is a black, pea-sized glabrous, smooth drupe containing two seeds. The perennial pl...

متن کاملEffect of Rubia tinctorum L. Extractson Carrageenan-Induced Paw Edema in Rats
Background: Inflammation is a dynamic process that is elicited in response to various harmful stimulantsthat may threaten the well-being of the host. Herbs have been traditionally used as anti-inflammatory agents since very early times. Rubia tinctorum L. is one of these herbs that havebeen used for treating inflammatory diseases in Iranian traditional medicine. Objective: This study aims at c...
متن کاملIsolation and extraction of ruberythric acid from Rubia tinctorum L. and crystal structure elucidation.
Madder (Rubia tinctorum L.) has been exploited as a dye throughout history. The roots of the plant are very rich in the highly coloured glycosidic compounds ruberythric acid and lucidin primeveroside, alongside the corresponding aglycons which can be readily formed by deglycosylation, particularly during extraction. Supported by (1)H and (13)C NMR data, the conclusive X-ray crystal structure of...
